NDC Schema Description

The NDC (EDIST) PADIS 17.1 Release Schemas introduce the newly restructured NDC Offers and Orders – leveraging the feedback we received from early deployments and pilots. The NDC Schemas fulfill the business requirements for Shopping, including support for Interline Ancillary Shopping, Order Management (Booking and Servicing), Payment and Ticketing, Interline interactions and messages to fulfill Airline Profile requirements. The schemas package includes the messages below, as well as common types and structures.

NDC (EDIST) schemas are published under Passenger and Airport Data Interchange Standards Board (PADIS) governance (PSC Resolution 783) and according to PADIS publication procedures and release calendar. NDC (EDIST) 17.1 Schemas form a part of PADIS Message Standards Release 17.1 (available in full on PADIS extranet site to registered users).

NDC business requirements change management is under the Passenger Distribution Management Group Working Group (PDMG WG) governance, previously Distribution Data Exchange Working Group (DDXWG), where resulting change requests to the XML schemas are subject to PADIS change management, approval and publication processes.

Below is the description of the message pairs available in NDC (EDIST) 17.1 PADIS Release Schemas. Please note that the following messages have been removed from these versions: AirDocExchangeRQ, AirDocCancelRQ/RS, AirDocVoidRQ/RS, AirDocRefundRQ/RS
