Northwest Airlines, Inc. and PRICELINE
-------------------------------------------------------------------------------

          THIS AIRLINE PARTICIPATION AGREEMENT ("Agreement'), dated October
2,1998, is by and among NORTHWEST AIRLINES, INC., a Minnesota corporation, with
its principal place of business at 5101 Northwest Drive, St. Paul, MN 5111-3034
(the "Airline"), and priceline.com Incorporated, a Delaware limited liability
company with an address at 5 High Ridge Park, Stamford, Connecticut 06905
("priceline.com"), and PriceLine Travel, Inc., a Delaware corporation with an
address at 5 High Ridge Park, Stamford, Connecticut 06905 ("PriceLine Travel
and, together with priceline.com, being collectively referred to herein as
"PriceLine")

                                   WITNESSETH

          WHEREAS, PriceLine provides an electronic service via the Internet
that allows consumers to purchase airline tickets at an offer price determined
by the consumer (the "PriceLine Service"). The consumer identifies the origin
and destination and departure and return dates for travel and the price the
consumer is willing to pay for the travel. PriceLine then determines if seats
are available at an appropriate price. If such seats are available, PriceLine
Travel will issue a ticket on the applicable carrier.

          WHEREAS, The Airline desires to participate in the PriceLine Service
and, in connection therewith, will provide access to the Airline's inventory at
pricing for the origin and destination pairs (each, an "O&D") as determined by
the Airline in accordance with the terms and conditions set forth in this
Agreement.

          WHEREAS, PriceLine desires to include the Airline as a participating
carrier in the PriceLine Service and to have access to such inventory in
accordance with the terms and conditions set forth in this Agreement.

          NOW, THEREFORE, in consideration of the covenants and agreements set
forth in this Agreement, the parties agree as follows:

Northwest Airlines, Inc. and PRICELINE
-------------------------------------------------------------------------------

          1.1 The Airline shall make available to PriceLine inventory and
pricing of O&Ds as determined by the Airline in accordance with the terms and
conditions set forth in this Agreement. As such, for each O&D that the Airline

Unpublished Fare consisting of the base fare and the federal excise tax
applicable thereto pursuant to sections 4261(a) and 4261(e)(5) of the Internal
Revenue Code of 1986, as amended (the "Code"), or any successor provisions (the
"Unpublished Fare"). It is expressly understood and agreed that the Airline
makes no commitment whatsoever, regarding the level of inventory, the number of
such O&Ds or the level of specific pricing of Unpublished Fares, except that,
when any Unpublished Fares are made available, such will be communicated by the
Airline to PriceLine under the procedures identified in Attachment A, annexed
hereto and made a part hereof. Availability of seats is at the sole discretion
of the Airline, and any inventory communicated to PriceLine may be decreased or
withdrawn by Airline at any time before a sale thereof by PriceLine

     travel permitted;

               1.2.3 Frequent Flyer mileage and upgrades will not be permitted;

     PriceLine Tickets;

               1.2.4 PriceLine customers must agree to (i) make at least one
     stop or connection on both their departing and return flights, (ii) accept

     the specified date of travel (x) for domestic U.S. flights, during the 6

     has specified a request to

               1.2.8 In any 72-hour period, a PriceLine customer shall be
     limited to making one offer price for airline ticket(s) for a Trip. A
     "Trip" is defined as travel between the same airports on the same dates of
     travel by the persons identified in the previous subparagraph hereof. A
     PriceLine customer may, within said 72-hour period, make an offer for
     travel in a different airport pair, in the same airport pair, or on a
     different date of travel.

               1.2.9 PriceLine Travel, and not the Airline, shall be solely

customer via the Internet (or through PriceLine's customer service
representatives if the customer contacts PriceLine through its toll free
customer service number), and will be set forth on ticketing and/or itinerary
documentation issued by PriceLine Travel.

          1.6 All PriceLine Tickets issued for carriage on Airline shall be
subject to the published conditions of carriage and the fare rules of Airline.
Airline will honor all PriceLine Tickets issued for travel on Airline in
accordance with the Restrictions and other rules and conditions established by
Airline for PriceLine Tickets, which are set forth in Attachment A hereto, as
the same may be supplemented by Airline in its discretion from time to time.

          1.7 The Airline will provide transportation for PriceLine customers in
accordance with its general conditions for carriage except as noted in Section
1.2 above. Any special handling procedures will be drafted by the parties and
made a supplement hereto.

telephone service center that will respond to any consumer questions and issues
pertaining to special handling requirements for PriceLine Tickets, including
processing any customer handling requirements as identified and authorized by
the Airline.

          1.8 At the request of Airline, PriceLine will, at its own cost and
expense, incorporate into the PriceLine Service a "hot link" to the designated
Internet site of Airline: provided however, that PriceLine will have a
reasonable period of time following any such request to accomplish any system
changes, additions or enhancements necessary or appropriate for the inclusion of
any such "hot link".

          2.1 PriceLine and the Airline will each hold in confidence and,
without the prior written consent of the other, will not reproduce, distribute,
transmit, transfer or disclose, directly or indirectly, in any form, by any
means or for any purpose, any Confidential Information of the other. As used
herein, the term "Confidential Information" shall mean this Agreement and its
subject matter, and information that is provided to or obtained from one party
to the other party and that is valuable to the disclosing party, and
particularly any information which derives economic value, actual or potential,
from not being generally known to, and not generally ascertainable by proper
means by, other persons who can obtain economic value from its disclosure or
use. The recipient of Confidential Information may only disclose such
information to its employees on a need-to-know basis. The obligations of a
recipient party with respect to Confidential Information shall remain in effect
during and after the term of this Agreement (including any renewals or
extensions hereof, and as otherwise further clarified in Section 2.3 hereof)
except to the extent necessary to comply with applicable law or the order or
other legal process of any court, governmental or similar authority having

commercial care in protecting the confidentiality of the other party's
Confidential Information.

(including any renewals or extensions hereof) and for a period of three (3)
years thereafter, except to the extent such data:

               2.3.1 is or becomes generally available to the public other than

     employees, agents or advisors;

     provided that such source is not bound by any confidentiality obligations
     to the disclosing party or its affiliated companies (as applicable); or

               2.3.3 is necessary to comply with applicable law or the order or
     other legal process of any court, governmental or similar authority having
     jurisdiction over the recipient.

          2.4 In the event that the recipient becomes legally compelled to
disclose any of such Confidential Information by any governmental body or court,
recipient will provide the disclosing party with prompt notice so that the
disclosing party may seek a protective order or other appropriate remedy and/or
waive compliance (in writing) with provisions hereof. In the event that such
protective order or other remedy is not obtained, or the disclosing party waives
(in writing) compliance with the provisions hereof, recipient will furnish only
that portion of such Confidential Material which is legally required and will
exercise its reasonable business efforts to obtain appropriate assurance that
confidential treatment will be accorded such Confidential Information.

Service.

          2.6 PriceLine will not identify the Airline's participation to the
bidder in any specific O&D until a customer is booked and confirmed for
ticketing. Further, PriceLine will not, in any media, indicate that the Airline
is participating or has participated in any specific O&D except to indicate
that, as a consumer proposition, a PriceLine customer must accept a routing on
one of the major U.S. full service airlines or, in the case of international
travel, other airline carriers available through the PriceLine Service. The
Airline may be identified, in such case and for definitional purposes, as one
of the major U.S. full service airlines. Beyond such identification, PriceLine
will not otherwise advertise or promote that Airline is a participant in the
PriceLine Program.

The Airline shall maintain and communicate any changes in fares and/or rules to
be used by PriceLine. The Airline will file base fares (i.e. not fares) via
ATPCO (Airline Tariff Publishing Corporation). The base fare is the Unpublished
Fare net of any taxes required to be paid by a customer as part of the purchase
of a ticket from PriceLine under Section 4261(a) and 4261(e)(5) of the Code.
ATPCO will transmit the base fares to WorldSpan and WorldSpan will add in the
Section 4261 Taxes. These fares will be secured to the PriceLine IATA number.

The Airline may file fare and/or rule changes up to 3 times a day Mon-Fri and
once a day on weekends. The Airline will consider PriceLine notified of any
changes when WorldSpan has completed loading the ATPCO file. The following chart
