Computer Reservation System [CRS]

Updated: 2017-12-20.

A computer reservation system, or CRS, is a system for making travel reservations. In the airline industry, a CRS handles the reserving and booking of seats on commercial flights electronically, as well as storage and retrieval of itineraries.

Other segments of the travel industry, such as accommodations and other forms of transportation, utilize their own forms of a CRS.

Several airlines own and market such systems, which are used by travel agents. A few include: Sabre (produced by American Airlines), Amadeus, and Worldspan.
