All Rights Reserved. Foreword In developing the IATA standard for the New Distribution Capability (NDC), it has become apparent that there are a number of items which, whilst not appropriate for inclusion in the text of the standard, are fundamental to obtain a clear understanding of how NDC could be implemented. Thus there is significant benefit in documenting these, to promote a common understanding of the ways in which NDC can be implemented. Consequently, this Implementation Guide provides clarifications and explanations of the concepts and scope underpinning NDC. This publication is intended for business and technology individuals considering or actually involved in the implementation of systems and processes that will utilize NDC standards. Whilst it is written with the Airline in mind as the primary audience its contents will be useful for any implementer of NDC, whether they be an Airline, Seller or Aggregator. It describes best practice processes of the standards in a simplified manner and does not enter schema-specific details such as the actual element and attribute names, as found in the schemas’ data structure – rather, it aims to complement the explanation of process flows with high-level illustrations of messages designed to be easily comprehensible to first-time adopters of the standards. However, it should be noted that this publication is not a binding document - the formal texts relating to NDC are contained in the appropriate Resolutions and Recommended Practices adopted by the IATA Passenger Services Conference. This fourth edition of the guide has been produced by the PDMG Implementation Guide Task Force set up to oversee the revision and updating of the previous version 4.0 of the Implementation Guide. The Implementation Guide Task Force was established in April 2015 during the PDMG-WG9 meeting. Many individuals contributed to the development and provided valuable subject matter expertise to update and enhance this publication.

The NDC Implementation Guide This NDC Implementation Guide is published pursuant to IATA Passenger Services Resolution (PSC) 787, adopted by the IATA Passenger Services Conference during its 18-19 October 2012 meeting in Abu Dhabi. The United States Department of Transportation (DOT) in granting final approval of Resolution 787 on 7 August 2014, accepted a set of conditions jointly submitted by IATA and Open Allies for Airfare Transparency. These conditions clarify the intended application of Resolution 787, and apply to all Airlines globally that wish to implement NDC (DOT’s final order approving Resolution 787 and the accompanying conditions can be found using the following URL: http://www.regulations.gov/document?D=DOT-OST-2013-0048-0459 This guide was produced by IATA’s NDC team, with support and collaboration of the PDMG Working Group. This document aims to: Present the NDC program vision, objectives, benefits and scope Illustrate how Airlines and their partners can use the NDC Standard Explain details of the Standard Show examples of how the NDC Standard might be implemented This implementation guide is for general use, and is publicly available on IATA’s NDC website at http://www.iata.org/ndc. This document looks at NDC essentially through the lens of the Airline stakeholder. IATA’s goal over time is to include additional perspectives from other stakeholders. To this end we would welcome feedback that would enable us to enrich the views from the perspective of Sellers, IT providers and others.

All Rights Reserved. 1 About the NDC Implementation Guide 1.1 Structure of the NDC Implementation Guide The NDC Implementation Guide supports companies in the process of implementing NDC and contains an explanation of the NDC environment and guidance on developing potential areas of an NDC project (without presuming to define what a project should cover). The guide is divided into five sections. The first two sections give a high level view of NDC in the Airline context. The later sections provide technical information to support a team considering developing or implementing systems based on the NDC Standard. The first section of the guide contains explanatory notes on the guide itself, and other information useful to understanding the context of the material in the guide. The second section informs the reader of NDC’s scope. There is also a commentary on the opportunities NDC presents for Airlines. The third section drills down into related functions that NDC uploads/Management/ ndc-implementation-guide.pdf
