NDC
NDC Airline API Guide for Modern OTAs
How New Distribution Capability changes air retailing and airline offers
By Project OTA | 30 Jun, 2026 | 6 min read
NDC can improve airline retailing with richer offers and ancillaries, but OTAs need strong offer, order and servicing workflows.
What NDC changes
NDC is designed to help airlines distribute richer offers, branded fares, seats, baggage and ancillaries through modern APIs. For OTAs, it can provide content that may not be available in the same form through traditional channels.
The shift is from simple fare display toward offer and order management. That means the platform must understand airline-specific rules, order identifiers and servicing capabilities.
NDC is not a full replacement for GDS
Many agencies still need GDS content for coverage, ticketing workflows and corporate servicing. NDC is often added beside GDS and LCC APIs rather than replacing them immediately.
A practical OTA strategy is to normalize NDC offers into the same shopping experience while preserving airline-specific data for booking and order management.
Implementation risks
NDC capabilities vary by airline and technology provider. Some flows support easy servicing, while others may require manual airline handling. Agencies should test booking, payment, seat selection, refund and exchange scenarios before launch.
The admin panel should show whether an order came from GDS, NDC, LCC or aggregator content so support teams know how to handle it.
Frequently Asked Questions
Why do OTAs use NDC APIs?
OTAs use NDC APIs to access richer airline offers, ancillaries and retailing content that can improve choice and revenue opportunities.
Is NDC easier than GDS integration?
Not always. NDC can be technically modern, but airline-specific variations and servicing rules can make implementation complex.
Key Takeaways
- NDC focuses on airline offers, ancillaries and order-based retailing.
- NDC content can complement GDS, LCC and consolidator supply.
- Servicing workflows must be checked carefully by airline and aggregator.
Project OTA helps agencies add NDC content without losing control of search, checkout and post-booking support.
