Main Page | See live article | Alphabetical index 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.
