GDS is an interface between airline and the travel agent. it helps travel agents to create airline bookings, price the passenger’s itinerary and issue tickets etc. However, GDS facilitates in Hotels and car bookings too but the travel agents prefer to go through the direct venders. GDS is a B2B booking tool for the Travel Agent where the airlines directly update their inventory and since it is updated by the airline itself the inventory is real time updated. The booking that are created on the GDS systems are real time and are updated with the PNR numbers the moment they are created.
It goes without saying that knowledge of GDS is important as Air bookings are the key elements of any itinerary .Creating a booking on the GDS gives full control over the booking, assess last minute changes and helps agent to explore cheaper options too.
Amadeus and Galileo are the most prominent GDS software in India that gives easy access to the airline inventory and full authority to create PNRs and issue tickets, processing refunds and reissues.
