Who are the Suppliers?
Suppliers in this post refer to any air content provider, be it Global Distribution Systems (GDSs), Airlines, IT providers who act as Technology Middle Ware provider for Airlines, Passenger Service Systems (PSSs), consolidators or even content aggregators.

Who are the Online Players?
Online Players in this post are any Online Travel Agents (OTA’s), Business to Business (B2B) providers, Global Distribution Systems (GDSs) and Meta Search Engines (Meta’s.)

For any online player to be successful, the most important content is Air. All along, this air content came primarily from Global Distribution Systems (GDSs) and/or Low Cost Carriers or consolidators like Travelfusion. This made it easy for any OTA or B2B provider to manage connectivity as there were fewer variations or changes from the GDSs or LCCs. All that they had to do was integrate three GDS systems, the LCCs and the Consolidators for air content. Unlike airline websites, where different brands are showcased within the same cabin using rich media, most of the online players display only the lowest fare.

With the introduction of IATA’s New Distribution Capability and Airlines aggressively pushing for NDC Content, the scenarios have changed. In addition to the GDS and LCC integration, online players are left to integrate individual NDC airlines as well. As airlines evolve as retailers and turn to showcase their products in its entirety with rich media, OTA’s or B2B providers will have to integrate third parties like Route Happy also to measure up.

The New Distribution Capability (NDC) was envisioned in the IATA Resolution 787 almost seven years ago. Since then, there has been a great deal of activity around refining the XML schema and redefining the business requirements for flight shopping, order creation, managing payments and accountable documents.

As of June 2021, 99 airlines are NDC Certified, out of which 51 of them hold ‘Level 4 with FULL Offer and Order Management certifications’, 17 airlines are ‘NDC@Scale certified’, 23 airlines are ‘Level 3 Certified with Offer and Order Management’, 4 airlines are with ‘Offer Management’ and 4 airlines with ‘Post Booking Ancillaries’ as per IATA’s NDC Registry. Each of these different levels use different IATA NDC Schemas. Additionally, 70 IT providers that offer products based on the NDC standard for Airlines and Sellers/Aggregators bring their own versions or schemas. Going forward, IATA plans to release two new versions of the NDC schema over the next two years.

The challenge is real for a small-scale Online Travel Agency or B2B provider to manage these various integration’s (GDS + LCC + NDC airlines + Route Happy etc), ensuring up-to-date versions and schemas from various technology providers and the cost, risk, time to market them.
