Airline Distribution
GDS (Global Distribution System)
A global network enabling real-time transactions between travel agents and suppliers — airlines, hotels, car rental.
In simple terms
A GDS is a giant real-time marketplace where agents search and book travel inventory instantly.
Real-world example
Amadeus, Sabre, and Travelport are the three major GDSs.
Why it matters
GDSs remain the backbone of traditional travel agent distribution, even as NDC grows in parallel.
Common mistake
Assuming GDS technology is obsolete — it still processes the majority of agency-booked airline tickets globally.
Interview question
Explain the GDS's role in airline distribution and where NDC is changing that.
