Exhibits

Exhibit Description

99 Monthly Operating Report of ATA Holdings Corp. for the period May 1, 2005 through May 31, 2005

Certain of the information contained in this report should be considered “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 that reflect the Company’s current views with respect to certain current and future events and financial performance. Such forward-looking statements are and will be, as the case may be, subject to many risks, uncertainties and factors relating to the Company’s operations and business environments which may cause the actual results of the Company to be materially different from any future results expressed or implied in such forward-looking statements. Factors that could cause actual results to differ materially from these forward-looking statements include, but are not limited to, the following: the ability of the Company to continue as a going concern; the ability of the Company to develop, prosecute, confirm and consummate one or more plans of reorganization with respect to the Chapter 11 case; risks associated with third parties seeking and obtaining bankruptcy court approval to terminate or shorten the exclusivity period for the Company to propose and confirm one or more plans of reorganization, for the appointment of a Chapter 11 trustee or to convert the case to a Chapter 7 case; the ability of the Company to obtain and maintain normal terms with vendors and service providers; the Company’s ability to maintain contracts that are critical to its operations; the potential adverse impact of the Chapter 11 case on the Company’s liquidity or results of operations; the ability of the Company to fund and execute its business plan and to attract, motivate and/or retain key executives and associates; the ability of the Company to attract and retain customers; demand for transportation in the markets in which the companies operate; economic conditions; the effects of any hostilities or act of war; labor costs; aviation fuel costs; competitive pressures on pricing (particularly from lower-cost competitors); weather conditions; government legislation and regulation; and other risks and uncertainties set forth from time to time in the Company’s reports to the United States Securities and Exchange Commission.

Similarly, these and other factors, including the terms of any reorganization plan ultimately confirmed, can affect the value of the Company’s various pre-petition liabilities, common stock and/or other equity securities. No assurance can be given as to what values, if any, will be ascribed in the bankruptcy proceedings to each of these constituencies, and it is possible that the Company will be restructured in a manner that will substantially reduce or eliminate any remaining value. Accordingly, the Company urges that the appropriate caution be exercised with respect to existing and future investments in any of these liabilities and/or securities.
