                    SHARES OF EXPEDIA COMMON STOCK ISSUABLE
                     UPON EXERCISE OF THE EXPEDIA WARRANTS

    This prospectus relates to the resale of up to       warrants (the "Expedia
Warrants") to acquire a like number of shares of our common stock, par value
$.01, which are held by the holders named under the heading "Selling Security
Holders" in this prospectus.       of the Expedia Warrants are employee warrants
("Expedia Employee Warrants") whose initial issuance we registered pursuant to a
registration statement on Form S-3 that we filed with the Securities and
Exchange Commission on November 13, 2001, as amended from time to time, and up
to           of the Expedia Warrants are shareholder warrants ("Expedia
Shareholder Warrants") whose initial issuance we registered pursuant to a
registration statement on Form S-4 that we filed with the Securities and
Exchange Commission on August 22, 2001, as amended from time to time. The
Expedia Warrants were issued in connection with our recapitalization and the
merger of a wholly-owned subsidiary of USA Networks, Inc. ("USA") with and into
us, which we completed in             , 2002. We refer to the recapitalization
and merger together as the "merger" throughout this prospectus. See
"Summary--The Merger."

    This prospectus also relates to the resale by the selling security holders
of up to       shares of our common stock that are initially issuable upon
exercise of the Expedia Warrants. The Expedia Warrants and the shares of our
common stock issued upon the exercise of the Expedia Warrants offered by this
prospectus are referred to as the "Securities" throughout this prospectus.

    Each Expedia Warrant entitles its holder to purchase one share of Expedia
common stock at any time prior to             , 2009 upon payment of the
exercise price of $52.00 per share, subject to adjustment.

    We will not receive any proceeds from the sale of the Securities by the
selling security holders.

    After registration, the Securities may be sold from time to time to
purchasers directly by the selling security holders. Alternatively, the selling
security holders may offer the Securities through underwriters, dealers or
agents on terms to be determined at the time of the sale. See "Plan of
Distribution" on page 16.

    The selling security holders and any agents, dealers or underwriters that
participate with the selling security holders in the distribution of the
Securities may be deemed "underwriters" within the meaning of the Securities Act
of 1933, as amended (the "Securities Act"), and any commissions received by them
and any profit on the resale of the Securities purchased by them may be deemed
to be underwriting commissions or discounts under the Securities Act.

    Our common stock is quoted on the Nasdaq National Market under the symbol
"EXPE". On           , 2002, the most recent practicable date prior to the
filing of this prospectus, our common stock closed at $           per share. The

THE MERGER

    On             , 2002, USA completed its acquisition of a controlling
interest in Expedia through a merger of one of its subsidiaries with and into
Expedia. As a result of the merger, USA owns approximately   % our currently
outstanding shares and   % of the voting interest in Expedia. As a result of the
merger, we also own various travel and media-related assets previously owned by
USA.

    Approximately 10 days prior to the merger we distributed approximately
      Expedia Employee Warrants to certain holders of vested and unvested stock
options to acquire our common stock. In addition, immediately prior to the
merger, we recapitalized our common stock to create a new class of common stock,
Expedia Class B common stock, par value $.01 per share, which is entitled to 15
votes per share, provided that no Expedia shareholder or group of shareholders
can generally hold more than 94.9% of our total outstanding voting power. All of
the shares of Expedia Class B common stock are currently held by USA.

    For more detail on the merger, please refer to the Form S-4 registration
statement. For more detail on the distribution of Expedia Employee Warrants to
certain of our optionholders, please refer to the Form S-3 registration
statement.

ACQUISITION OF CLASSIC CUSTOM VACATIONS

    On January 23, 2002, we announced that we had entered into an agreement to
acquire certain of the assets, and assume certain of the liabilities, of Classic
Custom Vacations, a California corporation and a wholly owned subsidiary of
Classic Vacation Group, Inc., a New York corporation. In connection with the
transaction, we agreed to first purchase all of the outstanding debt of Classic
Vacation Group in exchange for approximately $47 million in shares of our common
stock. If the aggregate net proceeds to the Classic debt holders from the sale
of our shares is less than $47 million, we will fund the difference in value by
issuing additional shares or paying the remainder in cash or both. If the
aggregate net proceeds exceed $47 million, the excess will be returned to us. We
will then acquire the assets of Classic Custom Vacations for an aggregate
purchase price of approximately $52 million (consisting of approximately
$5 million in cash plus the cancellation of the $47 million of debt of Classic
Vacation Group we purchased) plus the assumption of certain liabilities. The
transaction is subject to customary closing conditions, including regulatory
approval and the approval of the stockholders of Classic Vacation Group. For
more detail on the Classic transaction, please refer to our Form 8-K, which we
filed on January 23, 2002.

                                  RISK FACTORS

    AN INVESTMENT IN THE SECURITIES INVOLVES A HIGH DEGREE OF RISK. YOU SHOULD
CONSIDER THE FOLLOWING FACTORS CAREFULLY BEFORE DECIDING TO PURCHASE THE
SECURITIES. ADDITIONAL RISKS NOT PRESENTLY KNOWN TO US OR THAT WE CURRENTLY DEEM
IMMATERIAL MAY ALSO IMPAIR OUR BUSINESS OPERATIONS.

RISK FACTORS RELATING TO USA'S ACQUISITION OF CONTROL OF EXPEDIA

    USA EXERCISES SIGNIFICANT CONTROL OVER EXPEDIA

    As a result of the merger, USA owns approximately   % of our outstanding
common equity and approximately   % of our total voting power. As a result, USA
generally has the ability to control the outcome of any matter submitted for the
vote or consent of our shareholders, except where a separate vote of the holders
of our common stock is required by Washington law. In addition, USA also
controls our board of directors. Subject to applicable Washington law and
agreements entered into as part of the merger transactions, USA generally is not
restricted with regard to its ability to control the election of our directors,
to cause the amendment of our articles of incorporation or bylaws, or generally
to exercise a controlling influence over our business and affairs. As a result
of USA's controlling interest in us, USA has the power to prevent, delay or
cause a change in control of Expedia and could take other actions that might be
favorable to USA but not necessarily favorable to our other shareholders.

    In addition, because our board of directors has approved the merger
transactions, our shareholders may not benefit from certain protections afforded
by the Washington anti-takeover statute in respect of future agreements with USA
or its affiliates.

    CONFLICTS OF INTEREST MAY ARISE BETWEEN USA AND EXPEDIA, WHICH MAY NOT BE
     RESOLVED IN A MANNER THAT DOES NOT ADVERSELY AFFECT OUR BUSINESS, FINANCIAL
     CONDITION OR RESULTS OF OPERATIONS

    Conflicts of interest may arise between us, on the one hand, and USA and its
other affiliates, on the other hand, in areas relating to past, ongoing and
future relationships, including corporate opportunities, potential acquisitions
or financing transactions, sales or other dispositions by USA of its interest in
Expedia and the exercise by USA of its ability to control our management and
affairs. Conflicts, disagreements or other disputes between us and USA may arise
and may not be resolved in a manner that does not adversely affect our business,
financial condition or results of operations.

    For instance, USA is engaged in a diverse range of media and
entertainment-related businesses, including businesses that may compete in one
or more businesses with us, including Hotel Reservations Network. In addition,
USA or its affiliates may acquire additional businesses that may conflict or
compete with us. Subject to applicable Washington law, USA is under no
obligation, and has not indicated any intention, to share any future business
opportunities available to it with us. Our amended and restated articles of
incorporation also include provisions that provide that (1) neither USA nor any
of its affiliates has any duty to refrain from engaging in the same or similar
activities or lines of business of Expedia, thereby competing with us, and
(2) neither USA nor any of its affiliates has any duty to communicate or offer
corporate opportunities to us and none of them will be liable for breach of any
fiduciary duty to us, as a shareholder of Expedia or otherwise, in connection
with such opportunities, provided that the procedures provided for in our
articles of incorporation are followed.

    OUR DIRECTORS AND OFFICERS MAY HAVE INTERESTS IN USA AND ITS SUBSIDIARIES
     WHICH COULD CREATE POTENTIAL CONFLICTS OF INTEREST

    Ownership interests of directors or officers of Expedia in USA common stock,
or ownership of directors or officers of USA in Expedia common stock or service
as both a director or officer of Expedia and a director, officer or employee of
USA, could create or appear to create potential conflicts of interest when
directors and officers are faced with decisions that could have different

                                       6

implications for us and USA. Barry Diller is Chairman of our board of directors.
A number of other members of our board of directors are also directors, officers
or employees of USA. In addition, interlocking relationships may exist between
certain members of our board of directors and members of the boards of directors
of other USA subsidiaries with which we directly compete, including Hotel
Reservations Network, Inc., and important suppliers of ours that also have
strong business relationships with our direct competitors.

    USA/EXPEDIA MAY NOT REALIZE ALL OF THE ANTICIPATED BENEFITS OF THE MERGER
     TRANSACTIONS

    The success of the merger transactions will depend, in part, on the ability
of USA and us to realize certain anticipated growth opportunities from
integrating our businesses with the businesses of USA and its affiliates. We
cannot assure you that this integration will result in the realization of the
full anticipated benefits of the growth opportunities or that these benefits
will be achieved within the anticipated time frame or at all. In addition, legal
arrangements between USA or its affiliates and certain third parties may
restrict the ability of the parties to integrate parts of their businesses with
the businesses of USA or its affiliates.

    MICROSOFT IS ABLE TO COMPETE WITH US

    In connection with the merger, we and Microsoft terminated the shareholder
agreement between Microsoft and us, which agreement included, among other
things, an agreement by Microsoft not to compete with us. As a result, Microsoft
is currently able to compete with us, which could have a negative impact on our
business.

RISK FACTORS RELATING TO USA

    USA DEPENDS ON ITS KEY PERSONNEL

    USA is dependent upon the continued contributions of its senior corporate
management, particularly Mr. Diller, and certain key employees for its future
success. Mr. Diller is the Chairman of the Board and Chief Executive Officer of
USA. Mr. Diller does not have an employment agreement with USA, although he has
been granted options to purchase a substantial number of shares of USA common
stock.

    If Mr. Diller no longer serves in his positions at USA, the business of USA,
as well as the market price of USA common stock, could be substantially
adversely affected. In addition, under the terms of a governance agreement,
dated as of October 19, 1997, among Universal Studios, Inc., HSN, Inc. (now
USA), Mr. Diller and Liberty Media Corporation, if Mr. Diller no longer serves
as Chief Executive Officer of USA, then certain restrictions on Universal
Studios' conduct will be eliminated, and the ability of Universal Studios (which
is controlled by Vivendi Universal S.A.) to increase its equity interest in USA
will be accelerated. We cannot assure you that USA will be able to retain the
services of Mr. Diller or any other members of senior management or key
employees of USA.

    USA IS CONTROLLED BY MR. DILLER AND IN HIS ABSENCE, WILL BE CONTROLLED BY
     VIVENDI UNIVERSAL AND/OR LIBERTY MEDIA

    Mr. Diller, through entities he controls, currently beneficially owns or has
the right to vote 100% of the shares of Class B common stock, par value $.01 per
share, of USA, which is sufficient to control the outcome of any matter
submitted to a vote or for the consent of USA shareholders with respect to which
holders of USA common stock and USA Class B common stock vote together as a
single class. Mr. Diller, subject to the terms of a stockholders agreement,
dated as of October 19, 1997 (the "Current Stockholders Agreement"), among
Universal Studios, Liberty Media, Mr. Diller, USA and The Seagram Company Ltd.
(now controlled by Vivendi Universal S.A.), effectively controls the outcome of
all matters submitted to a vote or for the consent of USA stockholders (other
than with

                                       7

respect to the election by the holders of USA common stock of 25% of the members
of the board of directors of USA (rounded up to the nearest whole number) and
certain matters as to which a separate class vote of the holders of USA common
stock is required under Delaware law).

    Under the Current Stockholders Agreement, Mr. Diller, Universal Studios and
Liberty Media have agreed that USA securities owned by any of Mr. Diller,
Universal Studios, Liberty Media and certain of their affiliates will not be
voted in favor of the taking of any action with respect to certain fundamental
changes relating to USA, except with the consent of each of Mr. Diller,
Universal Studios and Liberty Media. Accordingly, in respect of these matters,
each of Mr. Diller, Universal Studios and Liberty Media currently has the
ability to veto, in his or its sole discretion, the taking of any action with
respect to these matters. Following completion of the USA's pending transaction
with Vivendi Universal, each of Mr. Diller and Liberty Media will have the right
to consent to the fundamental changes in the event that USA is highly leveraged.
In addition, we cannot assure you that Mr. Diller and Liberty Media, and prior
to completion of the USA/Vivendi Universal transaction, Universal Studios, will
agree in the future on any such transaction or action, in which case USA would
not be able to engage in such transaction or take such action.

    In addition, any third party seeking to acquire USA would be required to
negotiate such transaction with Mr. Diller, Vivendi Universal and Liberty Media,
and the interests of any one or more of such persons as shareholders may be
different from the interests of other USA shareholders.

    Upon Mr. Diller's permanent departure from USA, USA may change in various
fundamental respects. For example, prior to the completion of the Vivendi
Universal transaction, generally, Vivendi Universal, through Universal Studios,
would be able to control USANi LLC, through which a significant portion of USA's
businesses are currently owned, and also would have the ability to seek to
directly control USA. In addition, Universal Studios and Liberty Media have
certain agreements relating to the management and governance of USA, as well as
the voting and disposition of their shares of USA stock. Following completion of
the USA/Vivendi Universal transaction, generally, Liberty Media would be able to
control USA through its ownership of its USA Class B shares.

RISK FACTORS RELATING TO EXPEDIA

    DECLINES OR DISRUPTIONS IN THE TRAVEL INDUSTRY, SUCH AS THOSE CAUSED BY
     TERRORISM OR GENERAL ECONOMIC DOWNTURNS, COULD REDUCE EXPEDIA'S REVENUES

    Expedia relies on the health and growth of the travel industry. Travel is
highly sensitive to traveler safety concerns, and thus declines after acts of
terrorism that affect the safety of travelers. The terrorist attacks of
September 11, 2001 on the World Trade Center in New York City and the Pentagon
in northern Virginia using hijacked commercial airliners resulted in the
cancellation of a significant number of Expedia's existing travel bookings and a
decrease in new travel bookings through Expedia, all of which will reduce
Expedia's revenues for at least the quarters ended September 30, 2001 and
December 31, 2001. The long-term effects of these events could include, among
other things, a protracted decrease in demand for air travel due to fears
regarding additional acts of terrorism, military responses to acts of terrorism
and increased costs and reduced operations by airlines due, in part, to new
security directives adopted by the Federal Aviation Administration. These
effects, depending on their scope and duration--which Expedia cannot predict at
this time--could significantly impact Expedia's long-term results of operations
or financial condition.

    In addition, travel is sensitive to business and personal discretionary
spending levels and tends to decline during general economic downturns, which
could also reduce Expedia's revenues. Other adverse trends or events that tend
to reduce travel and may reduce Expedia's revenues include:

    - political instability;

    - regional hostilities;

                                       8

    - price escalation in the airline industry or other travel-related
      industries;

    - increased occurrence of travel-related accidents;

    - airline or other travel-related strikes; and

    - bad weather.

    OUR OPERATING RESULTS ARE VOLATILE AND DIFFICULT TO PREDICT

    Our annual and quarterly operating results have fluctuated in the past and
may fluctuate significantly in the future due to a variety of factors, many of
which are outside of our control. Because our operating results are volatile and
difficult to predict, we believe that quarter-to-quarter comparisons of our
operating results are not a good indication of our future performance. It is
likely that in some future quarter our operating results will fall below the
expectations of securities analysts or investors. In this event, the trading
price of our common stock may decline significantly.

    Factors that may cause us to fail to meet the expectations of securities
analysts or investors include the following:

    - our inability to obtain travel products on satisfactory terms from our
      travel suppliers;

    - the ability of our competitors to offer new or enhanced websites, services
      or products or similar services or products with lower prices;

    - our inability to obtain new customers at reasonable cost, retain existing
      customers or encourage repeat purchases;

    - decreases in the number of visitors to our websites or our inability to
      convert visitors to our websites into customers;

    - our inability to adequately maintain, upgrade and develop our websites,
      the systems that we use to process customers' orders and payments or our
      computer network;

    - our inability to retain existing airlines, hotels, rental car companies
      and other suppliers of travel services or to obtain new travel suppliers;

    - fluctuating gross margins due to a changing mix of revenues;

    - the termination of existing relationships with key service providers or
      failure to develop new ones;

    - the amount and timing of operating costs relating to expansion of our
      operations; and

    - economic conditions specific to the Internet, online commerce and the
      travel industry.

    WE DEPEND ON OUR RELATIONSHIPS WITH TRAVEL SUPPLIERS AND COMPUTER
     RESERVATION SYSTEMS AND ADVERSE CHANGES IN THESE RELATIONSHIPS COULD AFFECT
     OUR INVENTORY OF TRAVEL OFFERINGS

    Our business relies on relationships with travel suppliers, and it would be
negatively affected by adverse changes in these relationships. We depend on
travel suppliers to enable us to offer our customers comprehensive access to
travel services and products. Consistent with industry practices, we currently
have few agreements with our travel suppliers obligating them to sell services
or products through our websites. It is possible that travel suppliers may
choose not to make their inventory of services and products available through
online distribution. Travel suppliers could elect to sell exclusively through
other sales and distribution channels or to restrict our access to their
inventory, either of which could significantly decrease the amount or breadth of
our inventory of available travel offerings. Of particular note is Orbitz, the
airline direct-distribution website, which was launched in June 2001 and is
owned by American Airlines, Continental Airlines, Delta Air Lines, Northwest
Airlines and United Air Lines. Forester Research reports that Orbitz is the only
website for consumers

                                       9

to find unpublished special fares on these and at least 23 other airlines.
Additionally, American Airlines, United Air Lines, Northwest Airlines,
Continental Air Lines, US Airways Group and America West Airlines entered into a
joint venture to launch a separate site known as "Hotwire", which offers
unpublished special fares on certain carriers. If a substantial number of our
airline suppliers collectively agree or choose to restrict their special fares
solely to Orbitz or Hotwire, such action may have a material adverse affect on
our business. We also depend on travel suppliers for advertising revenues.
Adverse changes in any of these relationships, whether due to Orbitz, Hotwire or
otherwise, could reduce the amount of inventory that we are able to offer
through our websites.

    A DECLINE IN COMMISSION RATES AND FEES OR THE ELIMINATION OF COMMISSIONS
     COULD REDUCE OUR REVENUES AND MARGINS

    A substantial majority of our online revenues depends on the commissions and
fees paid by travel suppliers for bookings made through our online travel
service. Generally, we do not have written commission agreements with our
suppliers. As is standard practice in the travel industry, we rely on informal
arrangements for the payment of commissions. Travel suppliers are not obligated
to pay any specified commission rate for bookings made through our websites. We
cannot assure you that airlines, hotel chains or other travel suppliers will not
reduce current industry commission rates or eliminate commissions entirely,
either of which could reduce our revenues and margins.

    WE EXPECT OUR ACCOUNTING LOSSES TO CONTINUE

    To date, we have incurred substantial net losses due mainly to stock-based
compensation and acquisitions made by us since our initial public offering. For
the fiscal year ended June 30, 2001, we had a net loss of $78.1 million. If our
revenues do not grow as expected, or if increases in our expenses are not in
line with our plans, there could be a material adverse effect on our business,
operating results and financial condition.

    WE COMPETE WITH A VARIETY OF COMPANIES WITH RESPECT TO EACH PRODUCT OR
     SERVICE WE OFFER

    These competitors include:

    - internet travel agents such as Travelocity.com, Orbitz.com and American
      Express Interactive, Inc.;

    - local, regional, national and international traditional travel agencies;

    - consolidators and wholesalers of airline tickets, hotels and other travel
      products, including Hotwire.com, Cheaptickets.com and Priceline.com;

    - airlines, hotels, rental car companies, cruise operators and other travel
      service providers, whether working individually or collectively, some of
      which are suppliers to our websites; and

    - operators of travel industry reservation databases.

    In addition to the traditional travel agency channel, many travel suppliers
also offer their travel services as well as third-party travel services directly
through their own websites. These travel suppliers include many suppliers with
which we do business. Suppliers also sell their own services directly to
consumers, predominantly by telephone. As the market for online travel services
grows, we believe that travel suppliers, traditional travel agencies, travel
industry information providers and other companies will increase their efforts
to develop services that compete with our services by selling inventory from a
wide variety of suppliers. We cannot assure you that our online operations will
compete successfully with any current or future competitors.

    Many of our competitors have longer operating histories, larger customer
bases, greater brand recognition and significantly greater financial, marketing
and other resources than we have and may enter into strategic or commercial
relationships with larger, more established and better-financed

                                       10

companies. Some of our competitors may be able to secure services and products
from travel suppliers on more favorable terms, devote greater resources to
marketing and promotional campaigns and commit more resources to website and
systems development than we are able to devote. In addition, the introduction of
new technologies and the expansion of existing technologies may increase
competitive pressures. Increased competition may result in reduced operating
margins, as well as loss of market share and brand recognition. We cannot assure
you that we will be able to compete successfully against current and future
competitors. Competitive pressures faced by us could have a material adverse
effect on our business, operating results and financial condition.

    IF WE FAIL TO INCREASE OUR BRAND RECOGNITION AMONG CONSUMERS, WE MAY NOT BE
     ABLE TO ATTRACT AND EXPAND OUR ONLINE TRAFFIC

    We believe that maintaining and enhancing the Expedia-Registered Trademark-
brand is a critical aspect of our efforts to attract and expand our online
traffic. The number of Internet sites that offer competing services increases
the importance of maintaining and enhancing brand recognition. Promotion of the
Expedia-Registered Trademark- brand will depend largely on our success in
providing a high-quality online experience supported by a high level of customer
service. In addition, we intend to spend substantial amounts on marketing and
advertising with the intention of continuing to expand our brand recognition to
attract and retain online users and to respond to competitive pressures.
However, we cannot assure you that these expenditures will be effective to
promote our brand or that our marketing efforts generally will achieve our
goals.

    INTERRUPTIONS IN SERVICE FROM THIRD PARTIES COULD IMPAIR THE QUALITY OF OUR
     SERVICE

    We rely on third-party computer systems and third-party service providers,
including the computerized central reservation systems of the airline, hotel and
car rental industries to make airline ticket, hotel room and car rental
reservations and credit card verifications and confirmations.

    Currently, a majority of our transactions are processed through Worldspan,
L.P. and Pegasus Solutions, Inc. We rely on TRX, Inc. and PeopleSupport, Inc. to
provide a significant portion of our telephone and email customer support, as
well as to print and deliver airline tickets as necessary. Microsoft also
services a significant amount of our information systems as part of an amended
and restated services agreement, which Microsoft has agreed to extend through
September 2002. Any interruption in these third-party services or a
deterioration in their performance could impair the quality of our service. If
our arrangement with any of these third parties is terminated, we may not find
an alternate source of systems support on a timely basis or on commercially
reasonable terms. In particular, any migration from the Worldspan system could
require a substantial commitment of time and resources and hurt our business.

    OUR SUCCESS DEPENDS ON MAINTAINING THE INTEGRITY OF OUR SYSTEMS AND
     INFRASTRUCTURE

    In order to be successful, we must continue to provide reliable, real-time
access to our systems for our customers and suppliers. As our operations
continue to grow in both size and scope, domestically and internationally, we
will need to improve and upgrade our systems and infrastructure to offer an
increasing number of customers and travel suppliers enhanced products, services,
features and functionality. The expansion of our systems and infrastructure will
require us to commit substantial financial, operational and technical resources
before the volume of business increases, with no assurance that the volume of
business will increase. Consumers and suppliers will not tolerate a service
hampered by slow delivery times, unreliable service levels or insufficient
capacity, any of which could have a material adverse effect on our business,
operating results and financial condition.

                                       11

    In this regard, our operations face the risk of systems failures. Our
systems and operations are vulnerable to damage or interruption from fire,
flood, power loss, telecommunications failure, break-ins, earthquake and similar
events. Our business interruption insurance may not adequately compensate us for
losses that may occur. The occurrence of a natural disaster or unanticipated
problems at our facilities in Washington or Travelscape's facilities in Nevada
could cause interruptions or delays in our business, loss of data or render us
unable to process reservations. In addition, the failure of our computer and
communications systems to provide the data communications capacity required by
us, as a result of human error, natural disaster or other operational
disruptions, could result in interruptions in our service. The occurrence of any
or all of these events could adversely affect our reputation, brand and
business.

    OUR BUSINESS IS EXPOSED TO RISKS ASSOCIATED WITH ONLINE COMMERCE SECURITY
     AND CREDIT CARD FRAUD

    Consumer concerns over the security of transactions conducted on the
Internet or the privacy of users may inhibit the growth of the Internet and
online commerce. To transmit confidential information such as customer credit
card numbers securely, we rely on encryption and authentication technology.
Unanticipated events or developments could result in a compromise or breach of
the systems we use to protect customer transaction data. Furthermore, our
servers may also be vulnerable to viruses transmitted via the Internet. While we
proactively checks for intrusions into our infrastructure, a new and undetected
virus could cause a service disruption.

    To date, our results have been impacted due to reservations placed with
fraudulent credit card data. We record these reserves because, under current
credit card practices and the rules of the Airline Reporting Corporation, we may
be held liable for fraudulent credit card transactions on our websites and other
payment disputes with customers. Since discovering this fraudulent activity, we
have put additional anti-fraud measures in place above and beyond our existing
credit card verification procedures; however, a failure to control fraudulent
credit card transactions adequately could further adversely affect our business.

    RAPID TECHNOLOGICAL CHANGES MAY RENDER OUR TECHNOLOGY OBSOLETE OR DECREASE
     THE COMPETITIVENESS OF OUR SERVICES

    To remain competitive in the online travel industry, we must continue to
enhance and improve the functionality and features of our websites. The Internet
and the online commerce industry are rapidly changing. In particular, the online
travel industry is characterized by increasingly complex systems and
infrastructures. If competitors introduce new services embodying new
technologies, or if new industry standards and practices emerge, our existing
websites and proprietary technology and systems may become obsolete. Our future
success will depend on our ability to do the following:

    - enhance our existing services;

    - develop and license new services and technologies that address the
      increasingly sophisticated and varied needs of our prospective customers
      and suppliers; and

    - respond to technological advances and emerging industry standards and
      practices on a cost-effective and timely basis.

    Developing our websites and other proprietary technology entails significant
technical and business risks. We may use new technologies ineffectively or we
may fail to adapt our websites, transaction-processing systems and network
infrastructure to customer requirements or emerging industry standards. If we
face material delays in introducing new services, products and enhancements, our
customers and suppliers may forego the use of our services and use those of our

    OUR INTERNATIONAL OPERATIONS INVOLVE RISKS RELATING TO TRAVEL PATTERNS AND
     PRACTICES AND INTERNET-BASED COMMERCE

    We operate in the United Kingdom, Germany, Canada, Belgium and France and
have websites in Italy and the Netherlands. In order to achieve widespread
acceptance in each country we enter, we believe that we must tailor our services
to the unique customs and cultures of that country. Learning the customs and
cultures of various countries, particularly with respect to travel patterns and
practices, is a difficult task and our failure to do so could slow our growth in
those countries.

    In addition, we face additional risks in operating internationally, such as:

    - delays in the development of the Internet as a broadcast, advertising and
      commerce medium in international markets;

    - difficulties in managing operations due to distance, language and cultural
      differences, including issues associated with establishing management
      systems infrastructures in individual foreign markets;

    - unexpected changes in regulatory requirements;

    - tariffs and trade barriers and limitations on fund transfers;

    - difficulties in staffing and managing foreign operations;

    - potential adverse tax consequences;

    - exchange rate fluctuations; and

    - increased risk of piracy and limits on our ability to enforce our
      intellectual property rights.

    Any of these factors could harm our business. We do not currently hedge our
foreign currency exposures.

    WE MAY BE FOUND TO HAVE INFRINGED ON INTELLECTUAL PROPERTY RIGHTS OF OTHERS
     WHICH COULD EXPOSE US TO SUBSTANTIAL DAMAGES AND RESTRICT OUR OPERATIONS

    We could face claims that we have infringed the patents, copyrights or other
intellectual property rights of others. In addition, we may be required to
indemnify travel suppliers for claims made against them. Any claims against us
could require us to spend significant time and money in litigation, delay the
release of new products or services, pay damages, develop new intellectual
property or acquire licenses to intellectual property that is the subject of the
infringement claims. These licenses, if required, may not be available on
acceptable terms or at all. As a result, intellectual property claims against us
could have a material adverse effect on our business, operating results and
financial condition.

    BECAUSE OUR MARKET IS SEASONAL, OUR QUARTERLY RESULTS WILL FLUCTUATE

    Our business experiences seasonal fluctuations, reflecting seasonal trends
for the products and services offered by our websites. For example, demand for
travel bookings may increase in anticipation of summer vacations and holiday
periods, but online travel bookings may decline with reduced Internet usage
during the summer months. These factors could cause our revenues to fluctuate
from quarter to quarter. Our results may also be affected by seasonal
fluctuations in the inventory made available to our service by travel suppliers.

                                       13

    OUR SUCCESS DEPENDS IN LARGE PART ON THE CONTINUING EFFORTS OF A FEW
     INDIVIDUALS AND OUR ABILITY TO CONTINUE TO ATTRACT, RETAIN AND MOTIVATE
     HIGHLY SKILLED EMPLOYEES

    We depend substantially on the continued services and performance of our
senior management, particularly Richard N. Barton, our chief executive officer
and president. These individuals may not be able to fulfill their
responsibilities adequately and may not remain with us. The loss of the services
of any executive officers or other key employees could hurt our business.

    As of January 15, 2002, we employed a total of approximately 970 full-time
employees. In order to achieve our anticipated growth, we will need to hire
additional qualified employees. If we do not succeed in attracting new employees
and retaining and motivating our current personnel, our business will be
adversely affected.

    OUR WEBSITES RELY ON INTELLECTUAL PROPERTY, AND WE CANNOT BE SURE THAT THIS
     INTELLECTUAL PROPERTY IS PROTECTED FROM COPY OR USE BY OTHERS, INCLUDING
     POTENTIAL COMPETITORS

    We regard much of our content and technology as proprietary and try to
protect our proprietary technology by relying on trademarks, copyrights, trade
secret laws and confidentiality agreements with consultants. In connection with
our license agreements with third parties, we seek to control access to and
distribution of our technology, documentation and other proprietary information.
Even with all of these precautions, it is possible for someone else to copy or
otherwise obtain and use our proprietary technology without our authorization or
to develop similar technology independently. Effective trademark, copyright and
trade secret protection may not be available in every country in which our
services are made available through the Internet, and policing unauthorized use
of our proprietary information is difficult and expensive. We cannot be sure
that the steps we have taken will prevent misappropriation of our proprietary
information. This misappropriation could have a material adverse effect on our
business. In the future, we may need to go to court to enforce our intellectual
property rights, to protect our trade secrets or to determine the validity and
scope of the proprietary rights of others. This litigation might result in
substantial costs and diversion of resources and management attention.

    We currently license from third parties, including Microsoft, some of the
technologies incorporated into our websites. As we continue to introduce new
services that incorporate new technologies, we may be required to license
additional technology from Microsoft and others. We cannot be sure that these
third-party technology licenses will continue to be available on commercially
reasonable terms, if at all.

RISKS RELATED TO THE OFFERING

    AN ACTIVE TRADING MARKET FOR THE EXPEDIA WARRANTS MAY NOT DEVELOP

    The Expedia Warrants to be issued in the merger and to Expedia option
holders are a new type of security for which there is currently no public
market. If these securities are traded after their initial issuance, they may
trade at a discount from their initial valuations, depending on prevailing
interest rates, the market for similar securities, the price of Expedia common
stock, our performance and other factors. In addition, we do not know whether an
active trading market will develop for the Expedia Warrants.

    OUR COMMON STOCK PRICE MAY EXPERIENCE EXTREME PRICE AND VOLUME FLUCTUATIONS,
     AND INVESTORS IN OUR STOCK MAY NOT BE ABLE TO RESELL THEIR SHARES AT OR
     ABOVE THE PRICE THAT THEY PAID FOR THEM

    Due to fluctuations in the market price of our common stock, you may be
unable to resell your shares at or above the price that you paid for them. The
market price of our common stock has fluctuated in the past and is likely to be
highly volatile. In addition, the stock market in general and the market prices
of shares of Internet companies in particular, have been extremely volatile and
have

                                       14

experienced fluctuations that have often been unrelated or disproportionate to
the operating performance of such companies. The market price of our common
stock could continue to be highly volatile and is likely to experience wide
fluctuations in response to factors, many of which are largely beyond our
control, including the following:

    - actual or anticipated variations in our quarterly operating results;

    - announcements of technological innovations or new services by us or our
      competitors;

    - changes in financial estimates by securities analysts;

    - conditions or trends in the Internet or online commerce industries;

    - changes in the economic performance or market valuations of other
      Internet, online commerce or travel companies;

    - announcements by us or our competitors of significant acquisitions;

    - strategic partnerships, joint ventures or capital commitments;

    - additions or departures of key personnel;

    - release of lock-up or other transfer restrictions on our outstanding
      shares of common stock or sales of additional shares of common stock;

    - potential litigation; and

    - conditions which may affect the closing of the merger.

                                       15

                                USE OF PROCEEDS

    All of the Securities being offered under this prospectus from time to time
are being sold by the selling security holders. We will not receive any of the
proceeds from the sale of the Securities by the selling security holders.

                              PLAN OF DISTRIBUTION

    The selling security holders may transfer, pledge, donate or assign the
Securities to lenders or others and each of such persons will be deemed to be a
"selling security holder" for purposes of this prospectus. The number of
Securities beneficially owned by a selling security holder who transfers,
pledges, donates or assigns Securities will decrease as and when they take such
actions. The plan of distribution for Securities sold hereunder will otherwise
remain unchanged, except that the transferees, pledgees, donees or assignees
will be selling security holders hereunder.

METHOD OF SALE

    The Securities may be sold pursuant to this prospectus by the selling
security holders in any of the following ways:

    - The Securities may be sold through underwriters in one or more
      underwritten offerings on a firm commitment or best efforts basis. The
      Securities may be sold through a broker or brokers, acting as principals
      or agents. Transactions through broker-dealers may include block trades in
      which brokers or dealers will attempt to sell the Securities as agent but
      may position and resell the block as principal to facilitate the
      transaction. The Securities may be sold through dealers or agents or to
      dealers acting as market makers. Broker-dealers may receive compensation
      in the form of discounts, concessions, or commissions from the selling
      security holders and/or the purchasers of the Securities for whom such
      broker-dealers may act as agents or to whom they sell as principal, or
      both (which compensation as to a particular broker-dealer might be in
      excess of customary commissions).

    - The Securities may be sold on any exchange on which the Securities are
      listed.

    - The Securities may be sold in private sales directly to purchasers.

    A selling security holder may enter into hedging transactions with
counterparties (including broker-dealers), and the counterparties may engage in
short sales of the Securities in the course of hedging the positions they assume
with such selling security holder, including, without limitation, in connection
with distribution of the Securities by such counterparties. In addition, the
selling security holders may sell short the Securities, and in such instances,
this prospectus may be delivered in connection with such short sales and the
Securities offered hereby may be used to cover such short sales. The selling
security holders may also enter into option or other transactions with
counterparties that involve the delivery of the Securities to the
counterparties, who may then resell or otherwise transfer such Securities.

    The selling security holders may also loan or pledge the Securities and the
borrower or pledgee may sell the Securities as loaned or upon a default may sell
or otherwise transfer the pledged Securities.

    Securities covered by this prospectus which qualify for sale pursuant to
Rule 144 or Rule 145 of the Securities Act may be sold under Rule 144 or
Rule 145 rather than pursuant to this prospectus.

    Each of the selling security holders reserves the right to accept and,
together with their agents from time to time to reject, in whole or in part, any
proposed purchase of Securities to be made directly or through agents.

                                       16

TIMING AND PRICE

    The Securities may be sold from time to time by a selling security holder.
There is no assurance that any selling security holder will sell or dispose of
any of its Securities.

    We are required to keep this registration statement effective until the
earlier of the date on which any selling security holder no longer holds the
Securities or the one-year anniversary of the closing date of the merger.

    Selling security holders will be subject to applicable provisions of the
Exchange Act and the rules and regulations thereunder, which provisions may
limit the timing of purchases and sales of our securities by them.

    Securities may be sold at a fixed price, which may be changed, or at varying
prices determined at the time of sale or at negotiated prices. Such prices will
be determined by the holders of such securities or by agreement between such
holders and purchasers or underwriters and/or dealers (who may receive fees or
commissions in connection therewith).

PROCEEDS, COMMISSIONS AND EXPENSES

    The aggregate proceeds to the selling security holders from the sale of the
Securities offered by them hereby will be the purchase price of such Securities
less discounts, concessions and commissions, if any. We will not receive any of
the proceeds from this offering.

    Each selling security holder will be responsible for payment of commissions,
concessions and discounts of underwriters, dealers or agents.

    In connection with the Securities to be sold by Microsoft Corporation or its
affiliates, Microsoft will pay for all SEC filing fees, printing costs and the
fees of its counsel. We will pay all other printing costs, SEC filing fees and
the fees of counsel in connection with any Securities to be sold by any other
selling security holder. In addition, we will pay all fees, disbursements and
out-of-pocket expenses and costs incurred by us in connection with the
preparation of the registration statement of which this prospectus is a part and
in complying with all applicable securities and blue sky laws.

    A selling security holder and any broker-dealers or agents that participate
with such selling security holder in the distribution of the Securities may be
deemed to be "underwriters" within the meaning of the Securities Act, and any
commissions received by them and any profit on the resale of the Securities may
be deemed to be underwriting commissions or discounts under the Securities Act.

    We have agreed to indemnify Microsoft against certain liabilities, including
liabilities arising under the Securities Act. Microsoft may agree to indemnify
any agent, dealer or broker-dealer that participates in transactions involving
sales of the Securities against certain liabilities, including liabilities
arising under the Securities Act.

NASDAQ LISTING STATUS

"EXPE". The Expedia Warrants have been approved for quotation on the Nasdaq
National Market under the symbol "EXPEW".

(3) With respect to Microsoft Corporation, the term "selling security holder" in
    this prospectus means either Microsoft Corporation or one or more entities
    of which Microsoft Corporation holds the primary economic interest in whose

    L.P.,       shares held by TCV III (Q), L.P. and       shares held by TCV
    III Strategic Partners, L.P. (the foregoing four entities, collectively, the
    "TCV III Funds"),       shares held by TCV IV, L.P. and       shares and
    held by TCV IV Strategic Partners, L.P. (the latter two entities,
    collectively, the "TCV IV Funds" and, together with the TCV III Funds, the
    "TCV Funds"). Mr. Hoag, a director of Expedia, is a Managing Member of
    Technology Crossover Management III, L.L.C., which is the Managing General
    Partner of TCV III (GP) and the sole General Partner of TCV III, L.P., TCV

    Because the selling security holders may dispose of all or a portion of
their Securities, we cannot estimate the number of Securities that will be held

addition, a selling security holder identified above may sell, transfer or
otherwise dispose of all or a portion of its Securities in transactions exempt
from the registration requirements of the Securities Act. See "Plan of

INTERESTS OF SELLING SECURITY HOLDERS

    The following is a summary of material relationships between us and the
selling security holders and assumes consummation of the merger.

    DIRECTORS AND OFFICERS

    Certain of the selling security holders are currently directors and officers
of Expedia or were directors of Expedia prior to the consummation of the merger.

    EMPLOYMENT AGREEMENT WITH MR. BARTON.  Effective as of the effective date of
the merger, we will enter into an employment agreement with Mr. Barton setting
forth the material terms of his employment. The agreement will have a three-year
term and, six months prior to the end of the term, we and Mr. Barton will enter
into good-faith negotiations to extend the employment term. Pursuant to the
agreement, Mr. Barton will remain as chief executive officer of Expedia and will
be a member of our board of directors.

    COMPENSATION.  Mr. Barton will receive an annual base salary of $266,000 and
will be eligible to receive an annual bonus of 200% of his salary, payable 50%
in cash and 50% in Expedia stock options based on achieving agreed-upon Expedia
budget goals. $133,000 of the cash portion of Mr. Barton's bonus is guaranteed.

    Following the effective date, all of Mr. Barton's outstanding and
unexercised Expedia stock options will remain outstanding in accordance with
their terms. On the effective date, Mr. Barton will receive a grant of options
to purchase 100,000 shares of USA's common stock at a fair market value exercise
price. Mr. Barton will also receive on the effective date a grant of options to
purchase 375,000 shares of our common stock at a fair market value exercise
price. Such options have a ten-year term and will vest in four equal annual
installments commencing on the first anniversary of the effective date
contingent upon Mr. Barton's continued employment with Expedia. Mr. Barton will
also receive on the effective date an initial grant of 25,000 shares of our
restricted stock, vesting contingent upon Mr. Barton's continued employment with
Expedia through the third anniversary of the effective date. Mr. Barton will be
evaluated for future option grants in a manner consistent with similarly
situated executives of USA and its subsidiaries.

    Mr. Barton will be entitled to participate in welfare, health and life
insurance and pension benefit and incentive programs adopted by Expedia on the
same basis as similarly situated executives of Expedia, USA and their respective
subsidiaries.

                                       20

    SEVERANCE.  Upon a termination of Mr. Barton's employment by Expedia without
"cause" or by Mr. Barton for "good reason" (as each term is defined in the
agreement), we will continue to pay Mr. Barton his salary for the remainder of
the term, as well as pay any earned, but unpaid, base salary and will pay
Mr. Barton his deferred compensation balance. We will also pay Mr. Barton the
pro rata portion of his annual bonus following the end of the fiscal year of his
termination of employment (based upon satisfaction of performance goal
formulas). In addition, he will immediately vest in all options and such options
will remain exercisable for one year following his date of termination of
employment. Although Mr. Barton is not obligated to mitigate any severance
amounts, such amounts will be reduced by any compensation earned by Mr. Barton
in the event that Mr. Barton becomes employed during the remainder of the term.

    CHANGE OF CONTROL.  The agreement will provide that upon a change of control
of Expedia, all of Mr. Barton's Expedia options (and the USA options granted on
the effective date) and other Expedia equity compensation will vest immediately,
and such options will remain exercisable for one year from the date of the
change of control, notwithstanding any termination of employment.

    RESTRICTIVE COVENANTS.  The agreement will provide for Mr. Barton to be
bound by a covenant not to compete with our business (or any of our subsidiaries
or affiliates) during the term of his employment and for two years after
termination of employment for any reason; but if the non-compete period extends
beyond the severance period (under circumstances in which Mr. Barton had been
entitled to severance pay), we will pay Mr. Barton $100,000 per year (pro rated
on a monthly basis) to the extent we determine to continue the non-compete
period beyond the severance period. In addition, Mr. Barton will be bound by a
two-year covenant not to solicit our employees or customers (or any of our
subsidiaries or affiliates) and a confidentiality covenant.

    EMPLOYMENT AGREEMENT WITH MR. STANGER.  Effective as of the effective date
of the merger, we will enter into an employment agreement with Mr. Stanger
setting forth the material terms of his employment. The agreement will have a
three-year term.

    COMPENSATION.  Mr. Stanger will receive an annual base salary of $175,000
and will be eligible to receive an annual bonus of 100% of his salary, payable
50% in cash and 50% in Expedia stock options based on achieving agreed-upon
Expedia budget goals.

    Mr. Stanger will receive on the effective date an initial grant of options
to purchase 50,000 shares of our common stock at a fair market value exercise
price. Such options have a ten-year term and will vest in four equal annual
installments commencing on the first anniversary of the effective date
contingent upon Mr. Stanger's continued employment with us. Mr. Stanger will
also receive on the effective date a grant of 10,000 shares of our restricted
stock, vesting contingent upon Mr. Stanger's continued employment with us
through the third anniversary of the effective date.

    Mr. Stanger will be entitled to participate in welfare, health and life
insurance and pension benefit and incentive programs adopted by Expedia on the
same basis as similarly situated executives of Expedia, USA and their respective
subsidiaries.

    SEVERANCE.  Upon a termination of Mr. Stanger's employment by us without
"cause" or by Mr. Stanger for "good reason" (as each term is defined in the
agreement), we will continue to pay Mr. Stanger his salary for the remainder of
the term, as well as pay his earned, but unpaid, base salary and will pay
Mr. Stanger his deferred compensation balance. In addition, Mr. Stanger will
automatically and immediately vest in all of his then-outstanding equity-based
compensation awards granted on or prior to August 2, 2001, and such options
shall remain exerciseable for one year following his date of termination of
employment. Mr. Stanger is obligated to use reasonable best efforts to mitigate
any severance payable to him.

    CHANGE OF CONTROL.  The agreement will provide that upon a change of control
of Expedia, all of Mr. Stanger's Expedia options and other Expedia equity
compensation will vest immediately, and such options will remain exercisable for
one year from the date of the change of control, notwithstanding any termination
of employment.

                                       21

    RESTRICTIVE COVENANTS.  Pursuant to the agreement, Mr. Stanger will be bound
by covenants not to compete with our businesses (or our subsidiaries or
affiliates) and not to solicit our employees or customers (or our subsidiaries
or affiliates) during the term of his employment and for two years after
termination of employment for any reason. In addition, Mr. Stanger will agree
not to divulge or disclose any confidential information of Expedia or our
affiliates.

    EMPLOYMENT AGREEMENTS WITH OTHER SELLING SECURITY HOLDERS.  Effective as of
the effective date of the merger, we will also enter into employment agreements
with Mr. Bishop, Mr. Blachford, Mr. Breakwell, Mr. Britton, Mr. Day,
Ms. Dellplain, Mr. Slyngstad, as well as eight other members of our senior
management (who are not selling security holders hereunder) of Expedia and
Travelscape.com, Inc., our wholly owned subsidiary. Each of these agreements
will have a term of three years.

    Under the agreements, upon a termination of the employee's employment by us
without "cause" or a resignation by the employee with "good reason" (as each
term is defined in the term sheet), the employee will be entitled to: (a) the
acceleration and immediate vesting of all unvested Expedia options granted to
him on or prior to August 2, 2001, and any attendant warrants granted in
connection with the merger; and (b) receive the salary, target bonus and welfare
benefits (and any other damages to which he would be entitled) for the remainder
of the term, less an offset equal to any amounts earned during the term from
other employment, with no obligation to mitigate.

    As a condition to entering into the agreements, each of these employees will
agree to a non-compete for a period of one year from the date of termination for
any reason. The non-compete applies to general online travel providers such as
Travelocity, Orbitz and Priceline. Each of these individuals will also agree to
a one-year non-solicitation covenant and a standard confidentiality covenant.

    The base salaries to be provided in the employment agreements are the
individuals' respective current salary, as it may be increased during our
currently pending semi-annual performance review in a manner consistent with
past practice, unless otherwise agreed by us and USA, and subject to further
review and increase at the discretion of our chief executive officer, any such
increases to be approved by our compensation committee.

    Each individual will be entitled to participate in stock option grants after
August 2, 2001 (except that such options will not accelerate and vest upon
termination without cause or resignation with good reason).

    STOCK OPTIONS.  All options held by our non-employee directors who will not
continue as directors after the effective time, or who cease to be directors for
any reason within one year following the effective time, will become fully
exercisable.

    Pursuant to the merger agreement, each Expedia optionee, including members
of management and our board of directors, received warrants to purchase 0.1920
shares of our common stock for each Expedia option share with respect to options
issued on or prior to August 2, 2001 that were outstanding as of January   ,
2002. Each new Expedia warrant issued with respect to a stock option is subject
to the same vesting schedule as the underlying stock option. Messrs. Barton,
Stanger, Bishop, Breakwell and Slyngstad received       ,       ,       ,
      , and       warrants, respectively, and the non-employee members of the
Expedia board of directors as a group received       warrants.

    On August 2, 2001, the compensation committee of our board of directors
issued an aggregate of 1,509,145 options to acquire shares of our common stock
pursuant to the Expedia 1999 Stock Option Plan and the Expedia 1999 Amended and
Restated Stock Option Plan for Non-Employee Directors, at exercise prices of
$44.55 and $48.70.

    As part of this grant, we granted to Messrs. Barton, Stanger, Bishop,
Breakwell and Slyngstad 125,000, 50,000, 25,000, 25,000 and 50,000 stock
options, respectively. Mr. Maffei was granted 100,000 stock options and each of
the remaining non-employee directors was granted 5,000 stock options on such
date. As noted above, provided that these options were outstanding as of
January   , 2002, these

                                       22

holders were entitled to receive the warrants in respect of their options on the
same terms as described above.

    USA STOCK OPTIONS.  The Compensation Committee of USA has granted options to
acquire USA common stock, which included grants to Expedia executives.
Specifically, USA granted, effective upon completion of the merger, to Messrs.
Barton, Stanger, Bishop, Breakwell and Slyngstad options to acquire 100,000,
70,000, 30,000, 30,000 and 30,000 shares of USA common stock, respectively. USA
also granted, effective upon completion of the merger, options to acquire 30,000
shares of USA common stock to each of four other executive officers of Expedia.
All of the options will vest in four equal installments on the first four
anniversaries of the closing, and the per share exercise price of each option
will be the closing sales price of USA common stock on the last market trading
day prior to completion of the merger.

    OUR RELATIONSHIP WITH MICROSOFT

    In October 1996, Microsoft launched its online travel services through
Expedia. On October 1, 1999, Microsoft separated the Expedia assets and
contributed them to us in exchange for 33,000,000 shares of common stock or 100%
of our outstanding common stock at that date. As a result of the merger
transactions, Microsoft no longer owns a controlling interest in Expedia.

    At the time of our separation from Microsoft in 1999, Microsoft assigned to
us a number of contracts having to do with the Expedia business. Many of these
have intellectual property components. Generally, where the contract only
impacted our business and no other units of Microsoft, it was assigned to us. To
our knowledge, Microsoft obtained all necessary consents to these assignments
where applicable.

    At the time of our separation from Microsoft, we also entered into a number
of other agreements with Microsoft that were necessary to separate our assets
from Microsoft and to facilitate the operation of our assets after such
separation. As part of the merger transactions, each of the agreements relating
to our separation from Microsoft has been amended and restated. Each of these
agreements is summarized below.

AMENDED AND RESTATED CARRIAGE AND CROSS PROMOTION AGREEMENT.

    In June 2001, we and Microsoft entered into an amended and restated carriage
and cross promotion agreement. Under this agreement, Microsoft's domestic and
international MSN websites promote co-branded versions of our websites that
include the logos of both Expedia and MSN in the United States, the United
Kingdom, Germany and Canada, countries in which we are currently present. These
co-branded websites are the preferred travel transaction services offered on
MSN, except in international markets where we do not have a presence. Under the
agreement, we and Microsoft also agreed to certain restrictions regarding the
promotion of competitors on MSN.com and on the MSN Expedia co-branded travel
websites accessed via MSN.com. The amended and restated agreement has a
four-year term.

    We pay Microsoft slotting fees and performance fees under the amended and
restated carriage and cross promotion agreement. These fees are calculated in
accordance with the terms of the agreement and, in certain cases, a letter
agreement entered into by us and Microsoft in July 2001.

    We pay Microsoft an annual slotting fee of $500,000 for the U.S. co-branded
travel website. This fee is credited toward the performance fees that we are
required to pay Microsoft. We pay Microsoft an annual slotting fee of $250,000
for each non-U.S. co-branded travel website. These fees are credited towards the
performance fees we are required to pay Microsoft only if these non-U.S.
websites exceed specified revenue targets. The performance fees we pay to
Microsoft are based on the number of transactions of each transaction type that
occur on the co-branded websites multiplied by the average gross profit per
transaction achieved by us for each transaction type multiplied by the agreed
percentage of gross profit to be shared for each transaction type.

                                       23

AMENDED AND RESTATED SERVICES AGREEMENT.

    On October 1, 1999, we and Microsoft entered into a services agreement
whereby Microsoft agreed to provide us with certain administrative and
operational services. This agreement was subsequently amended and restated
effective January 1, 2001 and further amended effective July 1, 2001. In
connection with the merger, the agreement was again amended and restated
effective December 21, 2001.

    Under the current agreement, Microsoft will continue to provide us with
specified administrative and operational services. In return, we will pay
Microsoft fees based on the total direct and indirect costs incurred by
Microsoft in providing these services to us. The current agreement is effective
through September 30, 2002. The agreement is cancelable by us upon 30 days
written notice and, in limited circumstances, by Microsoft upon 180 days written
notice. The agreement also provides that Microsoft may terminate specified
services if it determines in good faith, after consultation with us and USA,
that it is inappropriate for Microsoft to continue providing these services to
an unaffiliated third party. We have been developing and will continue to
develop our own resources in these areas and currently intend to discontinue
some or all of the services provided by Microsoft before the end of the current
agreement.

HOSTING SERVICES AGREEMENT.

    On August 14, 2001, in connection with the merger transactions, we and
Microsoft entered into a hosting services agreement under which Microsoft
provides us with internet service provider services for our websites. Microsoft
previously provided these services to us under the amended and restated services
agreement. The hosting services agreement has a four-year term. We pay Microsoft
for the hosting services on a cost basis.

LICENSE AGREEMENTS.

    On October 1, 1999, we and Microsoft entered into a license agreement under
which Microsoft provides us with rights to intellectual property used in its
business. Microsoft assigned to us the trademarks and domain names associated
with the name "Expedia." In addition, Microsoft assigned to us copyrights for
software relating to online travel services.

    Under the license agreement, we licensed the right to use some of
Microsoft's retail products and other technology under the license agreement
with Microsoft. All of the licenses relating to Expedia specific software
content and data and patents were royalty-free, irrevocable and perpetual. In
connection with the merger transactions, the license agreement was terminated,
however, the perpetual licenses remain in effect.

    On September 25, 2001, we and Microsoft entered into the following
agreements that provide us with worldwide rights to use some of Microsoft's
retail products: Microsoft Business Agreement; Microsoft Enterprise Agreement;
Microsoft Enterprise Enrollment Agreement; Microsoft Select Agreement; and
Microsoft Select Enrollment Agreement to replace some of the licenses in the
license agreement dated October 1, 1999.

AMENDED AND RESTATED MAP SERVER LICENSE AGREEMENT.

    On October 1, 1999, we and Microsoft entered into a map server agreement
under which Microsoft licenses to us certain server technology related to the
Expedia Maps service. In connection with the merger transactions, we and
Microsoft entered into an amended and restated map server license agreement
effective August 15, 2001 to amend some of the terms under which Microsoft
provides us with such technology.

    Under the amended and restated map server license agreement, Microsoft will
develop, maintain, host and serve maps to our websites. This agreement has a
four-year term. The maps will be

                                       24

customized for our websites and will include both our logo and Microsoft's
MapPoint.Net logo. We have agreed to pay Microsoft on a per transaction basis
for each map served.

AGREEMENT TO ASSIGN PATENT APPLICATIONS AND ROYALTY SHARING AGREEMENT.

    On November 6, 2001, we entered into an assignment agreement with Microsoft
pursuant to which Microsoft assigned to us all of Microsoft's patents relating
to the operation of our websites. The assignment agreement includes a limited
license of such patents from us to Microsoft. Further, the assignment agreement
includes a royalty sharing arrangement under which we will pay a percentage of
any royalties collected by us to Microsoft for licenses to such patents that are
granted by us to third parties for use in products and/or services other than
online travel services.

AMENDED AND RESTATED REGISTRATION RIGHTS AGREEMENT.

    On July 15, 2001, in connection with the merger transactions, we entered
into a registration rights agreement with Microsoft. This agreement was
subsequently amended and restated. Under the amended and restated agreement, we
agreed to grant to Microsoft customary registration rights, including the right
to underwritten offerings, relating to our securities, if any, owned by
Microsoft following completion of the merger transactions. We agreed to file the
registration statement, of which this prospectus forms a part, with respect to
Microsoft's Expedia securities and to use our reasonable best efforts to make
this registration statement effective as promptly as practicable following the
completion of the merger transactions.

TAX ALLOCATION AGREEMENT.

    Effective October 1, 1999, we entered into a tax allocation agreement with
Microsoft. For periods during which we were included in Microsoft's consolidated
U.S. federal tax return, the agreement generally adopts the "percentage of tax
liability" method of Regulations section 1.1552-1(a)(2) as its "basic method"
and the "percentage" method of Regulations section 1.1502-33(d)(3) as its
complementary method.

    Under the "percentage of tax liability" method, a member's allocable share
of consolidated tax liability is equal to the tax liability of the group
multiplied by a fraction, the numerator of which is the separate return tax
liability of such member and the denominator of which is the sum of the separate
return tax liability of all the members.

    This basic allocation method is modified by the complementary "percentage"
method. Under the percentage method, in the event a loss or credit is generated
by a member, such member is compensated at the time the loss or credit is
absorbed by the other members of the Microsoft group. In our case, however, 7.5%
of the benefit Expedia generates and is absorbed by the other members of the
Microsoft group will be retained by Microsoft as a "fee" because Expedia is
being paid for tax attributes prior to the time we could have used them to
reduce our tax liability.

    We may be reimbursed by Microsoft for tax losses incurred during the period
from October 1, 1999 to March 17, 2000 which are utilized on the Microsoft
consolidated U.S. federal tax return. On March 18, 2000, Microsoft's investment
in Expedia fell below 80% ownership. As such, from March 18, 2000 onward, we
must file a separate tax return. Any losses not utilized by Microsoft during the
period that we were included in Microsoft's consolidated return will be carried
forward by us and can be used on our separate return to offset any future
taxable income.

    Under the terms of this agreement, Microsoft is entitled to the benefit of
the compensation deduction attributable to the Microsoft stock options that we
assumed at the time of our initial public offering. We and Microsoft take this
deduction into account under the normal tax accounting rules, so the deduction
generally occurs on the exercise of the options. The portion of this cost that
Microsoft deducts is equal to the excess of the fair market value of the shares
to be acquired on exercise of the option on the date we employ the optionee over
the exercise price of the assumed option. We determined this amount on the date
that we employed each optionee.

                                       25

    We agreed in the merger agreement that the aggregate liability of Expedia to
make payments after the date of the merger agreement to no more than $36,300,000
with respect to any past, present or future taxable periods. In addition, we
agreed that the term "Inherent Bargain Element," as used in the Microsoft tax
allocation agreement, will not include any amount with respect to any option to
purchase Expedia common stock granted on or after July 15, 2001. Microsoft has
also agreed to indemnify and hold harmless USA and Expedia for certain tax
liabilities.

    On November 9, 2001, we entered into an agreement with Microsoft setting
forth the manner in which we are to compensate Microsoft for the compensation
deductions attributable to the "Inherent Bargain Element" as used in the
Microsoft tax allocation agreement. Under this agreement, we will be required to
compensate Microsoft for the actual federal and state tax savings that we
realize as a result of the use of the compensation deductions, as and when we
realize such tax savings.

                                       26

                          DESCRIPTION OF CAPITAL STOCK

    Set forth below is a description of our capital stock and assumes
consummation of the merger. The following statements are brief summaries of, and
are subject to the provisions of, our amended and restated articles of
incorporation and amended and restated bylaws, the warrant agreements relating
to the Expedia Warrants and the relevant provisions of the Business Corporations
Act of the State of Washington.

GENERAL

    We are authorized to issue up to 770,000,000 shares of capital stock,
consisting of 600,000,000 shares of common stock, par value $.01 per share,
150,000,000 shares of Class B common stock, par value $.01 per share, and
20,000,000 shares of preferred stock, par value $.01 per share. As of
  , 2002, assuming exercise of all Expedia Warrants, there were outstanding
approximately             shares of Expedia common stock,             shares of
Expedia Class B common stock and no shares of Expedia preferred stock. If
preferred stock is issued, our Board of Directors may fix the designation,
relative rights, preferences and limitations of the shares of each series.

COMMON STOCK AND CLASS B COMMON STOCK

    As a result of the merger, we have a "dual class" common stock structure,
consisting of common stock and Class B common stock. The rights and preferences
of the common stock and the Class B common stock are identical to each other,
except that holders of Class B common stock are entitled to 15 votes per share,
compared with one vote per share for the common stock; provided that if at any
time a person and its affiliates would hold in aggregate more than 94.9% of our
aggregate voting power, then the number of votes for each share of Class B
common stock shall be reduced pursuant to the following formula:


                                                              
                                             (0.949w--v)
                               v         =
                                             ----------
                                             (z--0.949x)


        where v = votes per share of Class B common stock held by the person

           w = total number of outstanding shares of common stock;

           x = total number of outstanding shares of Class B common stock;

           y = total number of outstanding shares of common stock held by the
       person; and

           z = total number of outstanding shares of Class B common stock held
       by the person,

    provided, further, that (1) subject to clause (3) below, in no event shall
the application of the formula result in the aggregate voting power of a person
being less than or greater than 94.9% of our aggregate voting power, (2) our
Board of Directors shall be authorized to adjust the formula set forth in the
first proviso of this paragraph in the event that there are outstanding any
voting securities of Expedia other than the common stock and the Class B common
stock, as appropriate, to provide that, subject to clause (3) of this proviso,
the aggregate voting power of the person is not greater than or less than 94.9%
of our aggregate voting power, and (3) in the event that pursuant to the formula
in the first proviso of this paragraph (as adjusted from time to time pursuant
to clause (2) of this proviso), the votes per share of Class B common stock held
by the person either (A) cannot be determined or (B) would be a negative number,
in each case, which occurs when that person owns more than 94.9% of the
outstanding common stock as well as 94.9% or more of the Class B common stock,
the first proviso of this paragraph shall be disregarded and be of no further
force and effect and each share of Class B common stock shall be entitled to
fifteen (15) votes per share.

                                       27

    No holders of either class of our common stock have cumulative voting
rights, preemptive or conversion rights. There are no redemption or sinking fund
provisions available to either class of common stock. All outstanding shares of
each class of common stock are fully-paid and non-assessable. Taking into
consideration preferences that may be applicable to any then-outstanding Expedia
preferred stock, holders of either class of common stock will be entitled to
receive ratably any dividends that may be declared by the board of directors of
Expedia out of funds legally available for these dividends. In the event of a
liquidation, dissolution or winding up of Expedia, holders of either class of
common stock will be entitled to share ratably in all assets remaining after
payment of liabilities and any liquidation preference to any then-outstanding
holders of Expedia preferred stock.

EXPEDIA WARRANTS

    Expedia Employee Warrants were issued to our option holders under a warrant
agreement between Expedia and Mellon Investor Services LLC, as warrant agent. A
copy of the Expedia Employee Warrant agreement has been filed with the SEC as an
exhibit to the Form S-3 registration statement. On January 25, 2002, we
distributed an aggregate of       Expedia Employee Warrants to certain of our
optionholders. As of           , 2002, there were     Expedia Employee Warrants
outstanding.

    Expedia Shareholder Warrants were issued to our option holders under a
warrant agreement between Expedia and Mellon Investor Services LLC, as warrant
agent. A copy of the Expedia Shareholder Warrant agreement has been filed with
the SEC as an exhibit to the Form S-4 registration statement. In connection with
the merger, we issued an aggregate of     Expedia Shareholder Warrants to
shareholders who retained their shares of Expedia common stock in the
recapitalization. As of           , 2002, there were     Expedia Shareholder
Warrants outstanding.

    The Expedia Warrants expire on         , 2009. Each Expedia Warrant entitles
its holder to purchase one share of Expedia common stock at any time prior to
        , 2009 upon payment of the exercise price of $52.00 per share, subject
to adjustment. The exercise price must be paid in cash. Any Expedia Warrant not
exercised on or prior to the last business day before the expiration of this
period will become void, and all rights of the holder of the Expedia Warrant
will cease. Holders of Expedia Warrants will not be entitled, by virtue of being
such holders, to have any rights of holders of Expedia common stock until they
exercise their warrants. The Expedia Warrants are not subject to redemption.

    The number of shares of Expedia common stock issuable upon exercise of the
Expedia Warrants and the exercise price of the Expedia Warrants are subject to
adjustment from time to time upon the occurrence of any of the following events
to the Expedia common stock: any stock split; any stock consolidation,
combination or subdivision; any stock dividend or other distribution; any
repurchase, reclassification, recapitalization or reorganization; and certain
distributions of rights, warrants or evidences of indebtedness or assets.

    We will keep in reserve at all times before the expiration date of the
Expedia Warrants sufficient authorized but unissued shares of Expedia common
stock for issuance in the event of exercises by the holders of Expedia Warrants.
In addition, the Expedia Warrants and any shares of Expedia common stock
issuable upon exercise of the Expedia Warrants will be registered under the
Securities Act.

TRANSFER AGENT

    The transfer agent for our common stock is Mellon Investor Services LLC.

                                       28

                MATERIAL UNITED STATES FEDERAL TAX CONSEQUENCES

GENERAL

    The following is a general discussion of the material United States federal
income and estate tax consequences of the ownership and disposition of Expedia
Warrants and Expedia common stock received upon exercise of Expedia Warrants.
This discussion is based on current law, which is subject to change, possibly
with retroactive effect, or different interpretations. This discussion is
limited to holders who hold Expedia Warrants or shares of Expedia common stock
as capital assets. Moreover, this discussion is for general information only and
does not address all the tax consequences that may be relevant to you in light
of your personal circumstances, such as banks, insurance companies, dealers in
securities or currencies, tax-exempt entities, persons that will hold Expedia
Warrants or Expedia common stock as a position in a "straddle" or as part of a
"hedging" or "conversion" transaction for tax purposes, and persons that have a
"functional currency" other the U.S. dollar. Nor does this discussion discuss
special tax provisions that may apply to you if you relinquished United States
citizenship or residence.

    A United States Holder is the beneficial owner of Expedia Warrants or
Expedia common stock that is (i) an individual citizen or resident of the United
States; (ii) a corporation, partnership or other entity created or organized
under the laws of the United States or any political subdivision thereof;
(iii) an estate, the income of which is subject to United States federal income
taxation regardless of its sources; (iv) a trust if a court in the United States
is able to exercise primary supervision and one or more United States persons
have the authority to control all substantial decisions or if the trust has made
a valid election to be treated as a United States person under applicable
Treasury Regulations.

    A non-United States Holder is a beneficial owner of Expedia Warrants or
Expedia common stock that is not a United States Holder. If you are an
individual, you may, in many cases, be deemed to be a resident alien, as opposed
to a nonresident alien, by virtue of being present in the United States for at
least 31 days in the calendar year and for an aggregate of at least 183 days
during a three-year period ending in the current calendar year. For these
purposes all the days present in the current year, one-third of the days present
in the immediately preceding year, and one-sixth of the days present in the
second preceding year are counted.

    EACH PROSPECTIVE RECIPIENT OR PURCHASER OF EXPEDIA WARRANTS OR EXPEDIA
COMMON STOCK IS ADVISED TO CONSULT A TAX ADVISOR WITH RESPECT TO CURRENT AND
POSSIBLE FUTURE TAX CONSEQUENCES OF PURCHASING, OWNING AND DISPOSING OF OUR
COMMON STOCK OR WARRANTS AS WELL AS ANY TAX CONSEQUENCES THAT MAY ARISE UNDER
THE LAWS OF ANY UNITED STATES STATE, MUNICIPALITY OR OTHER TAXING JURISDICTION.

UNITED STATES HOLDERS

    EXERCISE OF EXPEDIA WARRANTS AND OWNERSHIP OF EXPEDIA COMMON STOCK.  Upon
the exercise of an Expedia Warrant, as a United States Holder, you will not
recognize gain or loss (except to the extent of cash, if any, received in lieu
of the issuance of fractional shares of Expedia common stock minus the portion
of the adjusted tax basis of the Expedia Warrant and the portion of the exercise
price allocable to such fractional shares), and you will have an adjusted tax
basis in the Expedia common stock acquired pursuant to such exercise equal to
your adjusted tax basis in the Expedia Warrant plus the exercise price of the
Expedia Warrant minus the portion of such amounts attributable to fractional
shares. Your holding period for such Expedia common stock so acquired will
commence on the date after the date of exercise of the Expedia Warrant. Any gain
or loss recognized as a result of receiving cash in lieu of fractional shares of
Expedia common stock will be in an amount and of the same character that you
would have recognized if you had received such fractional shares and then
immediately sold them for cash back to the Company. Upon the sale of Expedia
common stock

                                       29

received upon exercise of an Expedia Warrant, you will recognize capital gain or
loss equal to the difference between the amount realized upon the sale and your
adjusted tax basis in the common stock. Distributions made with respect to the
Expedia common stock will constitute dividends to the extent paid out of our
current or accumulated earnings and profits. To the extent that a distribution
exceeds our earnings and profits, it will be treated as a nontaxable return of
the capital to the extent of your adjusted tax basis in the Expedia common stock
and the excess, if any, will be treated as capital gain.

    SALE OR LAPSE OF EXPEDIA WARRANTS.  You will recognize capital gain or loss
on the sale of an Expedia Warrant in an amount equal to the difference between
the amount realized and your tax basis in the Expedia Warrant. If an Expedia
Warrant expires unexercised, you will recognize a capital loss equal to your tax
basis in the Expedia Warrant.

    ADJUSTMENTS.  Under Section 305 of the Internal Revenue Code, adjustments to
the exercise price or conversion ratio of the Expedia Warrants which occur under
certain circumstances, or the failure to make such adjustments, may result in
the receipt of taxable constructive dividends by you (subject to a possible
dividends received deduction in the case of corporate United States Holders) to
the extent of our current or accumulated earnings and profits, regardless of
whether there is a distribution of cash or property.

    INFORMATION REPORTING AND BACKUP WITHHOLDING TAX.  In general, information
reporting requirements and backup withholding requirements will apply to the
payments of dividends on Expedia common stock paid to you and payments of
proceeds of the sale of your Expedia common stock. You may avoid backup
withholding by properly executing under penalties of perjury an Internal Revenue
Service Form W-9 or substantially similar form that provides (i) your correct
taxpayer identification number, and (ii) certification that (A) you are exempt
from backup withholding because you are a corporation or come within another
enumerated exempt category, (B) you have not been notified by the Internal
Revenue Service that you are subject to backup withholding, or (C) you have been
notified by the Internal Revenue Service that you are no longer subject to
backup withholding.

    Unless you have established on a properly executed Internal Revenue Service
Form W-9 or substantially similar form that you are a corporation or come within
another enumerated exempt category, dividends on Expedia common stock paid to
you during the calendar year, and the amount of tax withheld, if any, will be
reported to you and to the Internal Revenue Service. Amounts withheld are
generally not an additional tax and may be refunded or credited against your
United States federal income tax liability, provided you furnish the required
information to the Internal Optionholder Revenue Service.

NON-UNITED STATES HOLDERS

    DIVIDENDS.  If dividends (including constructive dividends under
Section 305 of the Internal Revenue Code) are paid on shares of Expedia common
stock, as a non-United States Holder, you will be subject to withholding of
United States federal income tax at a 30% rate or a lower rate as may be
specified by an applicable income tax treaty. To claim the benefit of a lower
rate under an income tax treaty, you must properly file with the payor an
Internal Revenue Service Form W-8BEN, or successor form, claiming an exemption
from or reduction in withholding under the applicable tax treaty. In addition,
where dividends are paid to a non-United States Holder that is a partnership or
other pass through entity, persons holding an interest in the entity may need to
provide certification claiming an exemption or reduction in withholding under
the applicable treaty.

    If dividends are considered effectively connected with the conduct of a
trade or business by you within the United States and, where a tax treaty
applies, are attributable to United States permanent establishment of yours,
those dividends will not be subject to withholding tax, but instead will be
subject to United States federal income tax on a net basis at applicable
graduated individual or

                                       30

corporate rates, provided an Internal Revenue Service Form W-8ECI, or successor
form, is filed with the payor. If you are a foreign corporation, any effectively
connected dividends may, under certain circumstances, be subject to an
additional "branch profits tax" at a rate of 30% or a lower rate as may be
specified by an applicable income tax treaty.

    You must comply with the certification procedures described above, or, in
the case of payments made outside the United States with respect to an offshore
account, certain documentary evidence procedures, directly or under certain
circumstances through an intermediary, to obtain the benefits of a reduced rate
under an income tax treaty with respect to dividends paid with respect to your
Expedia common stock. In addition, if you are required to provide an Internal
Revenue Service Form W-8ECI or successor form, as discussed above, you must also
provide your tax identification number.

    If you are eligible for a reduced rate of United States withholding tax
pursuant to an income tax treaty, you may obtain a refund of any excess amounts
withheld by filing an appropriate claim for refund with the Internal Revenue
Service.

    GAIN ON DISPOSITION OF EXPEDIA WARRANTS OR COMMON STOCK.  As a non-United
States Holder, you generally will not be subject to United States federal income
tax on any gain recognized on the sale or other disposition of Expedia Warrants
or Expedia common stock unless:

1.  the gain is considered effectively connected with the conduct of a trade or
    business by you within the United States and, where a tax treaty applies, is
    attributable to a United States permanent establishment of yours (and, in
    which case, if you are a foreign corporation, you may be subject to an
    additional branch profits tax equal to 30% or a lower rate as may be
    specified by an applicable income tax treaty).

2.  you are an individual who holds the Expedia Warrants or Expedia common stock
    as a capital asset and are present in the United States for 183 or more days
    in the taxable year of the sale or other disposition and other conditions
    are met; or

3.  we are or have been a "United States real property holding corporation," or
    a USRPHC, for United States federal income tax purposes. We believe that we
    are not currently, and are not likely not to become, a USRPHC. If we were to
    become a USRPHC, then gain on the sale or other disposition of Expedia
    Warrants or Expedia common stock by you generally would not be subject to
    United States federal income tax provided:

       a.  the Expedia Warrants or Expedia common stock was "regularly traded on
           an established securities market; and

       b.  you do not actually or constructively own more than 5% of the Expedia
           common stock during the shorter of the five-year period preceding the
           disposition or your holding period.

    FEDERAL ESTATE TAX.  If you are an individual, Expedia Warrants or Expedia
common stock held at the time of your death will be included in your gross
estate for United States federal estate tax purposes, and may be subject to
United States federal estate tax, unless an applicable estate tax treaty
provides otherwise.

    INFORMATION REPORTING AND BACKUP WITHHOLDING TAX.  We must report annually
to the Internal Revenue Service and to each of you the amount of dividends paid
to you and the tax withheld with respect to those dividends, regardless of
whether withholding was required. Copies of the information returns reporting
those dividends and withholding may also be mad available to the tax authorities
in the country in which you reside under the provisions of an applicable income
tax treaty or other applicable agreements.

                                       31

    Backup withholding is generally imposed on certain payments to persons that
fail to furnish the necessary identifying information to the payor. You
generally will be subject to back-up withholding tax with respect to dividends
paid on your Expedia common stock unless you certify your non-United States
status.

    The payment of proceeds of a sale of Expedia Warrants or Expedia common
stock effected by or through a United States office of a broker is subject to
both backup withholding and information reporting unless you provide the payor
with your name and address and you certify your non-United States status or you
otherwise establish an exemption. In general, backup withholding and information
reporting will not apply to the payment of the proceeds of a sale of Expedia
Warrants or Expedia common stock by or through a foreign office of a broker. If,
however, such broker is, for United States federal income tax purposes, a United
States person, a controlled foreign corporation, a foreign person that derives
50% or more of its gross income for certain periods from the conduct of a trade
or business in the United States, or, a foreign partnership that at any time
during its tax year either is engaged in the conduct of a trade or business in
the United States or has as partners one or more United States persons that, in
the aggregate, hold more than 50% of the income or capital interest in the
partnership, such payments will be subject to information reporting, but not
backup withholding, unless such broker has documentary evidence in its records
that you are a non-United States Holder and certain other conditions are met or
you otherwise establish an exemption.

    Any amounts withheld under the backup withholding rules generally will be
allowed as a refund or a credit against your United States federal income tax
liability provided the required information is furnished in a timely manner to
the Internal Revenue Service.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Article VII of our Articles of Incorporation authorizes us to indemnify any
present or former director or officer to the fullest extent not prohibited by
the Washington Business Corporation Act ("WBCA") or other applicable law now or
hereafter in force. Chapter 23B.08.510 and .570 of the WBCA authorizes a
corporation to indemnify its directors, officers, employees, or agents in terms
sufficiently broad to permit such indemnification under specific circumstances
for liabilities, including provisions permitting advances for expenses incurred,
arising under the Securities Act of 1933, as amended (the "Securities Act").

    In addition, we maintain directors' and officers' liability insurance under
which our directors and officers are insured against loss, as defined in the
policy, as a result of claims brought against them for their wrongful acts in
such capacities.

ITEM 17. UNDERTAKINGS

    The undersigned registrant hereby undertakes:

    (1)  To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

        (a)  To include any prospectus required by section 10(a)(3) of the
    Securities Act;

        (b)  To reflect in the prospectus any facts or events arising after the
    effective date of this registration statement (or the most recent
    post-effective amendment thereof) which, individually or in the aggregate,
    represent a fundamental change in the information set forth in this
    registration statement. Notwithstanding the foregoing, any increase or
    decrease in volume of securities offered (if the total dollar value of
    securities offered would not exceed that which was registered) and any
    deviation from the low or high end of the estimated maximum offering range
    may be reflected in the form of prospectus filed with the SEC pursuant to
    Rule 424(b) if, in the aggregate, the changes in volume and price represent
    no more than a 20% change in the maximum aggregate offering price set forth
    in the "Calculation of Registration Fee" table in the effective registration
    statement;

        (c)  To include any material information with respect to the plan of
    distribution not previously disclosed in this registration statement or any
    material change to such information in this registration statement.

    (2)  That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial BONA FIDE offering
thereof.

    (3)  To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

    (4)  For purposes of determining any liability under the Securities Act,
each filing of the registrant's annual report pursuant to Section 13(a) or
Section 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act") (and, where applicable, each filing of an employee benefit plan's annual
report pursuant to Section 15(d) of the Exchange Act) that is incorporated by
reference in the registration statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial BONA FIDE offering
thereof.

    (5)  Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the SEC such indemnification is against
public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the registrant of expenses incurred or
paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue

                                      II-2

                                   SIGNATURES
