Reservation Information Systems
The airline reservations system was one of the earliest changes to improve efficiency in the airline industry. Airline Reservation System finally evolved into the computer reservations system (CRS). Airline Reservations System (ARS) is a computerized system used to store and retrieve data and conduct transactions associated with air travel. The systems were originally designed and operated by airlines but were later extended for the use of travel agencies.
Major airline reservation system operations that book and sell tickets for multiple airlines are known as Global Distribution Systems (GDS). Airlines have divested most of their direct holdings to devoted GDS corporations, who make their programs accessible to shoppers by means of Web gateways. Modern Global Distribution Systems typically allow users to book hotel rooms and rental cars as well as airline tickets.
Global Distribution Systems(GDS) is a worldwide computerized reservation network used as a single point of access for reserving airline seats, hotel rooms, rental cars, and other travel related items by travel agents, online reservation sites, and large corporations. The premier global distribution systems are Amadeus, Galileo, Sabre, and Worldspan. They are owned and operated as joint ventures by major airlines, car rental companies, and hotel groups.
