Which of the following is a major global distribution system?

The correct answer, Galileo, is indeed a major global distribution system (GDS). Galileo is widely recognized for providing travel agents and companies with access to a vast range of travel content, including airline schedules, availability, and pricing. As part of the travel technology landscape, it plays a crucial role in facilitating bookings and managing reservations across various travel sectors.

Galileo operates by connecting travel agents with airlines, hotels, car rental services, and other travel-related services in a centralized database, making it easier for agents to provide customers with a variety of travel options and efficient booking processes. Its importance is underscored by the extensive network it maintains, allowing for streamlined operations and enhancing the overall travel experience for both agents and consumers.

In contrast, while Amadeus, Sabre, and Travelport are also significant global distribution systems, the context of the question was likely focused on a comparison of these GDS options. Each GDS has its unique capabilities and markets it serves; however, Galileo specifically stands out in some regions for its integration and user-friendly features favored by many travel professionals.
