Part I

ITEM 1. BUSINESS

General

We provide scheduled air transportation for passengers and cargo throughout the United States and around the world. Our global route network gives us a presence in every major domestic and international market. Our route network is centered around a system of hub and international gateway airports that we operate in Amsterdam, Atlanta, Cincinnati, Detroit, Memphis, Minneapolis-St. Paul, New York - LaGuardia, New York-JFK, Paris-Charles de Gaulle, Salt Lake City, Seattle and Tokyo-Narita. Each of these hub operations includes flights that gather and distribute traffic from markets in the geographic region surrounding the hub or gateway to domestic and international cities and to other hubs or gateways. Our network is supported by a fleet of aircraft that is varied in terms of size and capabilities, giving us flexibility to adjust aircraft to the network.

Other key characteristics of our route network include:


•	our alliances with foreign airlines, including our membership in SkyTeam, a global airline alliance;


•	our international joint ventures, particularly our transatlantic joint venture with Air France-KLM and Alitalia;


•	our domestic marketing alliance with Alaska Airlines, which expands our west coast service; and


•	agreements with multiple domestic regional carriers, which operate as Delta Connection.

We are incorporated under the laws of the State of Delaware. Our principal executive offices are located at Hartsfield-Jackson Atlanta International Airport in Atlanta, Georgia. Our telephone number is (404) 715-2600 and our Internet address is www.delta.com. Information contained on our website is not part of, and is not incorporated by reference in, this Form 10-K.

International Alliances

We have bilateral and multilateral marketing alliances with foreign airlines, which are an increasingly important part of our business as they improve our access to international markets and enable Delta to market expanded and globally integrated air transportation services. These arrangements include reciprocal codesharing and frequent flyer program participation and airport lounge access arrangements, and may also include joint sales and marketing coordination, co-location of airport facilities and other commercial cooperation arrangements. These alliances also often present opportunities in other areas, such as airport ground handling arrangements and aircraft maintenance insourcing.

We have international codeshare arrangements with the following international carriers: Aeroméxico, Air Europa, Air France, Alitalia, Aeroflot, China Airlines, China Eastern, China Southern, CSA Czech Airlines, KLM Royal Dutch Airlines, Korean Air, Olympic Air, VRG Linhas Aéreas (operating as GOL), Vietnam Airlines, Virgin Australia and WestJet (and affiliated carriers operating in conjunction with some of these airlines).

SkyTeam. In addition to our marketing alliance agreements with individual foreign airlines, we are a member of the SkyTeam global airline alliance. The other members of SkyTeam are Aeroflot, Aerolineas Argentinas, Aeroméxico, Air Europa, Air France, Alitalia, China Airlines, China Eastern, China Southern, CSA Czech Airlines, Kenya Airways, KLM, Korean Air, Middle East Airlines, Saudi Arabian Airlines, Tarom, Vietnam Airlines and Xiamen Airlines. Garuda Indonesia also has announced its formal intent to join SkyTeam. Through alliance arrangements with other SkyTeam carriers, Delta is able to link its network with the route networks of the other member airlines, providing opportunities for increased connecting traffic while offering enhanced customer service through reciprocal codesharing and frequent flyer arrangements and airport lounge access programs and coordinated cargo operations.

Transatlantic joint venture with Air France-KLM and Alitalia. In addition to being members in SkyTeam, we operate a transatlantic joint venture with Air France and KLM, both of which are subsidiaries of the same holding company, and Alitalia, which covers routes between North America and Europe. The joint venture agreement provides for the sharing of revenues and costs, as well as joint marketing and sales, coordinated pricing and revenue management, network planning and scheduling and other coordinated activities with respect to the parties' operations on joint venture routes.

Proposed transatlantic joint venture with Virgin Atlantic. In December 2012, in connection with entering into an agreement for the purchase by Delta from Singapore Airlines of a 49% equity stake in Virgin Atlantic Limited ("VAL"), we and Virgin Atlantic Airways entered into a joint venture agreement with respect to operations on non-stop routes between the United Kingdom and North America. The joint venture agreement provides for the sharing of revenues and costs, as well as joint marketing and sales activities, coordinated pricing and revenue management, network planning and scheduling and other coordinated activities with respect to the parties' operations on joint venture routes. We and Virgin Atlantic will file an application with the U.S. Department of Transportation for U.S. antitrust immunity with respect to the joint venture. The share purchase transaction will be reviewed by the U.S. Department of Justice and regulatory authorities in Europe and other relevant jurisdictions. The closing of the share purchase transaction is subject to certain conditions, including receipt of required governmental approvals. At the closing of the share purchase transaction, Delta will enter into a shareholders agreement with VAL and affiliates of Virgin Group (the controlling shareholder of VAL) containing provisions relating to the governance and management of VAL and the rights and obligations of the shareholders.

Transpacific joint venture with Virgin Australia Airlines. In November 2012, following the grant of U.S. antitrust immunity by the U.S. Department of Transportation and the receipt of required regulatory approvals from the Australian and New Zealand authorities, we and Virgin Australia implemented our joint venture covering operations on certain transpacific routes between North America and the South Pacific. The joint venture agreement provides for the sharing of incremental revenues on the joint venture routes, as well as joint marketing and sales activities, joint pricing and revenue management, network planning and scheduling with respect to the parties' operations on joint venture routes.

Enhanced commercial agreements with Latin American Carriers. In 2011, we entered into separate agreements with Grupo Aeroméxico, S.A.B. de C.V., the parent company of Aeroméxico, and GOL Linhas Aéreas Inteligentes, S.A, the parent company of GOL, for a strategic equity investment in each company and an exclusive commercial relationship with each company's affiliated air carrier. We invested in GOL and Aeromexico because they operate in Latin America's two largest markets, Brazil and Mexico, respectively. The agreements provide for expansion of reciprocal codesharing and frequent flyer program participation, airport lounge access arrangements, improved passenger connections and potential joint sales cooperation. In addition to our commercial cooperation arrangements for passenger service with Aeromexico, we and Aeromexico have established a joint venture relating to an engine maintenance, repair and overhaul operation that will be located in Queretaro, Mexico.

Domestic Alliances

We have entered into a marketing alliance with Alaska Airlines, which includes reciprocal codesharing and frequent flyer and airport lounge access arrangements. Our alliance agreement with Alaska Airlines provides for extensive cooperation with respect to our west coast presence. We also have reciprocal codesharing and frequent flyer and airport lounge access arrangements with Hawaiian Airlines.

Regional Carriers

We have air service agreements with multiple domestic regional air carriers that feed traffic to our route system by serving passengers primarily in small-and medium-sized cities. These arrangements enable us to increase the number of flights we have available in certain locations and to better match capacity with demand. Approximately 21% of our passenger revenue in 2012 was related to flying by regional air carriers.

Through our regional carrier program, we have contractual arrangements with seven regional carriers to operate regional jet and, in certain cases, turbo-prop aircraft using our “DL” designator code. We have contractual arrangements with: ExpressJet Airlines, Inc. and SkyWest Airlines, Inc., both subsidiaries of SkyWest, Inc.; Chautauqua Airlines, Inc. and Shuttle America Corporation, both subsidiaries of Republic Airways Holdings, Inc.; Pinnacle Airlines, Inc., a subsidiary of Pinnacle Airlines Corp.; Compass Airlines, Inc. (“Compass”) and GoJet Airlines, LLC, both subsidiaries of Trans States Holdings, Inc. (“Trans States”). In connection with the exit of Pinnacle Airlines Corp. and Pinnacle Airlines, Inc. from bankruptcy reorganization, we expect to become the sole equity holder of Pinnacle Airlines Corp. as the result of being the primary provider of financing during its bankruptcy.

Our contractual agreements with regional carriers primarily are capacity purchase arrangements, under which we control the scheduling, pricing, reservations, ticketing and seat inventories for the regional carriers' flights operating under our “DL” designator code, and we are entitled to all ticket, cargo, mail and in-flight and ancillary revenues associated with these flights. We pay those airlines an amount, as defined in the applicable agreement, which is based on a determination of their cost of operating those flights and other factors intended to approximate market rates for those services. These capacity purchase agreements are long-term agreements, usually with initial terms of at least 10 years, which grant us the option to extend the initial term. Certain of these agreements provide us the right to terminate the entire agreement, or in some cases remove some of the aircraft from the scope of the agreement, for convenience at certain future dates.

A portion of the flights operated for us by SkyWest Airlines are structured as revenue proration agreements. These proration agreements establish a fixed dollar or percentage division of revenues for tickets sold to passengers traveling on connecting flight itineraries.

Fuel

Our results of operations are significantly impacted by changes in the price and availability of aircraft fuel. The following table shows our aircraft fuel consumption and costs.



Year	Gallons Consumed⁽¹⁾ (Millions)	Cost⁽¹⁾⁽²⁾ (Millions)		Average Price Per Gallon⁽¹⁾⁽²⁾		Percentage of Total Operating Expense⁽¹⁾⁽²⁾
2012	3,769	$	12,251	$	3.25	36	%
2011	3,856	$	11,783	$	3.06	36	%
2010	3,823	$	8,901	$	2.33	30	%


⁽¹⁾	Includes the operations of our contract carriers under capacity purchase agreements.


⁽²⁾	Includes fuel hedge (losses) gains under our fuel hedging program of $(66) million, $420 million and $(89) million for 2012, 2011 and 2010, respectively.

General

Jet fuel costs have continued to increase in recent years, making fuel expense our single largest expense. We have historically purchased most of our aircraft fuel under contracts that establish the price based on various market indices and therefore do not provide material protection against price increases or assure the availability of our fuel supplies. We also purchase aircraft fuel on the spot market, from off-shore sources and under contracts that permit the refiners to set the price.

Monroe Energy

Because global demand for jet fuel and related products is increasing at the same time that jet fuel refining capacity is decreasing in the U.S. (particularly in the Northeast), the refining margin reflected in the prices we pay for jet fuel has increased. Our wholly-owned subsidiaries, Monroe Energy, LLC and MIPC, LLC (collectively, “Monroe”), acquired the Trainer refinery and related assets located near Philadelphia, Pennsylvania in June 2012 as part of our strategy to mitigate the increasing cost of the refining margin we are paying.

Refinery Acquisition. Monroe invested $180 million to acquire the refinery from Phillips 66. Monroe received a $30 million grant from the Commonwealth of Pennsylvania. The acquisition includes pipelines and terminal assets that allow the refinery to supply jet fuel to our airline operations throughout the Northeastern U.S., including our New York hubs at LaGuardia and John F. Kennedy International Airport ("JFK"). Prior to the transaction, Phillips 66 had shut down operations at the refinery.

Refinery Operations. The facility is capable of refining 185,000 barrels of crude oil per day. In addition to jet fuel, the refinery's production consists of gasoline, diesel and refined products (“non-jet fuel products”). Production at the refinery restarted in September 2012. BP is the primary supplier of crude oil used by the refinery under a three year agreement. We are also exploring other sources of crude oil supply, such as bringing supply to the refinery by rail from the Bakken oil field in North Dakota.

Strategic Agreements. Under a multi-year agreement, we are exchanging a significant portion of the non-jet fuel products with Phillips 66 for jet fuel to be used in our airline operations. Substantially all of the remaining production of non-jet fuel products is being sold to BP under a long-term buy/sell agreement effectively exchanging those non-jet fuel products for jet fuel. Our agreement with Phillips 66 requires us to deliver specified quantities of non-jet fuel products and they are required to deliver jet fuel to us. If we or Phillips 66 do not have the specified quantity and type of product available, the delivering party is required to procure any such shortage to fulfill its obligation under the agreement. Substantially all of the refinery's expected production of non-jet fuel products is included in these agreements.

Segments. Because the products and services of Monroe's refinery operations are discrete from our airline services, segment results are prepared for our airline segment and our refinery segment. Financial information on our segment reporting can be found in Note 2 of the Notes to the Consolidated Financial Statements.

Fuel Hedging Program

We actively manage our fuel price risk through a hedging program intended to reduce the financial impact on us from changes in the price of jet fuel. This fuel hedging program utilizes several different contract and commodity types. The economic effectiveness of this hedge portfolio is frequently tested against our financial targets. The hedge portfolio is rebalanced from time to time according to market conditions, which may result in locking in gains or losses on hedge contracts prior to their settlement dates.

Fuel Supply Availability

We are currently able to obtain adequate supplies of aircraft fuel, including through our purchases from Monroe, but it is impossible to predict the future availability or price of aircraft fuel. Weather-related events, natural disasters, political disruptions or wars involving oil-producing countries, changes in government policy concerning aircraft fuel production, transportation or marketing, changes in aircraft fuel production capacity, environmental concerns and other unpredictable events may result in fuel supply shortages and fuel price increases in the future.

Frequent Flyer Program

Our SkyMiles^® frequent flyer program is designed to retain and increase traveler loyalty by offering incentives to customers to increase travel on Delta. The SkyMiles program allows program members to earn mileage for travel awards by flying on Delta, Delta's regional carriers and other participating airlines. Mileage credit may also be earned by using certain services offered by program participants, such as credit card companies, hotels and car rental agencies. In addition, individuals and companies may purchase mileage credits. Miles do not expire, but are subject to all program rules. We reserve the right to terminate the program with six months advance notice, and to change the program's terms and conditions at any time without notice.

SkyMiles program mileage credits can be redeemed for air travel on Delta and participating airlines, for membership in our Delta Sky Clubs^®and for other program participant awards. Mileage credits are subject to certain transfer restrictions and travel awards are subject to capacity-controlled seating. In 2012, program members redeemed more than 262 billion miles in the SkyMiles program for 11 million award redemptions. During this period, 8% of revenue miles flown on Delta were from award travel.

Other Businesses

Cargo

Through our global network, our cargo operations are able to connect all of the world's major freight gateways. We generate cargo revenues in domestic and international markets primarily through the use of cargo space on regularly scheduled passenger aircraft. We are a member of SkyTeam Cargo, a global airline cargo alliance, whose other members are Aeroflot, Aeromexico Cargo, Air France-KLM Cargo, Alitalia Cargo, China Airlines Cargo, China Southern Cargo, Czech Airlines Cargo and Korean Air Cargo. SkyTeam Cargo offers a global network spanning six continents.

Delta TechOps, Delta Global Services, MLT Vacations and Delta Private Jets

We have several other businesses arising from our airline operations, including aircraft maintenance, repair and overhaul (“MRO”), staffing services for third parties, vacation wholesale operations and our private jet operations. In 2012, the total revenue from these businesses was approximately $1 billion.


•	In addition to providing maintenance and engineering support for our fleet of over 700 aircraft, our MRO operation, known as Delta TechOps, serves aviation and airline customers from around the world.


•	Our staffing services business, Delta Global Services, provides staffing services, professional security, training services and aviation solutions.


•	Our vacation wholesale business, MLT Vacations, provides vacation packages.


•	Our private jet operations, Delta Private Jets, provides aircraft charters, aircraft management and programs allowing members to purchase flight time by the hour.

Distribution and Expanded Product Offerings

Our tickets are sold through various distribution channels including telephone reservations, delta.com, global distribution systems and online travel agencies. An increasing number of our tickets are sold through delta.com, which reduces our distribution costs and gives us closer contact with our customers. We launched a new delta.com platform in November 2012, which we expect will result in additional purchases of tickets and services through that channel.

We are transforming distribution from a commodity approach to a differentiated and merchandised approach. We expect that the merchandising initiatives we are implementing, primarily through delta.com, will generate additional revenue opportunities for us and will improve the experience of our customers. We provide our customers with opportunities to purchase what they value, such as first class upgrades, economy comfort seating, WiFi access and SkyClub passes. We expect to benefit from increased traffic on delta.com through a combination of advertising revenue and sales of third party merchandise and services such as car rentals, hotels and trip insurance.

Competition

The airline industry is highly competitive, marked by significant competition with respect to routes, fares, schedules (both timing and frequency), services, products, customer service and frequent flyer programs. The industry is going through a period of transformation through consolidation, both domestically and internationally, and changes in international alliances. Consolidation in the airline industry and changes in international alliances have altered and will continue to alter the competitive landscape in the industry by resulting in the formation of airlines and alliances with increased financial resources, more extensive global networks and altered cost structures. In addition, other network carriers have also significantly reduced their costs over the last several years including through restructuring and bankruptcy reorganization. American Airlines is nearing the end of its bankruptcy restructuring, which is enabling it to reduce its costs. Our ability to compete effectively depends, in part, on our ability to maintain a competitive cost structure.

Domestic

Our domestic operations are subject to competition from both traditional network and discount carriers, some of which may have lower costs than we do and provide service at low fares to destinations served by us. In particular, we face significant competition at our domestic hub airports in Atlanta, Cincinnati, Detroit, Memphis, Minneapolis-St. Paul, New York-LaGuardia, New York-JFK and Salt Lake City either directly at those airports or at the hubs of other airlines that are located in close proximity to our hubs. We also face competition in smaller to medium-sized markets from regional jet operators.

International

Our international operations are subject to competition from both domestic and foreign carriers. Through alliance and other marketing and codesharing agreements with foreign carriers, U.S. carriers have increased their ability to sell international transportation, such as services to and beyond traditional European and Asian gateway cities. Similarly, foreign carriers have obtained increased access to interior U.S. passenger traffic beyond traditional U.S. gateway cities through these relationships. In particular, alliances formed by domestic and foreign carriers, including SkyTeam, the Star Alliance (among United Airlines, Lufthansa German Airlines, Air Canada, All Nippon Airways and others) and the oneworld alliance (among American Airlines, British Airways, Iberia, Qantas and others) have significantly increased competition in international markets.

Increased competition has also emerged from well-funded carriers in the Gulf region, including Emirates, Etihad and Qatar. These carriers have large numbers of international widebody aircraft on order and are increasing service to the United States from their hubs in the Middle East. Several of these carriers, along with carriers from China, India and Latin America, are government supported or funded, which has allowed them to grow quickly, reinvest in their product and expand their global presence at the expense of U.S. airlines. In addition, the adoption of liberalized Open Skies Aviation Agreements with an increasing number of countries around the world, including in particular the Open Skies Treaties that the U.S. has with the Member States of the European Union, Japan and the Gulf states, could significantly increase competition among carriers serving those markets.

Several joint ventures among U.S. and foreign carriers, including our transatlantic joint venture with Air France-KLM and Alitalia and our transpacific joint venture with Virgin Australia, have received grants of antitrust immunity allowing the participating carriers to coordinate schedules, pricing, sales and inventory. Other joint ventures that have received anti-trust immunity include a transatlantic alliance among United, Air Canada and Lufthansa, a transpacific joint venture among United and All Nippon Airways, a transatlantic joint venture among American, British Airways and Iberia and a transpacific joint venture between American and Japan Air Lines.

Regulatory Matters

The Department of Transportation (“DOT”) and the Federal Aviation Administration (the “FAA”) exercise regulatory authority over air transportation in the U.S. The DOT has authority to issue certificates of public convenience and necessity required for airlines to provide domestic air transportation. An air carrier that the DOT finds fit to operate is given authority to operate domestic and international air transportation (including the carriage of passengers and cargo). Except for constraints imposed by regulations regarding “Essential Air Services,” which are applicable to certain small communities, airlines may terminate service to a city without restriction.

The DOT has jurisdiction over certain economic and consumer protection matters, such as unfair or deceptive practices and methods of competition, advertising, denied boarding compensation, baggage liability and disabled passenger transportation. The DOT also has authority to review certain joint venture agreements between major carriers and engages in regulation of economic matters such as slot transactions. The FAA has primary responsibility for matters relating to the safety of air carrier flight operations, including airline operating certificates, control of navigable air space, flight personnel, aircraft certification and maintenance and other matters affecting air safety.

Authority to operate international routes and international codesharing arrangements is regulated by the DOT and by the governments of the foreign countries involved. International certificate authorities are also subject to the approval of the U.S. President for conformance with national defense and foreign policy objectives.

The Transportation Security Administration and the U.S. Customs and Border Protection, each a division of the Department of Homeland Security, are responsible for certain civil aviation security matters, including passenger and baggage screening at U.S. airports and international passenger prescreening prior to entry into or departure from the U.S.

Airlines are also subject to various other federal, state, local and foreign laws and regulations. For example, the U.S. Department of Justice has jurisdiction over airline competition matters. The U.S. Postal Service has authority over certain aspects of the transportation of mail. Labor relations in the airline industry, as discussed below, are generally governed by the Railway Labor Act. Environmental matters are regulated by various federal, state, local and foreign governmental entities. Privacy of passenger and employee data is regulated by domestic and foreign laws and regulations.

Fares and Rates

Airlines set ticket prices in all domestic and most international city pairs with minimal governmental regulation, and the industry is characterized by significant price competition. Certain international fares and rates are subject to the jurisdiction of the DOT and the governments of the foreign countries involved. Many of our tickets are sold by travel agents, and fares are subject to commissions, overrides and discounts paid to travel agents, brokers and wholesalers.

Route Authority

Our flight operations are authorized by certificates of public convenience and necessity and also by exemptions and limited-entry frequency awards issued by the DOT. The requisite approvals of other governments for international operations are controlled by bilateral agreements (and a multilateral agreement in the case of the U.S. and the European Union) with, or permits or approvals issued by, foreign countries. Because international air transportation is governed by bilateral or other agreements between the U.S. and the foreign country or countries involved, changes in U.S. or foreign government aviation policies could result in the alteration or termination of such agreements, diminish the value of our international route authorities or otherwise affect our international operations. Bilateral agreements between the U.S. and various foreign countries served by us are subject to renegotiation from time to time. The U.S. government has negotiated “open skies” agreements with many countries, which allow unrestricted access between the U.S. and the foreign markets. These agreements include separate agreements with the European Union and Japan.

Certain of our international route authorities are subject to periodic renewal requirements. We request extension of these authorities when and as appropriate. While the DOT usually renews temporary authorities on routes where the authorized carrier is providing a reasonable level of service, there is no assurance this practice will continue in general or with respect to a specific renewal. Dormant route authorities may not be renewed in some cases, especially where another U.S. carrier indicates a willingness to provide service.

Airport Access

Operations at four major domestic airports and certain foreign airports served by us are regulated by governmental entities through allocations of “slots” or similar regulatory mechanisms which limit the rights of carriers to conduct operations at those airports. Each slot represents the authorization to land at or take off from the particular airport during a specified time period.

In the U.S., the FAA currently regulates the allocation of slots, slot exemptions, operating authorizations, or similar capacity allocation mechanisms at Reagan National in Washington, D.C. and LaGuardia, John F. Kennedy International Airport (“JFK”) and Newark in the New York City area. Our operations at these airports generally require the allocation of slots or analogous regulatory authorizations. Similarly, our operations at Tokyo's Narita and Haneda Airports, London's Gatwick and Heathrow airports and other international airports are regulated by local slot coordinators pursuant to the International Air Transport Association's Worldwide Scheduling Guidelines and applicable local law. We currently have sufficient slots or analogous authorizations to operate our existing flights, and we have generally been able to obtain the rights to expand our operations and to change our schedules. There is no assurance, however, that we will be able to do so in the future because, among other reasons, such allocations are subject to changes in governmental policies.

Environmental Matters

Emissions. The U.S. Environmental Protection Agency (the “EPA”) is authorized to regulate aircraft emissions and has historically implemented emissions control standards previously adopted by the International Civil Aviation Organization (“ICAO”). Our aircraft comply with existing EPA standards as applicable by engine design date. The ICAO has adopted two additional aircraft engine emissions standards, the first of which is applicable to engines certified after December 31, 2007, and the second of which is applicable to engines certified after December 31, 2013. In June 2012, the EPA published a final rulemaking for new emission standards for oxides of nitrogen (NOx), adopting ICAO's additional standards. Included in the rule are two new tiers of more stringent emission standards for NOx. These standards, referred to as the Tier 6 standards, become effective for newly-manufactured aircraft engines beginning in 2013.

Concern about aviation environmental issues, including climate change and greenhouse gases, has led to taxes on our operations in the United Kingdom and in Germany, both of which have levied taxes directly on our customers. We may face additional regulation of aircraft emissions in the United States and abroad and become subject to further taxes, charges or additional requirements to obtain permits or purchase allowances or emission credits for greenhouse gas emissions in various jurisdictions. This could result in taxation or permitting requirements from multiple jurisdictions for the same operations. Ongoing bilateral discussions between the United States and other nations as well as discussions at the ICAO Assembly and Conference of the Parties, most recently in Doha, Qatar in December 2012, may lead to international treaties or other actions focusing on reducing greenhouse gas emissions from aviation.

The European Union has required its member states to implement regulations including aviation in its Emissions Trading Scheme (“ETS”). Under these regulations, any airline with flights originating or landing in the European Union is subject to the ETS and, beginning in 2012, is required to purchase emissions allowances if the airline exceeds the number of free allowances allocated to it under the ETS. In November 2012, the European Commission proposed to defer airlines' compliance obligations for non-European flights and suspended related non-compliance sanctions until after the 38th ICAO Assembly to be held in late September and early October of 2013. The European Commission has taken this action to give the process at ICAO time to come to a conclusion. Under the proposal, airlines will not face enforcement action if they do not surrender allowances for their emissions related to flights operated to and from non-EU destinations; however, all intra-EU flights on any carrier (based in the EU or not) will still have to comply with the requirements of the ETS. Legislation is required to implement this proposed change and a co-decision by both the EU Member States and the European Parliament on this change is necessary. A decision is expected before April 2013. Further, at the end of November 2012, the United State government enacted legislation exempting U.S. airlines from the ETS.

Cap and trade restrictions have also been proposed in the United States. In addition, other legislative or regulatory action, including by the EPA, to regulate greenhouse gas emissions is possible. In particular, the EPA has found that greenhouse gases threaten the public health and welfare, which could result in regulation of greenhouse gas emissions from aircraft. In the event that legislation or regulation is enacted in the U.S. or in the event similar legislation or regulation is enacted in jurisdictions other than the European Union where we operate or where we may operate in the future, it could result in significant costs for us and the airline industry. In addition to direct costs, such regulation may have a greater effect on the airline industry through increases in fuel costs that could result from fuel suppliers passing on increased costs that they incur under such a system. We are monitoring and evaluating the potential impact of such legislative and regulatory developments.

We seek to minimize the impact of greenhouse gas emissions from our operations through reductions in our fuel consumption and other efforts and have realized reductions in our greenhouse gas emission levels since 2005. We have reduced the fuel needs of our aircraft fleet through the retirement and replacement of certain elements of our fleet and with newer, more fuel efficient aircraft. In addition, we have implemented fuel saving procedures in our flight and ground support operations that further reduce carbon emissions. We are also supporting efforts to develop alternative fuels and efforts to modernize the air traffic control system in the U.S., as part of our efforts to reduce our emissions and minimize our impact on the environment.

Noise. The Airport Noise and Capacity Act of 1990 recognizes the rights of operators of airports with noise problems to implement local noise abatement programs so long as such programs do not interfere unreasonably with interstate or foreign commerce or the national air transportation system. This statute generally provides that local noise restrictions on Stage 3 aircraft first effective after October 1, 1990, require FAA approval. While we have had sufficient scheduling flexibility to accommodate local noise restrictions in the past, our operations could be adversely impacted if locally-imposed regulations become more restrictive or widespread.

Refinery Matters. Monroe's operation of the Trainer Refinery is subject to numerous environmental laws and extensive regulations, including those relating to the discharge of materials into the environment, waste management, pollution prevention measures and greenhouse gas emissions. If Monroe violates or fails to comply with these laws and regulations, Monroe could be fined or otherwise sanctioned, which, if significant, could have a material adverse effect on our financial results. In addition, the enactment of new environmental laws and regulations, including any laws or regulations relating to greenhouse gas emissions, could significantly increase the level of expenditures required for environmental matters for Monroe.

Other Environmental Matters. We had been identified by the EPA as a potentially responsible party (a “PRP”) with respect to certain Superfund Sites, and entered into consent decrees or settlements regarding some of these sites. Our alleged disposal volume at each of these sites was small or was considered de minimis when compared to the total contributions of all PRPs at each site.

We are aware of soil and/or ground water contamination present on our current or former leaseholds at several domestic airports. To address this contamination, we have a program in place to investigate and, if appropriate, remediate these sites. Although the ultimate outcome of these matters cannot be predicted with certainty, we believe that the resolution of these matters will not have a material adverse effect on our consolidated financial statements.

We are also subject to various other federal, state and local laws governing environmental matters, including the management and disposal of chemicals, waste and hazardous materials, protection of surface and subsurface waters and regulation of air emissions and aircraft drinking water.

Civil Reserve Air Fleet Program

We participate in the Civil Reserve Air Fleet program (the “CRAF Program”), which permits the U.S. military to use the aircraft and crew resources of participating U.S. airlines during airlift emergencies, national emergencies or times of war. We have agreed to make available under the CRAF Program a portion of our international long-range aircraft during the contract period ending September 30, 2013. We have also committed aircraft to international short-range requirements. The CRAF Program has only been activated twice since it was created in 1951.

Employee Matters

Railway Labor Act

Our relations with labor unions representing our airline employees in the U.S. are governed by the Railway Labor Act. Under the Railway Labor Act, a labor union seeking to represent an unrepresented craft or class of employees is required to file with the National Mediation Board (the “NMB”) an application alleging a representation dispute, along with authorization cards signed by at least 50% of the employees in that craft or class. The NMB then investigates the dispute and, if it finds the labor union has obtained a sufficient number of authorization cards, conducts an election to determine whether to certify the labor union as the collective bargaining representative of that craft or class. A labor union will be certified as the representative of the employees in a craft or class if more than 50% of votes cast are for that union. A certified labor union would commence negotiations toward a collective bargaining agreement with the employer.

Under the Railway Labor Act, a collective bargaining agreement between an airline and a labor union does not expire, but instead becomes amendable as of a stated date. Either party may request that the NMB appoint a federal mediator to participate in the negotiations for a new or amended agreement. If no agreement is reached in mediation, the NMB may determine, at any time, that an impasse exists and offer binding arbitration. If either party rejects binding arbitration, a 30-day “cooling off” period begins. At the end of this 30-day period, the parties may engage in “self help,” unless the U.S. President appoints a Presidential Emergency Board (“PEB”) to investigate and report on the dispute. The appointment of a PEB maintains the “status quo” for an additional 60 days. If the parties do not reach agreement during this period, the parties may then engage in “self help.” “Self help” includes, among other things, a strike by the union or the imposition of proposed changes to the collective bargaining agreement by the airline. Congress and the President have the authority to prevent “self help” by enacting legislation that, among other things, imposes a settlement on the parties.

Collective Bargaining

As of December 31, 2012, we had approximately 74,000 full-time equivalent employees, approximately 15% of whom were represented by unions. The following table shows our domestic airline employee groups that are represented by unions.



Employee Group	Approximate Number of Active Employees Represented	Union	Date on which Collective Bargaining Agreement Becomes Amendable
Delta Pilots	10,700	ALPA	December 31, 2015
Delta Flight Superintendents (Dispatchers)	340	PAFCA	December 31, 2013

In addition, 220 refinery employees of Monroe are represented by the United Steel Workers under an agreement that expires on February 26, 2015. This agreement is governed by the National Labor Relations Act, which generally allows either party to engage in self-help upon the expiration of the agreement.

Labor unions periodically engage in organizing efforts to represent various groups of our employees, including at our operating subsidiaries, that are not represented for collective bargaining purposes.

ITEM 1A. RISK FACTORS

Risk Factors Relating to Delta

Our business and results of operations are dependent on the price of aircraft fuel. High fuel costs or cost increases, including in the cost of crude oil, could have a materially adverse effect on our operating results.

Our operating results are significantly impacted by changes in the price of aircraft fuel. Fuel prices have increased substantially since the middle part of the last decade and have been extremely volatile during the last several years. In 2012, our average fuel price per gallon was $3.25, a 6% increase from our average fuel price in 2011. In 2011, our average fuel price per gallon was $3.06, a 31% increase from our average fuel price in 2010. In 2010, our average fuel price per gallon was $2.33, an 8% increase from an average fuel price of $2.15 in 2009, which in turn was significantly higher than fuel prices just a few years earlier. Fuel costs represented 36%, 36% and 30% of our operating expense in 2012, 2011 and 2010, respectively. Volatility in fuel costs has had a significant negative effect on our results of operations and financial condition.

Our ability to pass along the increased costs of fuel to our customers may be affected by the competitive nature of the airline industry. We often have not been able to increase our fares to offset fully the effect of increased fuel costs in the past and we may not be able to do so in the future. This is particularly the case when fuel prices increase rapidly. Because passengers often purchase tickets well in advance of their travel, a significant increase in fuel price may result in the fare charged not covering that increase.

We expect to acquire a significant amount of jet fuel from our wholly-owned subsidiary, Monroe, and through strategic agreements that Monroe has with BP and Phillips 66. The cost of the fuel we purchase under these arrangements will remain subject to volatility in the cost of crude oil and jet fuel. In addition, we will continue to purchase a significant amount of aircraft fuel in addition to what we obtain from Monroe. Our aircraft fuel purchase contracts do not provide material protection against price increases as these contracts typically establish the price based on various market indices. We also purchase aircraft fuel on the spot market, from offshore sources and under contracts that permit the refiners to set the price.

Our business and results of operations are also dependent on the availability of aircraft fuel. Significant disruptions in the supply of aircraft fuel, including from our wholly-owned subsidiary, would materially adversely affect our operations and operating results.

We are currently able to obtain adequate supplies of aircraft fuel, but it is impossible to predict the future availability of aircraft fuel. Weather-related events, natural disasters, political disruptions or wars involving oil-producing countries, changes in governmental policy concerning aircraft fuel production, transportation, taxes or marketing, environmental concerns and other unpredictable events may result in crude oil and fuel supply shortages in the future. Shortages in fuel supplies could have negative effects on our results of operations and financial condition.

Because we plan to acquire a large amount of our jet fuel from Monroe, the disruption or interruption of production at the refinery could have an impact on our ability to acquire jet fuel needed for our operations. Disruptions or interruptions of production at the refinery could result from various sources including a major accident or mechanical failure, interruption of supply or delivery of crude oil, work stoppages relating to organized labor issues, or damage from severe weather or other natural or man-made disasters, including acts of terrorism. If the refinery were to experience an interruption in operations, disruptions in fuel supplies could have negative effects on our results of operations and financial condition. In addition, the financial benefits we expect to achieve from buying fuel from Monroe could be materially adversely affected (to the extent not recoverable through insurance) because of lost production and repair costs.

Under a strategic agreement that Monroe has with Phillips 66, Monroe is exchanging non-jet fuel products for jet fuel for use in our airline operations. Monroe is required to deliver specified quantities of non-jet fuel products to Phillips 66 and Phillips 66 is required to deliver specified quantities of jet fuel to us. If either party does not have the specified quantity or type of product available, that party is required to procure any such shortage to fulfill its obligation under the exchange agreements. If the refinery experiences a significant interruption in operations, Monroe may be required to expend substantial amounts to purchase the products it is required to deliver, which could have a material adverse effect on our consolidated financial results of operations.

In addition, the strategic agreements utilize market prices for the products being exchanged. If Monroe's cost of producing the non-jet fuel products that it is required to deliver under these agreements exceeds the value it receives for those products, the financial benefits we expect to achieve through the ownership of the refinery and our consolidated results of operations could be materially adversely affected.

Our fuel hedging activities are intended to reduce the financial impact from changes in the price of jet fuel. Our obligation to post collateral in connection with our hedge contracts may have a substantial impact on our short-term liquidity.

Our fuel hedge contracts contain margin funding requirements. The margin funding requirements may cause us to post margin to counterparties or may cause counterparties to post margin to us as market prices in the underlying hedged items change. If fuel prices decrease significantly from the levels existing at the time we enter into fuel hedge contracts, we may be required to post a significant amount of margin, which could have a material adverse impact on the level of our unrestricted cash and cash equivalents and short-term investments.

Our funding obligation with respect to defined benefit pension plans we sponsor is significant and can vary materially because of changes in investment asset returns and values.

As of December 31, 2012, our defined benefit pension plans had an estimated benefit obligation of approximately $21.5 billion and were funded through assets with a value of approximately $8.2 billion. The benefit obligation is significantly affected by investment asset returns and changes in interest rates, neither of which is in our control. We estimate that our funding requirement for our defined benefit pension plans, which are governed by ERISA and have been frozen for future accruals, is approximately $675 million in 2013. Estimates of pension plan funding requirements can vary materially from actual funding requirements because the estimates are based on various assumptions concerning factors outside our control, including, among other things, the market performance of assets; statutory requirements; and demographic data for participants, including the number of participants and the rate of participant attrition. Results that vary significantly from our assumptions could have a material impact on our future funding obligations.

Our substantial indebtedness may limit our financial and operating activities and may adversely affect our ability to incur additional debt to fund future needs.

We have substantial indebtedness, which could:


•	make us more vulnerable to economic downturns, adverse industry conditions or catastrophic external events;


•	limit our ability to borrow additional money for working capital, restructurings, capital expenditures, research and development, investments, acquisitions or other purposes, if needed, and increasing the cost of any of these borrowings;


•	limit our ability to withstand competitive pressures; and/or


•	limit our flexibility in responding to changing business and economic conditions, including increased competition and demand for new services, placing us at a disadvantage when compared to our competitors that have less debt, and making us more vulnerable than our competitors who have less debt to a downturn in our business, industry or the economy in general.

In addition, a substantial level of indebtedness, particularly because a significant portion of our assets are currently subject to liens, could limit our ability to obtain additional financing on acceptable terms or at all for working capital, capital expenditures and general corporate purposes. We have historically had substantial liquidity needs in the operation of our business. These liquidity needs could vary significantly and may be affected by general economic conditions, industry trends, performance and many other factors not within our control.

Agreements governing our debt, including credit agreements and indentures, include financial and other covenants that impose restrictions on our financial and business operations.

Our credit facilities and indentures for secured notes have various financial and other covenants that require us to maintain, depending on the particular agreement, minimum fixed charge coverage ratios, minimum liquidity and/or minimum collateral coverage ratios. The value of the collateral that has been pledged in each facility may change over time, which may be reflected in appraisals of collateral required by our credit agreements and indentures. These changes could result from factors that are not under our control. A decline in the value of collateral could result in a situation where we may not be able to maintain the collateral coverage ratio. In addition, the credit facilities and indentures contain other negative covenants customary for such financings. If we fail to comply with these covenants and are unable to obtain a waiver or amendment, an event of default would result. These covenants are subject to important exceptions and qualifications.

The credit facilities and indentures also contain other events of default customary for such financings. If an event of default were to occur, the lenders or the trustee could, among other things, declare outstanding amounts due and payable, and our cash may become restricted. We cannot provide assurance that we would have sufficient liquidity to repay or refinance the borrowings or notes under any of the credit facilities if such amounts were accelerated upon an event of default. In addition, an event of default or declaration of acceleration under any of the credit facilities or the indentures could also result in an event of default under other of our financing agreements.

Employee strikes and other labor-related disruptions may adversely affect our operations.

Our business is labor intensive, utilizing large numbers of pilots, flight attendants, aircraft maintenance technicians, ground support personnel and other personnel. As of December 31, 2012, approximately 15% of our workforce was unionized. Relations between air carriers and labor unions in the United States are governed by the Railway Labor Act, which provides that a collective bargaining agreement between an airline and a labor union does not expire, but instead becomes amendable as of a stated date. The Railway Labor Act generally prohibits strikes or other types of self-help actions both before and after a collective bargaining agreement becomes amendable, unless and until the collective bargaining processes required by the Railway Labor Act have been exhausted. Monroe's relations with unions representing its employees are governed by the National Labor Relations Act ("NLRA"), which generally allows self-help after a collective bargaining agreement expires.

If we or our affiliates are unable to reach agreement with any of our unionized work groups on future negotiations regarding the terms of their collective bargaining agreements or if additional segments of our workforce become unionized, we may be subject to work interruptions or stoppages, subject to the requirements of the Railway Labor Act or the NLRA, as the case may be. Strikes or labor disputes with our unionized employees may adversely affect our ability to conduct business. Likewise, if third party regional carriers with whom we have contract carrier agreements are unable to reach agreement with their unionized work groups in current or future negotiations regarding the terms of their collective bargaining agreements, those carriers may be subject to work interruptions or stoppages, subject to the requirements of the Railway Labor Act, which could have a negative impact on our operations.

Extended interruptions or disruptions in service at one of our hub airports could have a material adverse impact on our operations.

Our business is heavily dependent on our operations at the Atlanta airport and at our other hub airports in Amsterdam, Cincinnati, Detroit, Memphis, Minneapolis-St. Paul, New York-LaGuardia, New York-JFK, Paris-Charles de Gaulle, Salt Lake City and Tokyo-Narita. Each of these hub operations includes flights that gather and distribute traffic from markets in the geographic region surrounding the hub to other major cities and to other Delta hubs. A significant interruption or disruption in service at one of our hubs could have a serious impact on our business, financial condition and results of operations.

We are dependent on technology in our operations, and if our technology fails or we are unable to continue to invest in new technology, our business may be adversely affected.

We have become increasingly dependent on technology initiatives to reduce costs and to enhance customer service in order to compete in the current business environment. For example, we have made and continue to make significant investments in delta.com, check-in kiosks, mobile device applications and related initiatives. The performance and reliability of the technology are critical to our ability to attract and retain customers and our ability to compete effectively. Because of the rapid pace of new developments, these initiatives will continue to require significant capital investments in our technology infrastructure. If we are unable to make these investments, our business and operations could be negatively affected.

Disruptions or security breaches of our information technology infrastructure could interfere with our operations, compromise customer information and expose us to liability, possibly causing our business and reputation to suffer.

Any internal technology error or failure impacting systems hosted internally at our data centers or externally at third party locations, or large scale external interruption in technology infrastructure we depend on, such as power, telecommunications or the internet, may disrupt our technology network. Any individual, sustained or repeated failure of technology could impact our customer service and result in increased costs. Our technology systems and related data may also be vulnerable to a variety of sources of interruption due to events beyond our control, including natural disasters, terrorist attacks, telecommunications failures, computer viruses, hackers and other security issues. While we have in place, and continue to invest in, technology security initiatives and disaster recovery plans, these measures may not be adequate or implemented properly to prevent a business disruption and its adverse financial and reputational consequences to our business.

In addition, as a part of our ordinary business operations, we collect and store sensitive data, including personal information of our customers and employees. The secure operation of the networks and systems on which this type of information is stored, processed and maintained is critical to our business operations and strategy. Any compromise of our technology systems resulting from attacks by hackers or breaches due to employee error or malfeasance could result in the loss, disclosure, misappropriation of or access to customers', employees' or business partners' information. Any such loss, disclosure, misappropriation or access could result in legal claims or proceedings, liability or regulatory penalties under laws protecting the privacy of personal information, disrupt operations and damage our reputation, any or all of which could adversely affect our business.

Our primary credit card processors have the ability to take significant holdbacks in certain circumstances. The initiation of such holdbacks likely would have a material adverse effect on our liquidity.

Most of the tickets we sell are paid for by customers who use credit cards. Our primary credit card processing agreements provide that no holdback of receivables or reserve is required except in certain circumstances, including if we do not maintain a required level of unrestricted cash. If circumstances were to occur that would allow American Express or our VISA/MasterCard processor to initiate a holdback, the negative impact on our liquidity likely would be material.

We are at risk of losses and adverse publicity stemming from any accident involving our aircraft.

An aircraft crash or other accident could expose us to significant tort liability. In the event that the insurance that we carry to cover damages arising from future accidents is not adequate, we may be forced to bear substantial losses from an accident. In addition, any accident involving an aircraft that we operate or an aircraft that is operated by an airline that is one of our regional carriers or codeshare partners could create a public perception that our aircraft are not safe or reliable, which could harm our reputation, result in air travelers being reluctant to fly on our aircraft and harm our business.

Our business is subject to the effects of weather and natural disasters and seasonality, which can cause our results to fluctuate.

Our results of operations will reflect fluctuations from weather, natural disasters and seasonality. Severe weather conditions and natural disasters can significantly disrupt service and create air traffic control problems. These events decrease revenue and can also increase costs. In addition, increases in frequency, severity or duration of thunderstorms, hurricanes, typhoons or other severe weather events, including from changes in the global climate, could result in increases in fuel consumption to avoid such weather, turbulence-related injuries, delays and cancellations, any of which would increase the potential for greater loss of revenue and higher costs. In addition, demand for air travel is typically higher in the June and September quarters, particularly in international markets, because there is more vacation travel during these periods than during the remainder of the year. Because of fluctuations in our results from weather, natural disasters and seasonality, operating results for a historical period are not necessarily indicative of operating results for a future period and operating results for an interim period are not necessarily indicative of operating results for an entire year.

An extended disruption in services provided by our third party regional carriers could have a material adverse effect on our results of operations.

We utilize the services of third party providers in a number of areas in support of our operations that are integral to our business, including third party carriers in the Delta Connection program. While we have agreements with these providers that define expected service performance, we do not have direct control over the operations of these carriers. To the extent that a significant disruption in our regional operations occurs because any of these providers are unable to perform their obligations over an extended period of time, our revenue may be reduced or our expenses may be increased resulting in a material adverse effect on our results of operations.

The failure or inability of insurance to cover a significant liability related to hazards associated with the operation of a refinery by Monroe would have a material adverse effect on our consolidated financial results.

Monroe's refining operations are subject to various hazards unique to refinery operations, including explosions, fires, toxic emissions and natural catastrophes. Monroe's insurance coverage does not cover all potential losses, costs or liabilities and Monroe could suffer losses for uninsurable or uninsured risks or in amounts greater than its insurance coverage. In addition, Monroe's ability to obtain and maintain adequate insurance may be affected by conditions in the insurance market over which it has no control. If Monroe were to incur a significant liability for which it is not fully insured or for which insurance companies do not or are unable to provide coverage, this could have a material adverse effect on our consolidated financial results of operations.

The operation of a refinery by Monroe is subject to significant environmental regulation. Failure to comply with environmental regulations or the enactment of additional regulation could have a negative impact on our consolidated financial results.

Monroe's operations are subject to numerous environmental laws and extensive regulations, including those relating to the discharge of materials into the environment, waste management, pollution prevention measures and greenhouse gas emissions. If Monroe violates or fails to comply with these laws and regulations, Monroe could be fined or otherwise sanctioned, which if significant could have a material adverse effect on our financial results. In addition, the enactment of new environmental laws and regulations, including any laws or regulations relating to greenhouse gas emissions, could significantly increase the level of expenditures required for environmental matters for Monroe.

If we experience losses of senior management personnel and other key employees, our operating results could be adversely affected.

We are dependent on the experience and industry knowledge of our officers and other key employees to execute our business plans. If we experience a substantial turnover in our leadership and other key employees, our performance could be materially adversely impacted. Furthermore, we may be unable to attract and retain additional qualified executives as needed in the future.

Our ability to use net operating loss carryforwards to offset future taxable income for U.S. federal income tax purposes is subject to limitation.

In general, under Section 382 of the Internal Revenue Code of 1986, as amended, a corporation that undergoes an “ownership change” is subject to limitations on its ability to utilize its pre-change net operating losses (“NOLs”), to offset future taxable income. In general, an ownership change occurs if the aggregate stock ownership of certain stockholders (generally 5% shareholders, applying certain look-through rules) increases by more than 50 percentage points over such stockholders' lowest percentage ownership during the testing period (generally three years).

As of December 31, 2012, Delta reported a consolidated federal pretax NOL carryforward of approximately $16.3 billion. Both Delta and Northwest experienced an ownership change in 2007 as a result of their respective plans of reorganization under Chapter 11 of the U.S. Bankruptcy Code. As a result of the merger, Northwest experienced a subsequent ownership change. Delta also experienced a subsequent ownership change on December 17, 2008 as a result of the merger, the issuance of equity to employees in connection with the merger and other transactions involving the sale of our common stock within the testing period.

The Delta and Northwest ownership changes resulting from the merger could limit the ability to utilize pre-change NOLs that were not subject to limitation, and could further limit the ability to utilize NOLs that were already subject to limitation. Limitations imposed on the ability to use NOLs to offset future taxable income could cause U.S. federal income taxes to be paid earlier than otherwise would be paid if such limitations were not in effect and could cause such NOLs to expire unused, in each case reducing or eliminating the benefit of such NOLs. Similar rules and limitations may apply for state income tax purposes. NOLs generated subsequent to December 17, 2008 are not limited.

Risk Factors Relating to the Airline Industry

The airline industry is highly competitive and, if we cannot successfully compete in the marketplace, our business, financial condition and operating results will be materially adversely affected.

The airline industry is highly competitive, marked by significant competition with respect to routes, fares, schedules (both timing and frequency), services, products, customer service and frequent flyer programs. Our domestic operations are subject to competition from both traditional network and discount carriers, some of which may have lower costs than we do and provide service at low fares to destinations served by us. In particular, we face significant competition at our domestic hub airports in Atlanta, Cincinnati, Detroit, Memphis, Minneapolis-St. Paul, New York-LaGuardia, New York-JFK and Salt Lake City either directly at those airports or at the hubs of other airlines that are located in close proximity to our hubs. We also face competition in smaller to medium-sized markets from regional jet operators.

Discount carriers, including Southwest, AirTran (now owned by Southwest), JetBlue, Spirit and Allegiant have placed significant competitive pressure on us in the United States and on other network carriers in the domestic market. In addition, other network carriers have also significantly reduced their costs over the last several years through restructuring and bankruptcy reorganization. American Airlines has recently filed for bankruptcy protection, which may enable it to substantially reduce its costs. Our ability to compete effectively depends, in part, on our ability to maintain a competitive cost structure. If we cannot maintain our costs at a competitive level, then our business, financial condition and operating results could be materially adversely affected.

Our international operations are subject to competition from both domestic and foreign carriers. Through alliance and other marketing and codesharing agreements with foreign carriers, U.S. carriers have increased their ability to sell international transportation, such as services to and beyond traditional European and Asian gateway cities. Similarly, foreign carriers have obtained increased access to interior U.S. passenger traffic beyond traditional U.S. gateway cities through these relationships. In particular, alliances formed by domestic and foreign carriers, including SkyTeam, the Star Alliance (among United, Lufthansa German Airlines, Air Canada and others) and the oneworld alliance (among American Airlines, British Airways, Qantas and others) have significantly increased competition in international markets.

Increased competition has also emerged from well-funded carriers in the Gulf region, including Emirates, Etihad and Qatar. These carriers have large numbers of international widebody aircraft on order and are increasing service to the United States from their hubs in the Middle East. Several of these carriers, along with carriers from China, India and Latin America, are government supported or funded, which has allowed them to grow quickly, reinvest in their product and expand their global presence at the expense of U.S. airlines. In addition, the adoption of liberalized Open Skies Aviation Agreements with an increasing number of countries around the world, including in particular the Open Skies Treaties that the U.S. has with the Member States of the European Union and Japan, could significantly increase competition among carriers serving those markets.

Several joint ventures among U.S. and foreign carriers, including our transatlantic joint venture with Air France-KLM and Alitalia, have received grants of antitrust immunity allowing the participating carriers to coordinate schedules, pricing, sales and inventory. Other joint ventures that have received anti-trust immunity include a transatlantic alliance among United, Air Canada and Lufthansa, a transpacific joint venture among United and All Nippon Airways, a transatlantic joint venture among American Airlines, British Airways and Iberia and a transpacific joint venture between American Airlines and Japan Air Lines.

Consolidation in the domestic airline industry and changes in international alliances have altered and will continue to alter the competitive landscape in the industry by resulting in the formation of airlines and alliances with increased financial resources, more extensive global networks and altered cost structures.

The airline industry is subject to extensive government regulation, and new regulations may increase our operating costs.

Airlines are subject to extensive regulatory and legal compliance requirements that result in significant costs. For instance, the FAA from time to time issues directives and other regulations relating to the maintenance and operation of aircraft that necessitate significant expenditures. We expect to continue incurring expenses to comply with the FAA's regulations.

Other laws, regulations, taxes and airport rates and charges have also been imposed from time to time that significantly increase the cost of airline operations or reduce revenues. The industry is heavily taxed. For example, the Aviation and Transportation Security Act mandates the federalization of certain airport security procedures and imposes security requirements on airports and airlines, most of which are funded by a per ticket tax on passengers and a tax on airlines. The federal government has on several occasions proposed a significant increase in the per ticket tax and has recently proposed additional departure fees. A ticket tax increase or additional fees, if implemented, could negatively impact our results of operations.

Proposals to address congestion issues at certain airports or in certain airspace, particularly in the Northeast United States, have included concepts such as “congestion-based” landing fees, “slot auctions” or other alternatives that could impose a significant cost on the airlines operating in those airports or airspace and impact the ability of those airlines to respond to competitive actions by other airlines. In addition, the failure of the federal government to upgrade the U.S. air traffic control system has resulted in delays and disruptions of air traffic during peak travel periods in certain congested markets. The failure to improve the air traffic control system could lead to increased delays and inefficiencies in flight operations as demand for U.S. air travel increases, having a material adverse effect on our operations. Failure to update the air traffic control system in a timely manner, and the substantial funding requirements of an updated system that may be imposed on air carriers, may have an adverse impact on our financial condition and results of operations.

Events related to extreme weather delays caused the Department of Transportation to promulgate regulations imposing potentially severe financial penalties upon airlines that have flights experiencing extended tarmac delays. These regulations could have a negative impact on our operations in certain circumstances.

Future regulatory action concerning climate change and aircraft emissions could have a significant effect on the airline industry. For example, the European Commission has adopted an emissions trading scheme applicable to all flights operating in the European Union, including flights to and from the United States. If fully implemented, we expect that this system would impose additional costs on our operations in the European Union. Other laws or regulations such as this emissions trading scheme or other U.S. or foreign governmental actions may adversely affect our operations and financial results, either through direct costs in our operations or through increases in costs for jet fuel that could result from jet fuel suppliers passing on increased costs that they incur under such a system.

We and other U.S. carriers are subject to domestic and foreign laws regarding privacy of passenger and employee data that are not consistent in all countries in which we operate. In addition to the heightened level of concern regarding privacy of passenger data in the United States, certain European government agencies are initiating inquiries into airline privacy practices. Compliance with these regulatory regimes is expected to result in additional operating costs and could impact our operations and any future expansion. In addition, a security breach in which passenger or employee data is exposed could result in disruption to our operations, damage to our reputation and significant costs.

Terrorist attacks or international hostilities may adversely affect our business, financial condition and operating results.

The terrorist attacks of September 11, 2001 caused fundamental and permanent changes in the airline industry, including substantial revenue declines and cost increases, which resulted in industry-wide liquidity issues. Potential terrorist attacks or security breaches or fear of such events, even if not made directly on the airline industry, could negatively affect us and the airline industry. The potential negative effects include increased security (including as a result of our global operations), insurance and other costs and lost revenue from increased ticket refunds and decreased ticket sales. Our financial resources might not be sufficient to absorb the adverse effects of any further terrorist attacks or other international hostilities involving the United States.

The rapid spread of contagious illnesses can have a material adverse effect on our business and results of operations.

The rapid spread of a contagious illness can have a material adverse effect on the demand for worldwide air travel and therefore have a material adverse effect on our business and results of operations. Moreover, our operations could be negatively affected if employees are quarantined as the result of exposure to a contagious illness. Similarly, travel restrictions or operational problems resulting from the rapid spread of contagious illnesses in any part of the world in which we operate may have a materially adverse impact on our business and results of operations.

Our insurance costs have increased substantially as a result of the September 11, 2001 terrorist attacks, and further increases in insurance costs or reductions in coverage could have a material adverse impact on our business and operating results.

As a result of the terrorist attacks on September 11, 2001, aviation insurers significantly (1) reduced the maximum amount of insurance coverage available to commercial air carriers for liability to persons (other than employees or passengers) for claims from acts of terrorism, war or similar events and (2) increased the premiums for such coverage and for aviation insurance in general. Since September 24, 2001, the U.S. government has been providing U.S. airlines with war-risk insurance to cover losses, including those resulting from terrorism, to passengers, third parties (ground damage) and the aircraft hull. The U.S. Secretary of Transportation has extended coverage through September 30, 2013, and we expect the coverage to be further extended. The withdrawal of government support of airline war-risk insurance would require us to obtain war-risk insurance coverage commercially, if available. Such commercial insurance could have substantially less desirable coverage than currently provided by the U.S. government, may not be adequate to protect our risk of loss from future acts of terrorism, may result in a material increase to our operating expense or may not be obtainable at all, resulting in an interruption to our operations.

Ground Facilities

We lease most of the land and buildings that we occupy. Our largest aircraft maintenance base, various computer, cargo, flight kitchen and training facilities and most of our principal offices are located at or near the Atlanta airport, on land leased from the City of Atlanta. We own our Atlanta reservations center, other real property in Atlanta and the former Northwest headquarters building and flight training buildings, which are located near the Minneapolis-St. Paul International Airport. Other owned facilities include reservations centers in Minot, North Dakota and Chisholm, Minnesota and a data processing center in Eagan, Minnesota. We also own property in Tokyo, including a 1.3-acre site in downtown Tokyo and a 33-acre land parcel, 512-room hotel and flight kitchen located near Tokyo's Narita International Airport.

We lease ticket counter and other terminal space, operating areas and air cargo facilities in most of the airports that we serve. At most airports, we have entered into use agreements which provide for the non-exclusive use of runways, taxiways and other improvements and facilities; landing fees under these agreements normally are based on the number of landings and weight of aircraft. These leases and use agreements generally run for periods of less than one year to 30 years or more, and often contain provisions for periodic adjustments of lease rates, landing fees and other charges applicable under that type of agreement. We also lease aircraft maintenance facilities and air cargo facilities at certain airports, including, among others: (1) our main Atlanta maintenance base; (2) our Atlanta air cargo facilities; and (3) our hangar and air cargo facilities at the Cincinnati/Northern Kentucky International Airport, Salt Lake City International Airport, Detroit Metropolitan International Airport, Minneapolis-St. Paul International Airport and Seattle-Tacoma International Airport. Our aircraft maintenance facility leases generally require us to pay the cost of providing, operating and maintaining such facilities, including, in some cases, amounts necessary to pay debt service on special facility bonds issued to finance their construction. We also lease marketing, ticketing and reservations offices in certain locations for varying terms.

In recent years, some airports have increased or sought to increase the rates charged to airlines to levels that we believe are unreasonable. The extent to which such charges are limited by statute or regulation and the ability of airlines to contest such charges has been subject to litigation and to administrative proceedings before the DOT. If the limitations on such charges are relaxed, or the ability of airlines to challenge such proposed rate increases is restricted, the rates charged by airports to airlines may increase substantially.

The City of Atlanta is currently implementing portions of a capital improvement program (the “CIP”) at the Atlanta airport. The CIP includes, among other things, a 9,000 foot full-service runway that opened in May 2006, a new international terminal and gate capacity that opened in May 2012, related airfield improvements, new cargo and other support facilities and roadway and other infrastructure improvements.The CIP will not be complete until at least 2014, with individual projects scheduled to be constructed at different times. A combination of federal grants, passenger facility charge revenues, increased user rentals and fees and other airport funds are expected to be used to pay CIP costs directly and through the payment of debt service on bonds. In partnership with the airlines, the airport has initiated the planning of an updated Atlanta airport master plan that is targeted for completion in late 2013 and will define and describe the long-term development plans needed to meet future aviation demand in Atlanta.

During the December 2010 quarter, we began a five-year $1.2 billion redevelopment project at JFK, where we currently operate domestic flights primarily at Terminal 2 and international flights at Terminal 3 and, to a lesser extent, Terminal 4. The expansion and enhancement of Terminal 4, which includes the construction of nine new international gates, commenced in 2011 and is expected to be open in the spring of 2013. Upon completion of the Terminal 4 expansion, we will relocate our operations from Terminal 3 to Terminal 4, proceed with the demolition of Terminal 3 and thereafter conduct coordinated flight operations from Terminals 2 and 4. For information about special project bonds issued to fund a substantial majority of the project and our 30 year sublease of space in Terminal 4 from the operator of Terminal 4, see Note 5 of the Notes to the Consolidated Financial Statements.

In 2012, we expanded our flight operations at New York's LaGuardia Airport in Terminal C, allowing us to accommodate additional flights into LaGuardia. As part of the expansion, we are investing more than $160 million to create an expanded main terminal at LaGuardia in Terminals C and D and have built a bridge to link the two terminals.

In 2012, our wholly-owned subsidiaries, Monroe and MIPC, invested $180 million to acquire the Trainer refinery and related assets from Phillips 66. Monroe received a $30 million grant from the Commonwealth of Pennsylvania. The acquisition includes pipelines and terminal assets that allow the refinery to supply jet fuel to our airline operations throughout the Northeastern U.S., including our New York hubs at LaGuardia and JFK.

ITEM 3. LEGAL PROCEEDINGS

First Bag Fee Antitrust Litigation

In May, June and July, 2009, a number of purported class action antitrust lawsuits were filed in the U.S. District Courts for the Northern District of Georgia, the Middle District of Florida and the District of Nevada against Delta and AirTran Airways (“AirTran”). In these cases, the plaintiffs originally alleged that Delta and AirTran engaged in collusive behavior in violation of Section 1 of the Sherman Act in November 2008 based upon certain public statements made in October 2008 by AirTran's CEO at an analyst conference concerning fees for the first checked bag, Delta's imposition of a fee for the first checked bag on November 4, 2008 and AirTran's imposition of a similar fee on November 12, 2008. The plaintiffs sought to assert claims on behalf of an alleged class consisting of passengers who paid the first bag fee after December 5, 2008 and seek injunctive relief and unspecified treble damages. All of these cases have been consolidated for pre-trial proceedings in the Northern District of Georgia by the Multi-District Litigation (“MDL”) Panel.

In February 2010, the plaintiffs in the MDL proceeding filed a consolidated amended class action complaint which substantially expanded the scope of the original complaint. In the consolidated amended complaint, plaintiffs add new allegations concerning alleged signaling by both Delta and AirTran based upon statements made to the investment community by both carriers relating to industry capacity levels during 2008-2009. Plaintiffs also added a new cause of action against Delta alleging attempted monopolization in violation of Section 2 of the Sherman Act, paralleling a claim previously asserted against AirTran but not Delta.

In August 2010, the District Court issued an order granting Delta's motion to dismiss the Section 2 claim, but denying its motion to dismiss the Section 1 claim. Plaintiffs have filed a motion to certify the Section 1 class, which remains pending. Delta believes the claims in these cases are without merit and is vigorously defending these lawsuits.

EU Regulation 261 Class Action Litigation

In February 2011, a putative class action was filed in the U.S. District Court for the Northern District of Illinois seeking to represent all US residents who were passengers on flights during the period from February 2009 to the present who are allegedly entitled to compensation under EU Regulation 261 because their flight was cancelled or delayed by more than 3 hours. Plaintiffs allege that Delta has incorporated a duty to pay this compensation into its contract of carriage, and assert a claim for breach of contract as the basis for their cause of action. The complaint seeks recovery of the EU Regulation 261 compensation of €600 for each US resident on a flight qualifying for such compensation. Delta disputes the allegations in the Complaint, has filed a motion to dismiss all claims and intends to vigorously defend the matter.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Financial Highlights - 2012 Compared to 2011

Our net income for 2012 was $1.0 billion, or $1.19 per diluted share. Total operating revenue increased $1.6 billion, or 4%, over 2011, primarily due to higher passenger revenue due to yield improvement. Fuel expense, including our contract carriers under capacity purchase agreements, increased due to a 6% increase in our average price per gallon, despite a 2% decrease in consumption.

Passenger revenue increased $1.6 billion due to a 5% year over year improvement in passenger mile yield on flat traffic, while capacity declined 2%. Passenger revenue per available seat mile ("PRASM") increased 7% over 2011, reflecting higher revenue under corporate travel contracts and improvements in our products and services.

Total operating expense increased $1.4 billion over 2011, driven primarily by higher fuel expense and salaries and related costs. Our fuel expense increased $468 million (including our contract carriers under capacity purchase agreements) compared to 2011 due to a 6% increase in our average price per gallon, despite a 2% decrease in consumption. During 2012, we recorded losses of $66 million due to changes in the fair value of our fuel hedge portfolio. Excluding mark-to-market adjustments recorded in periods other than the settlement period ("MTM adjustments"), our average fuel price for the year was $3.26 per gallon, compared to $3.05 per gallon for 2011.

Our consolidated operating cost per available seat mile ("CASM") for 2012 increased 6% to $14.97 cents, primarily reflecting increased fuel price. For 2012, CASM-Ex was $8.92 cents, or 5% higher than 2011. The non-GAAP financial measures used in this section are defined in "Supplemental Information" below.

Company Initiatives

Strengthening the Balance Sheet

We will continue to focus on cash flow generation with the goal of further strengthening our balance sheet. We finished 2012 with $5.2 billion in unrestricted liquidity (consisting of cash, cash equivalents, short-term investments and undrawn revolving credit facility capacity). During 2012, we generated $2.5 billion in cash from operating activities, and reduced debt by $1.1 billion and funded capital expenditures while maintaining a solid liquidity position.

Structural Cost Initiatives

We implemented a $1 billion structural cost initiatives program. These initiatives are designed to improve our cost efficiency while maintaining our operational performance and revenue generation and include:

•Domestic fleet restructuring to retire older, less efficient aircraft from our fleet;

•Maintenance redesign focusing on improving our processes and resource management;

•Distribution platforms to increase the use of cost effective and value-added distribution channels such as delta.com;

•Staffing efficiency to generate higher productivity levels through technology and improved staffing models; and

•Other costs to improve network efficiency and to reduce transportation expense.

We anticipate realizing the benefits of the structural cost initiatives in 2013, with CASM-Ex growth moderating in the second half of 2013, and the benefits of the initiatives increasing through 2015.

Domestic Fleet Restructuring

Domestic fleet restructuring is a key part of our structural cost initiatives, and is focused on lowering unit costs while investing in our fleet to enhance the customer experience. We are restructuring our domestic fleet by reducing our 50-seat regional flying and replacing other older, less cost effective aircraft with newer, more efficient aircraft. Recent agreements with SkyWest Airlines, Inc., Pinnacle Airlines, Inc. and Bombardier Aerospace have produced a path for us to eliminate more than 200 50-seat aircraft. We are replacing these aircraft and older B-757-200 aircraft with more efficient and customer preferred CRJ-900, B-717-200 and B-737-900ER aircraft.

In 2012, we entered into an agreement with Bombardier Aerospace to purchase 40 CRJ-900 aircraft with 12 deliveries this year and 28 in 2014. Also in 2012, we finalized agreements with Southwest Airlines and The Boeing Company ("Boeing") to lease 88 B-717-200 aircraft. Delivery of the aircraft will begin later this year, with 16 aircraft scheduled to enter our fleet. We will receive 36 aircraft deliveries in each of 2014 and 2015. These B-717-200 aircraft are 110-seat aircraft and will feature new, fully upgraded interiors, with 12 First Class seats, 15 Economy Comfort seats and in-flight WiFi throughout the cabin.

In 2011, we entered into an agreement with Boeing to purchase 100 new fuel efficient B-737-900ER aircraft. We will add these aircraft to our fleet between this year and 2018, primarily replacing older B-757-200 aircraft. We expect the B-737-900ER to offer an industry leading customer experience, including expanded carry-on baggage space and a spacious cabin. Additionally, we continue to increase our MD-90 fleet with previously owned aircraft that offer a lower total cost of ownership.

As we restructure our fleet and assess our fleet plans, we will continue to evaluate older, retiring aircraft and related equipment for changes in depreciable life, impairment and lease termination costs. By 2015, we expect to reduce our 50-seat aircraft fleet to 125 aircraft. The associated retirement of aircraft will result in material lease termination and other charges over this period. We expect to benefit from reduced future maintenance cost and improved operational and fuel efficiency that we will experience over the life of the new aircraft.

Oil Refinery Acquisition

Jet fuel costs have continued to increase in recent years, making fuel expense our single largest expense. Because global demand for jet fuel and related products is increasing at the same time that jet fuel refining capacity is decreasing in the U.S. (particularly in the Northeast), the refining margin reflected in the prices we pay for jet fuel has increased. We purchased an oil refinery as part of our strategy to mitigate the increasing cost of the refining margin we are paying.

Acquisition

In June 2012, Monroe acquired the Trainer refinery and related assets located near Philadelphia, Pennsylvania from Phillips 66, which had shut down operations at the refinery. Monroe invested $180 million to acquire the refinery. Monroe received a $30 million grant from the Commonwealth of Pennsylvania. The acquisition includes pipelines and terminal assets that will allow the refinery to supply jet fuel to our airline operations throughout the Northeastern U.S., including our New York hubs at LaGuardia and JFK.

Because the products and services of Monroe's refinery operations are discrete from our airline services, segment results are prepared for our airline segment and our refinery segment. Financial information on our segment reporting can be found in Note 2 of the Notes to the Consolidated Financial Statements.

Refinery Operations and Strategic Agreements

The facility is capable of refining 185,000 barrels of crude oil per day. BP is the primary supplier of crude oil used by the refinery under a three year agreement. We are also exploring other sources of crude oil supply, such as bringing supply to the refinery by rail from the Bakken oil field in North Dakota. We have increased the refinery's jet fuel capacity through capital improvements. The refinery's remaining production consists of gasoline, diesel and refined products ("non-jet fuel products"). Under a multi-year agreement, we are exchanging a significant portion of the non-jet fuel products with Phillips 66 for jet fuel to be used in our airline operations. Substantially all of the remaining production of non-jet fuel products is being sold to BP under a long-term buy/sell agreement effectively exchanging those non-jet fuel products for jet fuel. Our agreement with Phillips 66 requires us to deliver specified quantities of non-jet fuel products and they are required to deliver jet fuel to us. If we or Phillips 66 do not have the specified quantity and type of product available, the delivering party is required to procure any such shortage to fulfill its obligation under the agreement. Substantially all of the refinery's expected production of non-jet fuel products is included in these agreements.

Refinery Start-Up

During the December 2012 quarter, fuel production increased at the refinery. However, Superstorm Sandy negatively impacted the refinery start up, slowing production and lowering efficiency levels. The refinery recorded a $63 million net loss for the quarter.

New York Strategy

Strengthening our position in New York City continues to be an important part of our network strategy. As discussed below, key components of this strategy are operating a domestic hub at LaGuardia and creating a state-of-the-art facility at JFK. In May 2012, we announced new and expanded service to 10 popular leisure destinations (in addition to the service expansion discussed below) in the Caribbean, Bermuda and Florida from LaGuardia and JFK. These flights began operating in the December quarter of 2012.

LaGuardia. During December 2011, we closed transactions with US Airways where we received takeoff and landing rights (each a "slot pair") at LaGuardia in exchange for slot pairs at Reagan National. This exchange allows us to operate a new domestic hub at LaGuardia. We have increased capacity at LaGuardia by 42% since March 2012, adding 100 new flights and a total of 26 new destinations. The first phase of new flights began on March 25 and the second phase commenced on July 11. We currently operate about 260 daily flights between LaGuardia and 60 cities, more than any other airline.

We are also investing more than $160 million in a renovation and expansion project at LaGuardia to enhance the customer experience. In December 2012, we opened the connector linking Terminals C and D and in September 2012 we opened a new SkyClub in Terminal C. Ongoing investments include expanded security lanes and a baggage handling system in both terminals as well as an expanded SkyClub in Terminal D.

JFK. While our expanded LaGuardia schedule is focused on providing industry-leading domestic service, we are optimizing our international and trans-continental flight schedule at JFK to facilitate convenient connections for our passengers and improve coordination with our SkyTeam alliance partners.

At JFK, we currently operate domestic flights primarily at Terminal 2 and international flights at Terminal 3 and, to a lesser extent, Terminal 4. Our five-year $1.2 billion renovation project at JFK, which began in 2010, is on schedule. The expansion and enhancement of Terminal 4, which includes the construction of nine new international gates, is expected to be open in the spring of 2013. Upon completion of the Terminal 4 expansion, we will relocate our operations from Terminal 3 to Terminal 4, proceed with the demolition of Terminal 3 and thereafter conduct coordinated flight operations from Terminals 2 and 4. Once our project is complete, we expect that passengers will benefit from an enhanced customer experience and improved operational performance, including reduced taxi times and better on-time performance.

Alliances and Equity Investments

We have made long-term investments in other airlines that give us the ability to increase our network scale and produce revenue improvements. We invested in GOL and Aeromexico because they operate in Latin America's two largest markets, Brazil and Mexico, respectively. Pending regulatory approval, we also agreed to buy 49% of Virgin Atlantic, currently held by Singapore Airlines, for $360 million. We also entered into a joint venture agreement with Virgin Atlantic with respect to operations on non-stop routes between the United Kingdom and North America. We and Virgin Atlantic will file an application with the U.S. Department of Transportation for U.S. antitrust immunity with respect to the joint venture.

Pilot Agreement

During the June 2012 quarter, we reached an agreement with the Air Line Pilots Association, International (“ALPA”) to modify the existing collective bargaining agreement covering Delta’s pilots. The agreement, which was ratified by the pilots in June 2012, provides career growth opportunities as well as pay and benefits improvements for our pilots including increases to base pay and changes to our profit sharing program. The agreement, which becomes amendable on December 31, 2015, will also provide Delta with productivity gains and support our domestic fleet restructuring.

Passenger Revenue. Passenger revenue increased $1.6 billion, or 5%, due to an improvement in the passenger mile yield of 5%, on a 2% decline in capacity. Passenger mile yield and unit revenue increased due to fare increases, higher revenue under corporate travel contracts and improvements in our products and services.

International mainline passenger revenue increased $520 million. In early 2011, we faced industry overcapacity in the transatlantic market and in connection with our joint venture partners, AirFrance-KLM and Alitalia, we reduced capacity in underperforming markets during the second half of 2011 and in 2012. As a result, Atlantic PRASM was up 9%, driven by a 5% increase in yield on a 7% decrease in capacity. Pacific passenger revenue increased 10% on a 3% and 6% increase in capacity and traffic, respectively. These results reflect Pacific market improvement, as demand returned to levels seen prior to the March 2011 earthquake and tsunami in Japan. Latin America passenger revenue increased 8% on a 3% and 6% increase in capacity and traffic, respectively.

Fuel Expense. Including contract carriers under capacity purchase agreements, fuel expense increased $468 million because of a 6% increase in our average price per gallon, despite a 2% decrease in consumption. The table below presents fuel expense, gallons consumed and our average price per gallon, including the impact of fuel hedge losses of $66 million during the year ended December 31, 2012:

Fuel Purchase Cost. Fuel purchase cost is based on the market price for jet fuel at airport locations.

Refinery Impact. The refinery results include the impact on fuel expense of self-supply from the production of the refinery and from refined products exchanged with Phillips 66 and BP. As described in Note 2 of the Notes to the Consolidated Financial Statements, to the extent that we account for exchanges of refined products as non-monetary transactions, we include the results of those transactions within fuel expense.

Fuel Hedge Losses (Gains) and MTM Adjustments. During the year ended December 31, 2012, our fuel hedge losses of $66 million included $27 million of MTM adjustments. These MTM adjustments are based on market prices as of the end of the reporting period for contracts settling in future periods. Such market prices are not necessarily indicative of the actual future value of the underlying hedge in the contract settlement period. The losses for MTM adjustments are reflected in the table above to calculate an effective fuel cost for the period.

We adjust fuel expense for these items to arrive at a more meaningful measure of fuel cost. Our average price per gallon, adjusted (a non-GAAP financial measure as defined in "Supplemental Information" below) was $3.26 for the year ended December 31, 2012.

Salaries and Related Costs. The increase in salaries and related costs is primarily due to employee pay increases, increases in pension expense and other benefits.

During the June 2012 quarter, we reached an agreement with ALPA that increases pay and benefits for our pilots. Our pilots and substantially all other employees received base pay increases on July 1, 2012 and received additional increases on January 1, 2013. These increases are designed both to recognize changes to the profit sharing program described below and to accelerate the planned 2013 pay increase for non-pilot employees.

Aircraft Maintenance Materials and Outside Repairs. Aircraft maintenance materials and outside repairs consists of costs associated with maintenance of aircraft used in our operations and maintenance sales to third parties by our MRO services business. The increase in maintenance costs is primarily due to the cyclical timing of maintenance events on our fleet. Additionally, maintenance cost increased as we accelerated certain maintenance events into 2012, resulting in a lower total cost for those activities, and completed maintenance initiatives to improve our operational reliability.

Passenger Commissions and Other Selling Expenses. The decrease in passenger commissions and other selling expenses is primarily due to lower booking fees and international commission rates, partially offset by increases in sales.

Contracted Services. Contracted services expense decreased year-over-year due primarily to the impact of severe winter storms on our operations in the March 2011 quarter.

Profit Sharing. Our broad based employee profit sharing program provides that, for each year in which we have an annual pre-tax profit, as defined by the terms of the program, we will pay a specified portion of that profit to employees. In determining the amount of profit sharing, the terms of the program specify the exclusion of special items, such as MTM adjustments and restructuring and other items, from pre-tax profit. During the June 2012 quarter, our profit sharing program was modified so that we will pay 10% of profits on the first $2.5 billion of annual profits effective with the plan year beginning January 1, 2013 compared to paying 15% of annual profits for the 2012 plan year. Under the program, we will continue to pay 20% of annual profits above $2.5 billion.

Restructuring and Other Items. Due to the nature of amounts recorded within restructuring and other items, a year-over-year comparison is not meaningful. For a discussion of charges recorded in restructuring and other items, see Note 16 of the Notes to the Consolidated Financial Statements.

Mainline Passenger Revenue. Mainline passenger revenue increased primarily due to an improvement in the passenger mile yield from fare increases implemented in response to higher fuel prices and from higher revenue under corporate travel contracts.


•	Domestic. Domestic mainline passenger revenue increased 11% due to an 11% improvement in PRASM on a 1% decline in capacity. The improvement in PRASM reflects higher passenger mile yield driven by fare increases.

•

International. International mainline passenger revenue increased 13% due to a 9% improvement in PRASM on a 4% capacity increase. Passenger mile yield increased 12%, reflecting increased business and leisure travel and increased fares, including fuel surcharges. Atlantic passenger revenue increased 9% due to a 7% increase in PRASM. We and the industry faced overcapacity in the Atlantic, particularly in early 2011, which prevented us from increasing ticket prices sufficiently to cover higher fuel prices. Pacific passenger revenue increased 20% on a 10% capacity increase. Pacific passenger mile yield increased 15% due to a stronger revenue environment, partially offset by the negative impact from the March 2011 earthquake and tsunami in Japan. Latin America passenger revenue increased 13%, benefiting from a 13% higher passenger mile yield driven by fare increases.

Regional carriers. Passenger revenue from regional carriers increased 9% due to an 12% improvement in PRASM on a 2% decline in capacity. Passenger mile yield increased 12%, reflecting fare increases we implemented in response to increased fuel prices.

Cargo. Cargo revenue increased 21% due to a 12% improvement in yield and an 8% increase in volume.

Other. Other revenue increased $210 million due to higher maintenance sales to third parties by our MRO services business and $65 million due to an increase in the volume of ticket change fees. These increases were partially offset by $90 million in lower baggage fee revenue, resulting from an increase in bag fees waived for premium customers and customers under our co-brand credit card agreement with American Express.

On July 1, 2010, we sold Compass and Mesaba, our wholly-owned subsidiaries, to Trans States and Pinnacle, respectively. Upon the closing of these transactions, we entered into new or amended long-term capacity purchase agreements with Compass, Mesaba and Pinnacle. Prior to these sales, expenses related to Compass and Mesaba as our wholly-owned subsidiaries were reported in the applicable expense line items. Subsequent to these sales, expenses related to Compass and Mesaba are reported as contract carrier arrangements expense.

Fuel Expense. Including contract carriers under capacity purchase agreements, fuel expense increased $2.9 billion on flat consumption. The table below presents fuel expense, gallons consumed and our average price per gallon, including the impact of fuel hedge activity:



	Year Ended December 31,				Increase		% Increase
(in millions, except per gallon data)	2011		2010		Increase		% Increase
Aircraft fuel and related taxes	$	9,730	$	7,594	$	2,136

Total fuel consumption (gallons)	3,856		3,823		33		1	%
Average price per gallon	$	3.06	$	2.33	$	0.73	31	%

Fuel expense increased primarily due to higher unhedged fuel prices, partially offset by an improvement in net fuel hedge results. The table below shows the impact of hedging on fuel expense and average price per gallon:



									Average Price Per Gallon
	Year Ended December 31,					Increase (Decrease)			Year Ended December 31,					Increase (Decrease)

Total fuel expense, adjusted	$	11,757		$	8,901	$	2,856		$	3.05		$	2.33	$	0.72

Our average price per gallon, adjusted for MTM adjustments for fuel hedges recorded in periods other than the settlement period (a non-GAAP financial measure as defined in "Supplemental Information" below) was $3.05 for the year ended December 31, 2011. During 2011, our net fuel hedge gains of $420 million included $26 million of MTM adjustments recorded in periods other than the settlement period.

Salaries and Related Costs. Salaries and related costs increased due to a 3% average increase in headcount and employee pay increases, partially offset by the change in reporting described above due to the transactions involving Compass and Mesaba.

Contract Carrier Arrangements. Contract carrier arrangements expense, excluding the impact of fuel expense (discussed above), increased primarily due to the change in reporting for the transactions involving Compass and Mesaba.

Aircraft Maintenance Materials and Outside Repairs. Aircraft maintenance materials and outside repairs expense increased primarily due to costs associated with increased maintenance sales to third parties by our MRO services business, reflected in other revenue above.

Passenger Commissions and Other Selling Expenses. Credit card and sales commissions increased in conjunction with the 11% increase in passenger revenue.

Aircraft Rent. Aircraft rent decreased primarily due to the restructuring of certain existing leases and the change in reporting described above due to the transactions involving Compass and Mesaba.

Restructuring and Other Items. Due to the nature of amounts recorded within restructuring and other items, a year-over-year comparison is not meaningful. For a discussion of charges recorded in restructuring and other items, see Note 16 to the Notes of the Consolidated Financial Statements.

During the years ended December 31, 2012, 2011 and 2010, we recorded $118 million, $68 million and $391 million in losses from the early extinguishment of debt, which primarily related to the write-off of debt discounts. These debt discounts are a result of fair value adjustments recorded in 2008 to reduce the carrying value of our long-term debt due to purchase accounting and a $1.0 billion advance purchase of SkyMiles by American Express. As a result of these write-offs and scheduled amortization, our unamortized debt discount has decreased from $1.4 billion at the beginning of 2010 to $527 million at December 31, 2012.

Income Taxes

We consider all income sources, including other comprehensive income, in determining the amount of tax benefit allocated to continuing operations. During the three years ended December 31, 2012, we did not record an income tax provision for U.S. federal income tax purposes since our deferred tax assets are fully reserved by a valuation allowance. The following table shows the components of our income tax (provision) benefit:



	Year Ended December 31,
(in millions)	2012			2011			2010
International and state income tax benefit (provision)	$	1		$	(7	)	$	(15	)
Deferred tax (provision) benefit	(17		)	2			—
Alternative minimum tax refunds and other	—			90			—
Income tax (provision) benefit	$	(16	)	$	85		$	(15	)

During 2011, we recorded an income tax benefit of $85 million, primarily related to the recognition of alternative minimum tax refunds.

At December 31, 2012, we had $16.3 billion of U.S. federal pre-tax net operating loss carryforwards. Accordingly, we believe we will not pay any cash federal income taxes during the next several years. Our U.S. federal pre-tax net operating loss carryforwards do not begin to expire until 2022.

Financial Condition and Liquidity

We expect to meet our cash needs for the next 12 months from cash flows from operations, cash and cash equivalents, short-term investments and financing arrangements. As of December 31, 2012, we had $5.2 billion in unrestricted liquidity, consisting of $3.4 billion in cash and cash equivalents and short-term investments and $1.8 billion in undrawn revolving credit facilities.

Sources of Liquidity

Operating Cash Flow

Cash flows from operating activities continue to provide our primary source of liquidity. We generated positive cash flows from operations of $2.5 billion in 2012 and $2.8 billion in each of 2011 and 2010. See below under "Timing of SkyMiles Sales" for a discussion of the variances in 2012 and 2011 cash flows from operating activities compared to the preceding years. We expect to generate positive cash flows from operations in 2013.

Our operating cash flows can be impacted by the following factors:

Seasonality of Advance Ticket Sales. We sell tickets for air travel in advance of the customer's travel date, and receive cash payment at the time of sale. As a result, we record the cash received on advance sales as deferred revenue in Air Traffic Liability. The Air Traffic Liability increases during the spring as we have increased sales in advance of the summer peak travel season. Our cash balances are typically higher at the beginning of the summer and at a low point during the winter.

Fuel and Fuel Hedge Margins. The cost of jet fuel is our most significant expense, representing approximately 36% of our total operating expenses. The market price for jet fuel is highly volatile and can vary significantly from period to period. This price volatility affects our cash flows from operations, impacting comparability from period to period.

We have jet fuel inventories at various airport locations, which are used in our airline operations. Also, we acquired the Trainer oil refinery in 2012, which, as part of refinery operations, has refined oil product inventories. Jet fuel and refined oil product inventories are recorded as Fuel Inventory. Fuel Inventory increased during 2012 as a result of the start up of refinery operations in the September quarter and the transition of our fuel supply program. The increase in Fuel Inventory to achieve normal operating levels at our refinery was offset by a similar increase in accounts payable, and therefore, did not have a significant impact on operating cash flows during 2012. The remaining $180 million increase in Fuel Inventory was a result of the transition in Delta's fuel supply program.

As part of our fuel hedging program, we may be required to pay hedge margin to counterparties when our portfolio is in a loss position. Conversely, if our portfolio with counterparties is in a gain position, we may receive hedge margin. Our future cash flows are impacted depending upon the nature of our derivative contracts and the market price of the commodities underlying our derivative contracts

Timing of SkyMiles Sales. In December 2011, we amended our American Express agreements and agreed to sell $675 million of unrestricted SkyMiles to American Express in each December from 2011 through 2014. Under the December 2011 amendment, American Express purchased $675 million of unrestricted SkyMiles in both 2012 and 2011. In 2011, this operating cash flow was largely offset by working capital changes. We anticipate American Express will make additional purchases of $675 million of unrestricted SkyMiles in both 2013 and 2014.

In 2008, we entered into a multi-year extension of our American Express agreements and received $1.0 billion from American Express for an advance purchase of restricted SkyMiles. The 2008 agreement provided that our obligations with respect to the advance purchase would be satisfied as American Express uses the purchased miles over a specified future period (“SkyMiles Usage Period”). During the SkyMiles Usage Period, which commenced in December 2011, American Express draws down SkyMiles valued at $333 million annually over three years beginning 2012 instead of paying cash to Delta for SkyMiles used. This draw down of $333 million in SkyMiles reduced cash flows from operations in 2012 compared to 2011 and 2010.

Pension Contributions. We sponsor defined benefit pension plans for eligible employees and retirees. These plans are closed to new entrants and are frozen for future benefit accruals. Our funding obligations for these plans are governed by the Employee Retirement Income Security Act, as modified by the The Pension Protection Act of 2006. We contributed $697 million and $598 million to our defined benefit pension plans during 2012 and 2011, respectively. We estimate the funding requirements under these plans will total approximately $675 million in 2013.

Undrawn Lines of Credit

Delta has available $1.8 billion in undrawn lines of credit. As described in Note 8 of the Notes to the Consolidated Financial Statements, we have an undrawn $1.2 billion first-lien revolving credit facility, as part of our 2011 Credit Facilities. The revolving credit facility carries a variable interest rate and expires in April 2016.

We also have an undrawn $450 million revolving credit facility included in the 2012 Pacific Facilities, as described in Note 8 of the Notes to the Consolidated Financial Statements. The 2012 Pacific Facilities are secured by our Pacific routes and slots, as described in Note 6 of the Notes to the Consolidated Financial Statements. This revolving credit facility carries a variable interest rate and expires in October 2017. In addition, we have an undrawn bank revolving credit facility of $150 million.

The credit facilities mentioned above have covenants, such as collateral coverage ratios. If we are not in compliance with these covenants, we must repay amounts borrowed under the credit facilities and may not be able to draw on the revolving credit facilities. Our ability to obtain additional financing, if needed, on acceptable terms could be adversely affected by the fact that a significant portion of our assets are subject to liens.

Investing and Financing

Capital Expenditures

We incurred capital expenditures of $2.0 billion in 2012 and $1.3 billion in each of 2011 and 2010. Our capital expenditures were primarily for the purchase of aircraft and aircraft modifications that upgraded aircraft interiors and are enhancing our product offering.

We have committed to future aircraft purchases that will require significant capital investment, and have obtained long-term financing commitments for a substantial portion of the purchase price of these aircraft. We expect that we will invest more than $2 billion in 2013 primarily for aircraft, aircraft modifications and the purchase of a $360 million equity investment in Virgin Atlantic. The 2013 investments will be funded through cash from operations and new financings.

Financings

At December 31, 2012, total debt and capital leases, including current maturities, was $12.7 billion, a $1.1 billion reduction from December 31, 2011 and a $2.5 billion reduction from December 31, 2010. We have focused on reducing our total debt over the past three years as part of our strategy to strengthen our balance sheet. In addition, we have refinanced previous financing transactions, which we expect to reduce our total future interest expense.

In 2012, we received $480 million in proceeds secured by aircraft previously financed by debt. In 2012, we also refinanced $1.7 billion in debt and undrawn revolving credit facilities secured by our Pacific routes and slots, which resulted in a lower interest rate. We expect the Pacific routes and slots refinancing transaction will generate more than $30 million in annual interest expense savings.

Contractual Obligations

The following table summarizes our contractual obligations at December 31, 2012 that we expect will be paid in cash. The table does not include amounts that are contingent on events or other factors that are uncertain or unknown at this time, including legal contingencies, uncertain tax positions and amounts payable under collective bargaining arrangements, among others. In addition, the table does not include expected significant cash payments which are generally ordinary course of business obligations that do not include contractual commitments.

The amounts presented are based on various estimates, including estimates regarding the timing of payments, prevailing interest rates, volumes purchased, the occurrence of certain events and other factors. Accordingly, the actual results may vary materially from the amounts presented in the table.

During 2012, our contractual obligations were impacted by our agreement with Bombardier to purchase 40 CRJ-900 aircraft with deliveries beginning in 2013 and continuing through 2014 and with our agreement with Pinnacle Airlines, Inc. to purchase 16 CRJ-900 aircraft with deliveries in 2013. Our estimated payments to purchase these aircraft are included in the obligations below. In addition, we entered into agreements with Southwest Airlines and The Boeing Company to lease 88 B-717-200 aircraft with deliveries beginning in 2013 and continuing through 2015.

⁽²⁾	Includes $360 million in 2013 related to our agreement to buy, pending regulatory approval, 49% of Virgin Atlantic, currently held by Singapore Airlines.

Long-Term Debt, Principal Amount. Represents scheduled principal payments on long-term debt. The table excludes amounts received from American Express for its advance purchase of restricted SkyMiles because this obligation will be satisfied by American Express' use of SkyMiles over a specified period rather than by cash payments from us. For additional information about our agreements with American Express, see Note 7 of the Notes to the Consolidated Financial Statements.

Long-Term Debt, Interest Payments. Represents estimated interest payments under our long-term debt based on the interest rates specified in the applicable debt agreements. Interest payments on variable interest rate debt were calculated using LIBOR at December 31, 2012.

Contract Carrier Obligations. Represents our estimated minimum fixed obligations under capacity purchase agreements with regional carriers. The reported amounts are based on (1) the required minimum levels of flying by our contract carriers under the applicable agreements and (2) assumptions regarding the costs associated with such minimum levels of flying.

Employee Benefit Obligations. Represents primarily (1) our estimated minimum required funding for our qualified defined benefit pension plans based on actuarially determined estimates and (2) projected future benefit payments from our unfunded postretirement and postemployment plans. For additional information about our employee benefit obligations, see “Critical Accounting Policies and Estimates”.

Aircraft Purchase Commitments. Represents primarily our commitments to purchase 100 B-737-900ER aircraft, 18 B-787-8 aircraft, 56 CRJ-900 aircraft and four previously owned MD-90 aircraft. Our purchase commitment for 18 B-787-8 aircraft provides for certain aircraft substitution rights.

Other Obligations. Represents estimated purchase obligations under which we are required to make minimum payments for goods and services, including but not limited to insurance, marketing, maintenance, technology, sponsorships and other third party services and products. Additionally, other obligations includes estimates of lease payments that will be made under agreements entered into in 2012 with Southwest Airlines and The Boeing Company to lease 88 B-717-200 aircraft with deliveries beginning in 2013 and continuing through 2015.

Critical Accounting Policies and Estimates

Our critical accounting policies and estimates are those that require significant judgments and estimates. Accordingly, the actual results may differ materially from these estimates. For a discussion of these and other accounting policies, see Note 1 of the Notes to the Consolidated Financial Statements.

Frequent Flyer Program

Our frequent flyer program (the “SkyMiles Program”) offers incentives to travel on Delta. This program allows customers to earn mileage credits by flying on Delta, regional air carriers with which we have contract carrier agreements and airlines that participate in the SkyMiles Program, as well as through participating companies such as credit card companies, hotels and car rental agencies. We also sell mileage credits to non-airline businesses, customers and other airlines.

The SkyMiles Program includes two types of transactions that are considered revenue arrangements with multiple deliverables. As discussed below, these are (1) passenger ticket sales earning mileage credits and (2) the sale of mileage credits to participating companies with which we have marketing agreements. Mileage credits are a separate unit of accounting as they can be redeemed by customers in future periods for air travel on Delta and participating airlines, membership in our Sky Club and other program awards.

Passenger Ticket Sales Earning Mileage Credits. Passenger ticket sales earning mileage credits under our SkyMiles Program provide customers with two deliverables: (1) mileage credits earned and (2) air transportation. We value each deliverable on a standalone basis. Our estimate of the standalone selling price of a mileage credit is based on an analysis of our sales of mileage credits to other airlines and customers and is re-evaluated at least annually. We use established ticket prices to determine the standalone selling price of air transportation. We allocate the total amount collected from passenger ticket sales between the deliverables based on their relative selling prices.

We defer revenue for the mileage credits related to passenger ticket sales and recognize it as passenger revenue when miles are redeemed and services are provided. We record the air transportation portion of the passenger ticket sales in air traffic liability and recognize these amounts in passenger revenue when we provide transportation or when the ticket expires unused. A hypothetical 10% increase in our estimate of the standalone selling price of a mileage credit would decrease passenger revenue by approximately $50 million, as a result of an increase in the amount of revenue deferred from the mileage component of passenger ticket sales.

Sale of Mileage Credits. Customers may earn mileage credits through participating companies such as credit card companies, hotels and car rental agencies with which we have marketing agreements to sell mileage credits. Our contracts to sell mileage credits under these marketing agreements have two deliverables: (1) the mileage credits redeemable for future travel and (2) the marketing component.

Our most significant contract to sell mileage credits relates to our co-brand credit card relationship with American Express. We defer revenue related to the mileage credits sold to American Express based on prices at which we sell mileage credits to other airlines, and re-evaluate our deferral rate at least annually. We allocate an amount to the marketing component in an amount equal to the excess of the amount received over the mileage component. Under this approach (the "residual method”), the deferred revenue from the mileage component is recognized as passenger revenue when miles are redeemed and services are provided, while the portion of the revenue related to the marketing component is recognized as those marketing services are provided. We will continue to use the residual method until our contract with American Express is materially modified. If we materially modify this agreement, we will then be required to allocate the consideration received to the marketing and the mileage components based upon their relative selling prices (“relative selling price method”). A material modification of this contract and the resultant change from the residual method to the relative selling price method could impact our deferral rate or cause an adjustment to our deferred revenue balance, which could materially impact our future financial results.

Breakage. For mileage credits which we estimate are not likely to be redeemed (“breakage”), we recognize the associated value proportionally during the period in which the remaining mileage credits are expected to be redeemed. Management uses statistical models to estimate breakage based on historical redemption patterns. A change in assumptions as to the period over which mileage credits are expected to be redeemed, the actual redemption activity for mileage credits or the estimated fair value of mileage credits expected to be redeemed could have a material impact on our revenue in the year in which the change occurs and in future years. At December 31, 2012, the aggregate deferred revenue balance associated with the SkyMiles Program was $4.4 billion. A hypothetical 1% change in the number of outstanding miles estimated to be redeemed would result in a $30 million impact on our deferred revenue liability at December 31, 2012.

Goodwill and Indefinite-Lived Intangible Assets

We assess our goodwill and indefinite-lived intangible assets under a qualitative or quantitative approach. Under a qualitative approach, we consider many market factors, including those listed under Key Assumptions below. We analyze these market factors to determine if events and circumstances have affected the fair value of goodwill and indefinite-lived intangible assets. If we determine that it is more likely than not that the asset value may be impaired, we use the quantitative approach to assess the asset's fair value and the amount of the impairment. Under a quantitative approach, we calculate the fair value of the asset using the Key Assumptions listed below. If the asset's carrying value exceeds its fair value calculated using the quantitative approach, we will record an impairment charge for the difference in fair value and carrying value.

When we evaluate goodwill for impairment using a quantitative approach, we estimate the fair value of the reporting unit by considering market capitalization and other factors. When we perform a quantitative impairment assessment of our indefinite-lived intangible assets, fair value is estimated based on (1) recent market transactions, where available, (2) a combination of limited market transactions and the lease savings method for certain airport slots (which reflects potential lease savings from owning the slots rather than leasing them from another airline at market rates), (3) the royalty method for the Delta tradename (which assumes hypothetical royalties generated from using our tradename) or (4) projected discounted future cash flows (an income approach).

Key Assumptions. The key assumptions in our impairment tests include (1) our projected revenues, expenses and cash flows, (2) an estimated weighted average cost of capital, (3) assumed discount rates depending on the asset and (4) a tax rate. These assumptions are consistent with those hypothetical market participants would use. Since we are required to make estimates and assumptions when evaluating goodwill and indefinite-lived intangible assets for impairment, the actual amounts may differ materially from these estimates. In addition, we consider the amount the intangible assets' fair value exceeded their carrying value in the most recent fair value measurement using a quantitative approach.

Changes in certain events and circumstances could result in impairment. Factors which could cause impairment include, but are not limited to, (1) negative trends in our market capitalization, (2) an increase in fuel prices, (3) declining passenger mile yields, (4) lower passenger demand as a result of a weakened U.S. and global economy, (5) interruption to our operations due to an employee strike, terrorist attack, or other reasons and (6) changes to the regulatory environment.

We assessed each of the above assumptions in our most recent impairment analyses. The combination of our most recently completed annual results and our projected revenues, expenses and cash flows more than offset the impact of increasing fuel prices and other airline input costs. The stabilizing operating environment for U.S. airlines has resulted in annual yields increasing along with load factors, leading to improved financial results.

Goodwill. Our goodwill balance was $9.8 billion at December 31, 2012. We determined that there was no indication that Goodwill was impaired based upon our qualitative assessment of all relevant factors, including applicable factors noted in "Key Assumptions" above.

Identifiable Intangible Assets. Our identifiable intangible assets had a net carrying amount of $4.7 billion at December 31, 2012. Indefinite-lived assets are not amortized and consist primarily of routes, slots, the Delta tradename and assets related to SkyTeam and collaborative arrangements.

In 2012, we determined that there was no indication that our indefinite-lived intangible assets were impaired based upon our assessments. These assessments included analyses and weighting of all relevant factors, including the significant inputs and key assumptions which impact the fair value of our indefinite-lived intangible assets.

Long-Lived Assets

Our flight equipment and other long-lived assets have a recorded value of $20.7 billion at December 31, 2012. This value is based on various factors, including the assets' estimated useful lives and salvage values. We record impairment losses on flight equipment and other long-lived assets used in operations when events and circumstances indicate the assets may be impaired and the estimated future cash flows generated by those assets are less than their carrying amounts. Factors which could cause impairment include, but are not limited to, (1) a decision to permanently remove flight equipment or other long-lived assets from operations, (2) significant changes in the estimated useful life, (3) significant changes in projected cash flows, (4) permanent and significant declines in fleet fair values and (5) changes to the regulatory environment. For long-lived assets held for sale, we discontinue depreciation and record impairment losses when the carrying amount of these assets is greater than the fair value less the cost to sell.

To determine whether impairments exist for aircraft used in operations, we group assets at the fleet-type level (the lowest level for which there are identifiable cash flows) and then estimate future cash flows based on projections of capacity, passenger mile yield, fuel costs, labor costs and other relevant factors. If an impairment occurs, the impairment loss recognized is the amount by which the aircraft's carrying amount exceeds its estimated fair value. We estimate aircraft fair values using published sources, appraisals and bids received from third parties, as available.

Income Tax Valuation Allowance

We periodically assess whether it is more likely than not that we will generate sufficient taxable income to realize our deferred income tax assets. We establish valuation allowances if it is not likely we will realize our deferred income tax assets. In making this determination, we consider all available positive and negative evidence and make certain assumptions. We consider, among other things, our future projections of sustained profitability, deferred tax liabilities, the overall business environment, our historical financial results, our industry's historically cyclical financial results and potential current and future tax planning strategies.

We recorded a full valuation allowance in 2004 due to our cumulative three year loss position at that time, compounded by the negative industry-wide business trends and outlook. At December 31, 2012, we had an $11.0 billion valuation allowance established against our deferred income tax assets, which represents a full valuation allowance against our net deferred income tax asset.

During the March 2012 quarter, we moved from a cumulative loss position over the previous three years to a cumulative income position for the first time since we established a full valuation allowance. We have concluded as of December 31, 2012 that the valuation allowance was still needed on our net deferred tax assets based upon the weight of the factors described above, especially considering the history of losses. We continue to evaluate our cumulative income position and income trend as well as our future projections of sustained profitability and whether this profitability trend constitutes sufficient positive evidence to support a reversal of our valuation allowance (in full or in part).

Defined Benefit Pension Plans

We sponsor defined benefit pension plans for eligible employees and retirees. These plans are closed to new entrants and frozen for future benefit accruals. As of December 31, 2012, the unfunded benefit obligation for these plans recorded on our Consolidated Balance Sheet was $13.3 billion. During 2012, we contributed $697 million to these plans and recorded $368 million of expense in salaries and related costs on our Consolidated Statement of Operations. In 2013, we estimate we will contribute approximately $675 million to these plans and that our expense will be approximately $350 million. The most critical assumptions impacting our defined benefit pension plan obligations and expenses are the discount rate and the expected long-term rate of return on the plan assets.

Weighted Average Discount Rate. We determine our weighted average discount rate on our measurement date primarily by reference to annualized rates earned on high quality fixed income investments and yield-to-maturity analysis specific to our estimated future benefit payments. We used a weighted average discount rate to value the obligations of 4.11% and 4.94% at December 31, 2012 and 2011, respectively. Our weighted average discount rate for net periodic pension benefit cost in each of the past three years has varied from the rate selected on our measurement date, ranging from 4.95% to 5.93% between 2010 and 2012.

Expected Long-Term Rate of Return. Our expected long-term rate of return on plan assets of 9% is based primarily on plan-specific investment studies using historical market return and volatility data. Modest excess return expectations versus some public market indices are incorporated into the return projections based on the actively managed structure of the investment programs and their records of achieving such returns historically. We also expect to receive a premium for investing in less liquid private markets. We review our rate of return on plan asset assumptions annually. Our annual investment performance for one particular year does not, by itself, significantly influence our evaluation. Our actual historical annualized 20-year rate of return on plan assets for our defined benefit pension plans exceeded 9% as of December 31, 2012. The investment strategy for our defined benefit pension plan assets is to use a diversified mix of global public and private equity portfolios, public and private fixed income portfolios and private real estate and natural resource investments to earn a long-term investment return that meets or exceeds our annualized return target. Our expected long-term rate of return on assets for net periodic pension benefit cost for the year ended December 31, 2012 was 9%.

The impact of a 0.50% change in these assumptions is shown in the table below:



Change in Assumption	Effect on 2013 Pension Expense	Effect on Accrued Pension Liability at December 31, 2012
0.50% decrease in weighted average discount rate	-$5 million	+$1.4 billion
0.50% increase in weighted average discount rate	—	- $1.3 billion
0.50% decrease in expected long-term rate of return on assets	+$40 million	—
0.50% increase in expected long-term rate of return on assets	- $40 million	—

Funding. Our funding obligations for qualified defined benefit plans are governed by the Employee Retirement Income Security Act. The Pension Protection Act of 2006 allows commercial airlines to elect alternative funding rules (“Alternative Funding Rules”) for defined benefit plans that are frozen. Delta elected the Alternative Funding Rules under which the unfunded liability for a frozen defined benefit plan may be amortized over a fixed 17-year period and is calculated using an 8.85% interest rate.

While the Pension Protection Act makes our funding obligations for these plans more predictable, factors outside our control continue to have an impact on the funding requirements. Estimates of future funding requirements are based on various assumptions and can vary materially from actual funding requirements. Assumptions include, among other things, the actual and projected market performance of assets; statutory requirements; and demographic data for participants. For additional information, see Note 11 of the Notes to the Consolidated Financial Statements.

Recent Accounting Standards

Presentation of Comprehensive Income

In June 2011, the FASB issued "Presentation of Comprehensive Income." The standard revises the presentation and prominence of the items reported in other comprehensive income and is effective retrospectively for fiscal years beginning after December 15, 2011. We adopted this standard in 2012 and have presented comprehensive income in our Consolidated Statements of Comprehensive Income (Loss).

Supplemental Information

We sometimes use information that is derived from the Consolidated Financial Statements, but that is not presented in accordance with accounting principles generally accepted in the U.S. (“GAAP”). Certain of this information are considered to be “non-GAAP financial measures” under the U.S. Securities and Exchange Commission rules. The non-GAAP financial measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for or superior to GAAP results.

The following tables show reconciliations of non-GAAP financial measures to the most directly comparable GAAP financial measures.

We exclude the following items from CASM to determine CASM-Ex:


•	Aircraft fuel and related taxes. The volatility in fuel prices impacts the comparability of year-over-year financial performance. Management believes the exclusion of aircraft fuel and related taxes (including our contract carriers under capacity purchase arrangements) allows investors to better understand and analyze our non-fuel costs and our year-over-year financial performance.


•	Ancillary businesses. Ancillary businesses are not related to the generation of a seat mile. These businesses include aircraft maintenance and staffing services we provide to third parties and our vacation wholesale operations.


•	Profit sharing. Management believes the exclusion of this item provides a more meaningful comparison of our results to the airline industry and prior years' results.


•	Restructuring and other items. Management believes the exclusion of this item is helpful to investors to evaluate our recurring core operational performance in the period shown.


•	MTM adjustments. MTM adjustments are based on market prices as of the end of the reporting period for contracts settling in future periods. Such market prices are not necessarily indicative of the actual future value of the underlying hedge in the contract settlement period. Therefore, we adjust fuel expense for these items to arrive at a more meaningful measure of fuel cost.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We have market risk exposure related to aircraft fuel prices, interest rates and foreign currency exchange rates. Market risk

is the potential negative impact of adverse changes in these prices or rates on our Consolidated Financial Statements. In an

effort to manage our exposure to these risks, we enter into derivative contracts and may adjust our derivative portfolio as

market conditions change. We expect adjustments to the fair value of financial instruments to result in ongoing volatility in

earnings and stockholders' equity.

The following sensitivity analysis does not consider the effects of a change in demand for air travel, the economy as a whole or actions we may take to seek to mitigate our exposure to a particular risk. For these and other reasons, the actual results of changes in these prices or rates may differ materially from the following hypothetical results.

Aircraft Fuel Price Risk

Our results of operations are materially impacted by changes in aircraft fuel prices. We actively manage our fuel price risk through a hedging program intended to reduce the financial impact on us from changes in the price of jet fuel. This fuel hedging program utilizes several different contract and commodity types. The economic effectiveness of this hedge portfolio is frequently tested against our financial targets. The hedge portfolio is rebalanced from time to time according to market conditions, which may result in locking in gains or losses on hedge contracts prior to their settlement dates.

Our fuel hedge portfolio consists of call options; put options; combinations of two or more call options and put options; swap contracts; and futures contracts. The products underlying the hedge contracts include heating oil, crude oil, jet fuel and diesel fuel, as these commodities are highly correlated with the price of jet fuel that we consume. Our fuel hedge contracts contain margin funding requirements. The margin funding requirements may cause us to post margin to counterparties or may cause counterparties to post margin to us as market prices in the underlying hedged items change. If fuel prices change significantly from the levels existing at the time we enter into fuel hedge contracts, we may be required to post a significant amount of margin. We may adjust our hedge portfolio from time to time in response to margin posting requirements.

For the year ended December 31, 2012, aircraft fuel and related taxes, including our contract carriers under capacity purchase agreements, accounted for $12.3 billion, or 36%, of our total operating expense. We recognized $66 million of net fuel hedge losses during the year ended December 31, 2012.

The following table shows the projected cash impact to fuel cost assuming 10% and 20% increases or decreases in fuel prices. The hedge gain (loss) reflects the change in the projected cash settlement value of our open fuel hedge contracts at December 31, 2012 based on their contract settlement dates, assuming the same 10% and 20% changes.

⁽¹⁾	Projections based upon the (increase) decrease to unhedged fuel cost as compared to the jet fuel price per gallon of $3.01, excluding transportation costs and taxes, at December 31, 2012 and estimated fuel consumption of 3.8 billion gallons for the year ending December 31, 2013.


⁽²⁾	Projections based on average futures prices by contract settlement month compared to futures prices at December 31, 2012.

Interest Rate Risk

Our exposure to market risk from adverse changes in interest rates is primarily associated with our long-term debt obligations. Market risk associated with our fixed and variable rate long-term debt relates to the potential reduction in fair value and negative impact to future earnings, respectively, from an increase in interest rates.

At December 31, 2012, we had $5.9 billion of fixed-rate long-term debt and $6.7 billion of variable-rate long-term debt. An increase of 100 basis points in average annual interest rates would have decreased the estimated fair value of our fixed-rate long-term debt by $260 million at December 31, 2012 and would have increased the annual interest expense on our variable-rate long-term debt by $40 million, exclusive of the impact of our interest rate hedge contracts.

Foreign Currency Exchange Risk

We are subject to foreign currency exchange rate risk because we have revenue and expense denominated in foreign currencies with our primary exposures being the Japanese yen and Canadian dollar. To manage exchange rate risk, we execute both our international revenue and expense transactions in the same foreign currency to the extent practicable. From time to time, we may also enter into foreign currency option and forward contracts. At December 31, 2012, we had open foreign currency forward contracts totaling a $123 million asset position. We estimate that a 10% increase or decrease in the price of the Japanese yen and Canadian dollar in relation to the U.S. dollar would change the projected cash settlement value of our open hedge contracts by a $90 million gain or $110 million loss, respectively, for the year ending December 31, 2013.
