ITEM 7.01. REGULATION FD DISCLOSURE.

Following are certain preliminary system statistics and traffic results for Atlas Air Worldwide Holdings, Inc., a Delaware corporation (the “Company”), for each of the months January 2004 through July 2004, year-to-date for the period ended July 31, 2004, and for the corresponding periods during the prior year (the “Operating Statistics”). For the period of January 2004 through July 2004, total block hour activity for the Company declined 3.5% versus the same period in 2003. Over the same period the average number of aircraft operated by the Company declined by 16.0%. Block hours operated in the ACMI segment increased 19.8% year over year, while Commercial Charter hours declined 43.6%, primarily due to a reallocation of available aircraft to other business segments, and Military Charter hours declined 45.7%. Capacity in the Scheduled Service business (as measured by available ton miles “ATM’s”) increased 16.4% year over year, and traffic (as measured by revenue ton miles “RTM’s”) increased 20.5% year over year, resulting in an increased load factor of 60.8% in 2004 over the 57.7% load factor in 2003.

The Operating Statistics do not constitute financial statements, were not prepared in accordance with generally accepted accounting principles, and do not contain all of the disclosures required by generally accepted accounting principles or by the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or any other prescribed form or format. The Company cautions readers not to place undue reliance upon the information contained in the Operating Statistics. The Operating Statistics, which have not been audited, may not be indicative of the Company’s financial statements in reports that would be required to be filed pursuant to the Exchange Act.

As previously reported, on July 27, 2004, the Company and its affiliated debtor subsidiaries completed their financial restructuring and emerged from Chapter 11 bankruptcy protection as their Joint Plan of Reorganization became effective. On January 30, 2004, the Company and such affiliated debtor subsidiaries had each filed a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the Southern District of Florida.

On July 23, 2004 and July 29, 2004, under cover of Form 8-K and Form 8-K/A, respectively, the Company previously filed its audited consolidated balance sheets as of December 31, 2003 and 2002 and the related consolidated statements of operations, stockholders’ equity (deficit), and cash flows for each of the two years in the period ended December 31, 2003, together with the related report of Ernst & Young LLP. On December 12, 2003, under cover of Form 8-K, the Company filed its audited consolidated balance sheet as of December 31, 2002 and the related consolidated statement of operations, stockholders’ equity and cash flows for the year then ended, together with the related report of Ernst & Young LLP. The Company expects to file a report or reports for certain completed fiscal periods as soon as reasonably practicable; until the Company files such report or reports, however, the Company expects to provide supplemental operational information through the release of operating statistics and supplemental data, as applicable, under cover of Form 8-K.

As previously reported, Polar Air Cargo, Inc. (“Polar”), one of the Company’s subsidiaries, was tentatively selected by the U.S. Department of Transportation (“DOT”) as the next U.S. carrier to be designated under the recently

signed aviation agreement with China. The DOT’s decision tentatively grants Polar the right to conduct six weekly flights to mainland China this year, expanding to nine frequencies in 2005.

The Operating Statistics and the related discussion contained in this Item 7.01 are being furnished in accordance with Rule 101(e)(1) under Regulation FD and shall not be deemed to be filed.

The Operating Statistics and this Report on Form 8-K may include forward-looking statements, including, for example, statements about management expectations, strategic objectives, business prospects, anticipated expense savings and financial results, anticipated results of legal proceedings, and other similar matters. These forward-looking statements are not statements of historical facts and represent only the Company’s beliefs regarding future events, which are inherently uncertain. There are a variety of factors, many of which are beyond the Company’s control, which affect its operations, performance, business strategy and results and could cause its actual results and experience to differ materially from the expectations and objectives expressed in any forward-looking statement. These factors include, but are not limited to, the following: the ability of the Company to operate pursuant to the terms of its financing facilities; 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 ability of the Company to fund and execute its business plan; the ability of the Company to attract, motivate and/or retain key executives and associates; the ability of the Company to attract and retain customers; the ability of the Company to continue as a going concern; demand for cargo services in the markets in which the Company operates; economic conditions; the effects of any hostilities or act of war (in the Middle East or elsewhere) or any terrorist attack; labor costs; financing costs; the cost and availability of war risk insurance; aviation fuel costs; security-related costs; competitive pressures on pricing (especially from lower-cost competitors); weather conditions; government legislation and regulation; consumer perceptions of the Company’s products; pending and future litigation; the market acceptance of the Company’s new common stock; and other risks and uncertainties set forth from time to time in the Company’s reports to the United States Securities and Exchange Commission. Other factors and assumptions not identified above are also involved in the preparation of forward-looking statements, and the failure of such other factors and assumptions to be realized may also cause actual results to differ materially from those discussed. The Company assumes no obligation to update such estimates to reflect actual results, changes in assumptions or changes in other factors affecting such estimates other than as required by law.
