Together, Let's Build Airline Retailing

NDC (New Distribution Capability) will enable the travel industry to transform the way air products are retailed to corporations

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. The NDC Standard is open to any third party, intermediary, IT provider or non-IATA member, to implement and use.

The NDC Standard 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
  • Transparent shopping experience

Backporting Guidelines

How to leverage standards enhancements in older versions?

As new releases of the standards bring in new features and functionality, some of these may be required for implementers using previous versions of the standards. This section is intended to describe commonly agreed details on how to "backport" important features.

An example of this is the impending PSD2 regulation coming into effect in September 2019. While the 19.2 version of the standards (due for publishing in Aug 2019) will support the new 3D Secure v2 features, implementers of earlier versions (notably the currently popular 17.2) need help to integrate this essential feature in their current solutions and, if possible, in a way that is consistent across other 17.2 implementations also requiring to leverage this new feature.
