I, John W. Creighton, state and attest that:

(1) To the best of my knowledge, based upon a review of the covered reports of UAL Corporation, and, except as corrected or supplemented in a subsequent covered report:

--  no covered report omitted to state a material fact necessary to make the statements in the covered report, in light of the circumstances under which they were made, not misleading as of the end of the period covered by such report (or in the case of a report on Form 8-K or definitive proxy materials, as of the date on which it was filed).

(2) I have reviewed the contents of this statement with the UAL Corporation Audit Committee.

(3) In this statement under oath, each of the following, if filed on or before the date of this statement, is a "covered report":
 

--  Form 10-K for the year ended December 31, 2001 of UAL Corporation;
