A Travel GDS or Global Distribution System (GDS) can connect services, pricing, and bookings across all three travel sectors, particularly reservations in airlines, hotels, car rentals, and activities. Traditionally, travel agencies relied on GDS for services, products, and rates to provide travel-related services to end-users. A GDS is capable of connecting services, fees, and reservations. It incorporates products and services from all three travel businesses, such as airline and hotel booking and car rentals. For air ticketing, travel GDS remains the dominant distribution channel. https://www.travelopro.com/travel-gds-global-distribution-system.php
