Global Distribution System (GDS)
Home / Courses / Global Distribution System (GDS)
The Global Distribution System (GDS) is a primary reservation tool for travel agents. GDS is a network/platform that enables travel agencies and their clients to access travel data, shop for and compare reservations options and book travel. There are three important GDS systems: Travel port (Galileo, Apollo, World span), Amadeus and SABRE. Through such commerce platforms, agents can access scheduling and inventory of hotels, airlines, car rentals, and (some) railway and bus reservations – in real time. GDS links all those services across the three primary travel reservation sectors (airline, hotel, and ground transportation, i.e., car rentals), and activities.
