New Distribution Capability (NDC) is a data exchange format based on Offer and Order management processes for airlines to create and distribute relevant offers to the customer regardless of the distribution channel. ​​​​



NDC (New Distribution Capability) is a travel industry-supported program (NDC Program) launched by IATA for the development and market adoption of a new, XML-based data transmission standard (NDC Standard). The NDC Standard enhances the capability of communications between airlines and travel agents and is open to any third party, intermediary, IT provider or non-IATA member, to implement and use.


NDC enables the travel industry to transform the way air products are retailed to corporations, leisure and business travelers, by addressing the industry’s current distribution limitations: product differentiation and time-to-market, access to full and rich air content and finally, transparent shopping experience.

Who will benefit and how?

Available on a voluntary and open basis, NDC benefits different industry players across the airline distribution value chain as follows:

  • Full service and low-cost airlines > Differentiate their Products and Services
  • Travel Sellers > Access Full and Rich Air Content of the Airlines
  • Customers > Benefit from a Transparent Shopping Experience

The current NDC and ONE Order certifications and Supporting NDC recognition will move into the Airline Retailing Maturity (ARM) index with a broader scope to cover airline retailing using offers and orders based on the IATA Enhanced and Simplified Distribution (EASD) standards. We have created an Airline Retailing Maturity index website with videos, resources and documentation to help transition into the new certification model.

The ARM index will be publicly launched in October 2021 at the Digital, Data & Retailing (DDR) Symposium. The current registries will continue to exist in parallel until October 2022, however beginning in October 2021 all new certifications and renewals will be on the new ARM index.

Are you NDC certified?

IATA provides the only official industry certification program for NDC.

The certification process examines the capabilities of airlines, agents and aggregators to receive and send NDC messages, testing specific NDC solutions.

NDC Certification covers:

  • Airlines, Sellers and Aggregators – Any airline that deploys an NDC API or any seller or aggregator that consumes these APIs; and
  • IT Providers – Any vendor that offers NDC products and services for airlines and distributors can become NDC capable.

Access now the NDC Certification Registry to see who are the NDC certified /capable actors.

The Standard

The NDC Messages are governed by the Shop-Order Standards Board under the Passenger Standards Conference and managed by three specialised Industry Groups; the Offer, Order and Customer Payment Groups. These Groups, ensure the standard is maintained and improved each release. 

If you are an airline or strategic partner and would like to join the conversations and help set the standard, please contact for more information.
