Galileo GDS

Galileo is a computer reservations system (CRS) owned by Travelport. As of 2002, it had a 26.4% share of worldwide CRS airline bookings.

In addition to airline reservations, the Galileo CRS is also used to book train travel, cruises, car rental, and hotel rooms.

The Galileo system was moved from Denver, Colorado, to the Worldspan datacenter in Atlanta, Georgia, on September 28, 2008, following the 2007 merger of Travelport and Worldspan (although they now share the same datacenter, they continue to be run as separate systems).

Galileo is subject to the Capps II and its successor Secure Flight program for the selection of passengers with a risk profile.

Galileo is a member of the International Air Transport Association, of the OpenTravel Alliance and of SITA.

Galileo traces its roots back to 1971 when United Airlines created its first computerized central reservation system under the name Apollo. During the 1980s and early 1990s, a significant proportion of airline tickets were sold by travel agents. Flights by the airline owning the reservation system had preferential display on the computer screen. Due to the high market penetration of the Sabre and Apollo systems, owned by American Airlines and United Airlines, respectively, Worldspan and Galileo were created by other airline groups in an attempt to gain market share in the computer reservation system market and, by inference, the commercial airline market. Galileo was formed in 1987 by nine European carriers -- British Airways, KLM Royal Dutch Airlines, Alitalia, Swissair, Austrian Airlines, Olympic, Sabena, Air Portugal and Aer Lingus.
