On July 22, 2009, the Audit Committee of the Board of Directors of UAL Corporation (“UAL”) approved on behalf of UAL and its subsidiary, United Air Lines, Inc. (“United”), the dismissal of their independent registered public accounting firm, Deloitte & Touche LLP (“Deloitte”), and the engagement of Ernst & Young LLP (“EY”) to serve as their new independent registered public accounting firm for 2010. The Board of Directors of UAL ratified the dismissal of Deloitte and the engagement of EY by the Audit Committee on July 23, 2009. The dismissal of Deloitte will become effective following the conclusion of Deloitte’s 2009 fiscal year audit for UAL. The engagement of EY as UAL’s new independent registered public accounting firm will become effective for the 2010 fiscal year.

Deloitte’s reports on UAL’s and United’s consolidated financial statements for each of the years ended December 31, 2008 and December 31, 2007 did not contain an adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.

During the years ended December 31, 2008 and December 31, 2007 and the interim period between December 31, 2008 and the date of this Form 8-K, there were no disagreements between UAL or United and Deloitte on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure which, if not resolved to Deloitte’s satisfaction, would have caused Deloitte to make reference to the subject matter of the disagreement in connection with its report for such years; and there were no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

UAL has provided Deloitte with a copy of the foregoing disclosures. A copy of Deloitte’s letter, dated July 28, 2009, stating its agreement with the above statements is attached as Exhibit 16.1.

During the years ended December 31, 2008 and December 31, 2007 and through the date of this Form 8-K, neither UAL nor United nor anyone acting on their behalf consulted EY with respect to the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on UAL’s or United’s consolidated financial statements, or any other matters or reportable events listed in Items 304(a)(1)(iv) and (v) of Regulation S-K.
