FORT WORTH, Texas -- AMR Corp., parent company of American Airlines Inc., today announced that it would spin off its 83 percent interest in Sabre Holdings Corp. (Sabre) by distributing its 107 million shares of Sabre common stock to AMR shareholders. The transaction is subject to receipt of a favorable ruling from the U.S. Internal Revenue Service that the spin-off will be tax- free to AMR and its shareholders for U.S. federal income tax purposes. In a related announcement today, Sabre announced William J. Hannigan, age 40, as its new President and CEO, effective immediately. Hannigan joins Sabre from Southwestern Bell, where he served as President of SBC Global Markets. The spin-off is expected to be completed in the first quarter of 2000, and AMR shareholders will receive approximately 0.7 shares of Sabre stock for each share of AMR stock owned. In announcing the transaction, AMR Chairman and Chief Executive Officer Donald J. Carty said, "The spin-off of Sabre into a fully independent technology company will mean a clear and refined definition of the respective goals of AMR and Sabre. For AMR, that means a complete focus on American Airlines and American Eagle, allowing management to devote the time and resources to maintain and enhance its global airline leadership. For Sabre, this new independence will allow it to fully utilize its position as the global leader in travel --more--

6 and transportation information technology. The spin-off will also allow Sabre - and Sabre's subsidiary, Travelocity.com, the leading online travel expert - to capitalize on numerous opportunities in the rapidly evolving technology sector." Carty also noted that AMR's stock price has often not reflected the full value of both American Airlines and Sabre. "By having two completely separate companies valued in the market, both AMR and Sabre should benefit from clearer market comparisons with their peers," he said. "This should result in a stock price for both companies that more appropriately reflects their full value and potential." Commenting on his new position, Hannigan said, "Sabre has put together an outstanding management team that is well respected by customers, investors and employees. Moreover, Sabre has developed the corporate infrastructure and expertise to support world-class clients, not to mention its Internet leadership with Travelocity.com. All of this firmly establishes Sabre's position for success in the marketplace, and I look forward to this exciting new challenge." The Sabre spin-off culminates a process begun in 1996 when AMR reorganized Sabre - previously part of American Airlines - into a separate subsidiary and made an initial public offering of approximately 18 percent of Sabre's ownership to public shareholders. At that time, American and Sabre reached a comprehensive agreement for Sabre to provide the airline with substantially all of its information technology needs, including reservations, flight operations and other real-time services. Following the spin-off, Sabre will continue to provide such services and, in connection with the transaction, American and Sabre have agreed to extend by two years, to 2008, the agreements to provide real-time services. Prior to the spin-off, Sabre will pay a special, one-time $675 million cash dividend, or approximately $5.21 per share, to its shareholders, including AMR. The proceeds of the dividend will be used by AMR to enhance its already strong balance sheet. Over time, it will also enable AMR to pursue options to invest in its core airline business. ### Current AMR Corp. press releases can be accessed via the Internet.
