- Airline Reservations System
The Airline Reservations System (ARS) was one of the earliest changes to improve efficiency. ARS eventually evolved into the
Computer Reservations System(CRS), and then into Global Distribution System (GDS).
The history of airline reservations systems began in the late 1950s when
American Airlinesrequired a system that would allow real-time access to flight details in all of its offices, and the integration and automation of its booking and ticketing processes. As a result, Sabre (Semi-Automated Business Research Environment) was developed and launched in 1964. Sabre's breakthrough was its ability to keep inventory correct in real time, accessible to agents around the world. Prior to this, manual systems required centralized reservation centers, groups of people in a room with the physical cards that represented inventory, in this case, seats on airplanes.
deregulationof the airline industry, in the Airline Deregulation Act, meant that airlines, which had previously operated under government-set fares ensuring airlines at least broke even, now needed to improve efficiency to compete in a free market. In this deregulated environment the ARS and its descendants became vital to the travel industry.
