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 IATA, OTA and SITA.
Galileo International was founded in 1971 as Chicago-based United Airlines introduced the Apollo® computer reservation system (CRS), for use in their own offices to automate seat reservation, booking and tracking. Five years later, United created the Apollo Travel Services (ATS) division, and the Apollo CRS was marketed to travel agencies in North America and Japan.
In 1986 Apollo Travel Services, was renamed Covia, and became an independent affiliate of United Airlines. In response to the growing need for CRS automation in Europe, The Galileo Company Ltd was incorporated by shareholders British Airways, Swissair, KLM Royal Dutch Airlines, Alitalia and Covia. In the U.S., United Airlines sold 50 percent of Covia to USAir, British Airways, Swissair, KLM Royal Dutch Airlines and Alitalia, creating the Covia Partnership. Three years later, Air Canada, Austrian Airlines, Aer Lingus, TAP Air Portugal, Sabena and Olympic Airways became Covia's final eleven airline owners.
In 1997, Galileo International became a publicly traded company, listed on the New York and Chicago Stock Exchanges. Four years later, in October 2001, Galileo became a subsidiary of Cendant Corporation (NYSE: CD), forming the cornerstone of Cendant's Travel Distribution Division.
