the Securities and Exchange Commission (the "Commission") on October 6, 2004,
by Robertson Acquisition Corporation, a Delaware corporation (the "Purchaser")
and an indirect wholly owned subsidiary of Cendant Corporation, a Delaware

thereon, upon the terms and subject to the conditions set forth in the Offer
to Purchase dated October 6, 2004 (the "Offer to Purchase"), and in the
related Letter of Transmittal (the "Letter of Transmittal"), copies of which
are filed as Exhibit (a)(1)(A) and Exhibit (a)(1)(B) to the Statement,
respectively. Capitalized terms used and not otherwise defined in this
Amendment shall have the meanings assigned to such terms in the Offer to
Purchase or in the Statement.

Item 4.  Terms of the Transaction.

         Item 4 of the Statement is hereby amended and supplemented as
follows:

         The Offer to Purchase is hereby amended by restating the last
sentence of the penultimate paragraph of Section 1 of the Offer to Purchase
entitled "Terms of the Offers" to read as follows:

         "In the event the Purchaser elects to include a Subsequent Offering
Period, it will notify stockholders of Orbitz by making a public announcement,
consistent with the requirements of the SEC, not later than 9:00 a.m., New
York City time, on the first business day after the Expiration Date."

         The Offer to Purchase is hereby amended by restating the first two
sentences of the ultimate paragraph of Section 14 of the Offer to Purchase
entitled "Certain Conditions of the Offers" to read as follows:

         "The foregoing conditions are for the sole benefit of Cendant and the
Purchaser, may be asserted by Cendant or the Purchaser regardless of the
circumstances giving rise to such condition, and may be waived by Cendant or
the Purchaser in whole or in part from time to time at any time prior to the
Expiration Date or, with respect to conditions relating to regulatory
approvals, prior to the payment for any Shares pursuant to the Offers, in each
case subject to the terms of the Merger Agreement. The failure by Cendant or
the Purchaser at any time to exercise any of the foregoing rights will not be
deemed a waiver of any such right and each such right will be deemed an
ongoing right that may be exercised from time to time."

Item 11.  Additional Information.

         Item 11 of the Statement is hereby amended and supplemented as
follows:

         The Offer to Purchase is hereby amended by restating the paragraph
captioned "Bankruptcy Court Approval" of Section 13 of the Offer to Purchase
entitled "The Merger Agreement, Stockholder Agreements and Other Agreements"
to read as follows:

         "Bankruptcy Court Approval. Pursuant to the Merger Agreement, Orbitz,
the Purchaser and Cendant will use their commercial best efforts to
facilitate, and cooperate with the applicable bankruptcy courts to obtain, any
approvals required by such courts in connection with the transactions
contemplated by the Merger Agreement. Issuance of the United Bankruptcy Court
Approval is a condition to the Offers, and is required in order for United to
take certain actions in connection with the Offers and the Merger, as
described in the subsection below captioned "Stockholder Agreements". See
Section 14--"Certain Conditions of the Offers" and Section 15--"Certain Legal
Matters" for a description of the United Bankruptcy Court Approval."

         The Offer to Purchase is hereby amended by restating the penultimate
paragraph of Section 15 of the Offer to Purchase entitled "Certain Legal
Matters" to read as follows:

         "United Bankruptcy Court Approval. On October 1, 2004, United and its

Court seeking the United Bankruptcy Court Approval and other related relief.
On October 15, 2004, the Bankruptcy Court issued an order granting the relief
