Understanding NDC and GDS: What tour operators need to know
If you’ve been in the travel industry for a while, you know that airline content isn’t all the same. Most tour operators rely on a Global Distribution System (GDS), like Amadeus, Sabre, or Travelport, for flight inventory. GDS networks have been around for decades, aggregating schedules, fares, and availability from multiple airlines in one place.
But there’s a newer player in the market: New Distribution Capability (NDC). Developed by IATA, NDC allows airlines to offer richer content – think bundled fares, ancillaries, and personalised offers – that often aren’t available through a GDS.
The challenge? Each system has unique strengths. Limiting your operations to just one could mean missing fares, upsell opportunities, or ancillary services that could boost revenue.
Why having both NDC and GDS matters
Access the full range of fares
Some airlines distribute certain fares exclusively via NDC. Others are only available through GDS. By integrating both, you ensure your customers see the widest possible range of options, keeping your offerings competitive.
Maximise revenue potential
NDC content often includes add-ons like seat selection, baggage, or bundled packages. Combined with GDS inventory, you can increase upsells while still offering volume through traditional fares.
Reduce operational complexity
Historically, integrating multiple sources meant handling separate APIs, workflows, and reconciliations. A modern flight API that aggregates both NDC and GDS, like InfiniteAPI, simplifies this process, saving time and resources while providing a single point of access.
How to avoid Distribution Technology Charges
Many airlines charge a Distribution Technology Charge (DTC) for bookings made through indirect channels like GDS. These fees can cut into your margins if not carefully managed.
By accessing NDC content directly and combining it with GDS through an airfare API, tour operators can:
- Minimise reliance on GDS for certain routes
- Avoid unnecessary fees
- Offer more competitive pricing to customers
Choosing the right flight API
When evaluating a flight API, look for features that support both NDC and GDS integration, including:
- Real-time availability and fares – Accurate information builds trust and reduces abandoned searches.
- Ancillary content access – Upsell options like baggage or seat selection can increase revenue per booking.
- Seamless booking flow – Simplifies operations and improves customer experience.
- Single integration point – Saves time and reduces technical complexity.
Tour operators who adopt a solution like InfiniteAPI can aggregate both NDC and GDS content in one place, giving customers instant, accurate, and complete flight options.
The bottom line
The modern travel market demands flexibility, efficiency, and choice. Accessing both NDC and GDS content ensures your customers get the best fares, widest inventory, and seamless booking experience.
A single, well-designed API lets tour operators save time, avoid unnecessary fees, and deliver instant results – giving you a competitive edge while improving conversions.
