The four Global Distribution Systems (GDS) – Amadeus, Galileo, Sabre and Worldspan – have been referred to as the backbone of the modern travel distribution system (Bear Stearns, 2000 – Internet Travel: Point, Click, Trip: An Introduction to the Online Travel Industry, London: 1-99). They have processed more than 1 billion air bookings each, and another 250 million for hotels, cruises and other non-air content, generating over US$6 billion in revenues. Sabre and Amadeus own the largest civilian data-processing centres in the US and Europe respectively. The volume of global transactions through the GDS has risen 4% year-on-year to 343 million. Worldwide, the GDS reaches some 230,000 points of sale.
