CONFIRM was an ambitious IT project supposed to create a single computer reservations system/global distribution system used by airline, rental car, and hotel companies.
In 1988 the four large corporations made contracts to complete the system by June 1992 project at a cost of $55 million.
In April 1992, just three months before the system was intended to go live, Confirm failed tests at Los Angeles-based Hilton.
In September 1992, AMR (American Airlines) sued Marriott, Hilton and Budget, alleging they caused CONFIRM's failure by withholding funds, making poor staffing assignment and withdrawing prematurely.
[1] In January 1994, American Airlines reached out-of court settlements with all of its partners for undisclosed amounts.
