What is GDS?

Global Distribution System

GDS is an advanced computerized network system. It facilitates transactions between various travel industry service providers such as airlines, hotels, and car rental companies. GDS receives real-time inventory from these providers and distributes it to consumers. Travel agencies are the primary users of this system.

GDS are linked by travel agencies to facilitate the direct online sale of tickets through their B2B, B2C, B2B2B, and B2B2C portal interfaces. The major GDS providers, including Sabre, Galileo, Amadeus, and World span, offer an all-encompassing e-commerce and reservation platform to OTAs globally. These systems effortlessly connect services, rates, and reservations while consolidating products and services from all three travel sectors- airlines, hotels, and car rentals.

Amadeus enables travel agencies to gather customer requirements and provides clients with direct access to the necessary services.
