SABR

Sabre Corporation

A global travel technology firm, Sabre runs one of the world's largest booking networks that lets travel agents, corporate travel departments, and online agencies search and reserve flights, hotels, car rentals, and more in one place, while also selling software airlines use to manage reservations and retailing. Its name began in the 1950s, when American Airlines and IBM built an automated reservation system dubbed "Semi-Automated Business Research Environment," later shortened to Sabre. Fun fact: the name and design were inspired by SAGE, a Cold War air-defense computer system.
