Sabre Airline Reservations System
Sabre was the world's first online airline reservations system. Developed through the joint efforts of
IBM and
American Airlines, it first went online in the fall of 1962, running on an
IBM 7090 computer. After going through a series of system upgrades, including a relocation from Westchester County, NY to Tulsa, OK, the system remains operational today (2003) and was the prototype for virtually every mainframe-based online system that followed.
