GDS (Global Distribution System)
Definition
Older distribution networks (Amadeus, Sabre, Travelport) that connect hotels to travel agents and corporate booking tools. Pre-dates OTAs; remains important for corporate and travel-agent business.
What it tells you
GDS bookings typically come from corporate accounts, travel-agent reservations, and managed-travel programs. The volume is smaller than OTA but the average booking is often higher value (longer stays, higher ADR).
How to track it
GDS is captured as a channel in PMS. Most BI tools surface GDS performance separately. Channel manager configurations often include GDS as a connected channel.
Where it fits
GDS matters more for properties with significant corporate or travel-agent business. For pure-leisure independent hotels, GDS is a small fraction of mix; for business-travel-heavy city hotels, it’s meaningful.
