ITEM 1         SECURITY AND ISSUER

               This Amendment No. 9 to Schedule 13D relating to the common stock
of priceline.com Incorporated, a Delaware corporation ("priceline"), is being
filed on behalf of Delta Air Lines, Inc., a Delaware corporation ("Delta"), to
amend the Schedule 13D which was originally filed with the Securities and
Exchange Commission on October 20, 2000 and which was amended on November 14,
2000, February 6, 2001, May 24, 2001, June 8, 2001, June 13, 2001, June 29,
2001, August 8, 2001 and January 31, 2001 (as amended, the "Schedule 13D").
Unless otherwise indicated, all capitalized terms used herein but not defined
herein shall have the meanings set forth in the Schedule 13D.


ITEM 5         INTEREST IN SECURITIES OF PRICELINE

               Item 5 is hereby amended by adding the following information:

               On January 31, 2002 and February 1, 2002, Delta sold an aggregate
of 1,728,571 shares of priceline common stock in transactions on the Nasdaq
National Market for an aggregate sales price of approximately $10,852,008.03
(the "Open Market Sales"). The Open Market Sales are summarized as follows: (a)
Delta sold 850,000 shares on January 31, 2002 at an average price per share of
$6.12 and (b) Delta sold 878,571 shares on February 1, 2002 at an average price
per share of $6.43.

               Immediately after the consummation of the Open Market Sales,
Delta beneficially owned 11,801,153 shares of priceline common stock. The shares
beneficially owned by Delta after consummation of the Open Market Sales
represented approximately 4.95% (assuming the exercise of Delta's right to
purchase all 4,675,000 shares of priceline common stock pursuant to the Amended
1999 Warrant and the exercise of Delta's right to purchase the remaining
4,537,199 shares of priceline common stock pursuant to the 2001 Warrant) of the
shares of priceline common stock outstanding on November 12, 2001, as set forth
in priceline's Quarterly Report on Form 10-Q for the quarter ended September 30,
2001. The number of shares of priceline common stock beneficially owned by Delta
and the number of shares of priceline common stock assumed to be outstanding
have been adjusted pursuant to Rule 13d-1(j) and Rule 13d-3(d)(1).

               As a result of the Open Market Sales, Delta ceased to be the
beneficial owner of more than 5% of priceline's common stock on February 1,
2002.
