Travel GDS Software is a network that enables travel agencies and other travel-related businesses to access real-time information about travel products such as flights, hotels, and car rentals. Travel GDS software works by connecting to a central database that contains information from various travel service providers. When a user searches for travel options, the GDS software retrieves and displays relevant information from the database, allowing the user to compare and book travel services. This system streamlines the booking process and provides travel professionals and customers with comprehensive information.
