Global Distribution Systems (GDS) are computerized networks that facilitate the distribution of travel-related services, such as airline tickets, hotel bookings, and car rentals. They connect travel agents, online travel agencies, and other service providers to a wide range of travel options, allowing for real-time availability and pricing. GDS platforms, like Amadeus, Sabre, and Travelport, serve as intermediaries between suppliers and consumers. They streamline the booking process, making it easier for travel professionals to access and compare various travel products, ultimately enhancing the efficiency of the travel industry.
