A Global Distribution System (GDS) is a computerized network that connects travel agencies, airlines, hotels, and car rental companies, enabling seamless booking of travel services. Major GDS providers, such as Amadeus, Sabre, and Travelport, allow travel agencies to access real-time flight availability, fare comparisons, and seat inventory across multiple airlines, ensuring efficient and competitive travel planning.

For corporate travel management, a GDS is essential in securing negotiated rates, tracking travel expenses, and maintaining policy compliance. Unlike public online booking platforms, GDS systems provide travel agents with direct access to airline and hotel inventory, offering more flexible options for complex itineraries. Businesses benefit from cost savings, detailed reporting, and enhanced traveler support when bookings are managed through a GDS-powered travel agency.
