The History of Global Distribution Systems (GDS)
The history of Global Distribution Systems (GDS) traces back to the mid-20th century, when airlines began seeking more efficient ways to manage reservations as air travel boomed.
Initially, bookings were handled manually with paper cards, but by the early 1960s, airlines like American Airlines, in partnership with IBM, developed computerized reservations systems such as SABRE, which could process thousands of bookings per hour and changed the industry.
The 1980s and 1990s saw the formal emergence and rapid expansion of GDSs, with major systems like SABRE, Amadeus (founded by Air France, Lufthansa, Iberia, and SAS in 1987), and Galileo (established by British Airways, KLM, and others) dominating the market.
These top GDS platforms evolved beyond flights to include hotels, car rentals, and other travel services, becoming central to global travel distribution. The rise of the internet in the 1990s further transformed GDSs, enabling online bookings and greater consumer access.
Today, GDSs remain vital to the travel industry, connecting service providers with agents and travelers globally, even as new technologies and distribution models continue to emerge.
