NDC API Integration

BookingXML is a leading NDC API Integration Provider, we provide New Distribution Capability to travel agencies and travel management companies globally.




What is NDC API Integration?


NDC (New Distribution Capacity) is an XML standard developed by IATA to empower airlines to offer their passengers rich content and additional services like luggage, seat, and class selection. Rich content is the only key to staying ahead of the competition and building a unique brand image for airlines.

Collecting Passenger data through New Distribution Capability offers an excellent platform for exceptional pricing policy.

In the earlier data interchange process, GDSs followed the UN rules known as EDIFACT. Now, NDC is taking the place of the EDIFACT protocol. Since 1980 GDSs have been using EDIFACT, but now NDC is introducing new opportunities.

Modern protocol (NDC) implementing XML standards offers ample content and additional services to OTAs, GDSs, and destination management companies. XML standards are changeable, making NDC a dynamic tool.

XML is a basis for communication among airline passenger service systems, GDS, and NDC interfaces. Travel companies are in a position to get airline data in JSON format using REST APIs. One of the latest APIs manages the interchange of rich content.


Best NDC API Integration Company




BookingXML is a leading NDC API Integration provider that has been certified by the International Air Transport Association (IATA) as an IT provider.

We adopt IATA-approved Global Distribution Systems to allow the sale of tickets directly online through B2B, B2C, B2B2B, and B2B2C agents. We extend IATA software for travel agencies, tour operators, and travel aggregators, as well as ticket reservation software for Non-IATA travel members. 

Our system helps to control costs by achieving high performance, e-ticketing, interlining, and traditional GDS connections to all travel agency sales and distribution which conform with IATA standards.

Enhancing online travel software globally requires Flight API Integration from different best flight providers. The development of a travel portal is incomplete without the integration of flight APIs from various suppliers.

A cost-effective and effortless way to build customized and dynamic travel booking applications based on constantly evolving online travel technology means you must always need to upgrade day by day with the emerging travel industry.

Travel Management Companies can leverage the advantages of NDC by integrating with content aggregators such as global distribution systems more easily. NDC could be implemented in two ways, directly integrating into the airline Passenger Service System (PSS) or via an integration layer outside of the PSS. 

Airlines, Travel management companies (TMCs), online travel agencies, corporate buyers, global distribution systems, and other technology players contribute to the NDC Standard. An industry standard will help to improve the efficiency of the airline distribution system, which will benefit airlines, agents, GDSs, IT providers, and travel start-ups.

With NDC, airlines can also provide a wider range of approved offers through GDSs. We directly integrated NDC-enabled Airlines and suppliers including major consolidators. NDC enables Travel Agents to digitize their business by providing Custom Websites, Mobile Apps, Corporate Booking Tools, and many more tools and utilities. 

We provide comprehensive and seamless content integration via NDC connectivity. BookingXML allows airlines to distribute their content in real-time and sets a standard for the APIs available to TMCs, travel agents, travel aggregators, and corporates

We work with all the major GDS providers and travel consolidators and integrate with Amadeus GDS, Travelport GDS, and Sabre GDS which supports the operation of reserving airline tickets, hotel rooms, rental cars, and other travel sectors.

Our Travel API solution for integration with various bed banks, flight consolidators, GDSs, and other travel product suppliers provides easy and quick access to your booking platform. to activate any connecter, you must have a direct contract with the supplier, which allows you to negotiate the best price.


How One Can Use NDC API Integration for Distributing Airline Content?


Observing the current scenario of NDC API integration, one can use XML standards in different ways to supply airline content.

  • Airline NDC API

  • GDS NDC, and

  • NDC Interface for IT service providers

Let us understand these in detail!


Airline’s NDC API


Small airlines are taking time to adopt NDC as they see it as a risk. On the contrary, Major airlines like Lufthansa, Air Canada, and British Airways created their NDC API solutions. All solutions have their way to use.  For instance:

At first, Lufthansa introduced the NDC API solution that established a direct distribution channel between airlines and their customers. In a short span, Lufthansa got a level 4 certification that proves its adoption of distribution via NDC.

Their distribution channels include:

  • Travel agencies

  • Distributors

  • Aggregators

  • Suppliers

  • Website Developers etc.

The scenario of airlines accepting New distribution capabilities is progressive. One can depict that sooner or later, airlines have to adopt the NDC API integration for better services. NDC is a blended communication for selling directly or via GDSs.




For GDS aggregators, NDC implementation became a vital question so they decided to force the expansion of an XML standard across the industry. The process goes even further as all parties of a traditional distribution chain start working with NDC. Say, ATPCO offers the services of the NDC design team as well as the proprietary NDC Exchange technology. The fare aggregator also designed Routehappy — a tool for the distribution of visuals, videos, and other types of rich content from airlines.

All three major GDSs have ARM index certifications: Sabre and Amadeus as system providers for both airlines and sellers and Travelport as a system provider for sellers only. Yet, the number of NDC integrations and capabilities covered leave much to be desired. Besides that, the striking partnership with GDSs involves complex negotiations and significant investments.

Travelport was the first of the GDSs to develop the NDC channel. Сurrently, the NDC capabilities are available via their JSON-based Air APIs that also support traditional GDS offers. Six carriers provide rich content to the GDS — namely, Qantas, United Airlines, American Airlines, Singapore Airlines, and Air France-KML. However, the two last integrations don’t support booking seats or ancillaries. Overall, the GDS validated 13 capabilities with the ARM index. 

Sabre provides REST/JSON Offer and Order APIs to source NDC content from Avianca Group (Columbia), Qatar Airways, Qantas, Singapore Airlines, and United Airlines. The integration with American Airlines is ongoing. The GDS verified 22 ARM capabilities as a system provider for sellers. 

Amadeus made NDC a part of their Enterprise subscription meant for large travel players. The modern functionality is delivered via XML-based SOAP APIs that are quite complex and a bit outdated in comparison with REST APIs. The GDS allows for searching and booking content from American Airlines, United Airlines, Singapore Airlines, Air France-KLM, Qantas, Qatar Airways, and Iberia, with more integrations expected to come soon. It supports 23 ARM capabilities for sellers. 


NDC with flight aggregators


Flight aggregators are relatively new players in the airline distribution landscape. They establish direct connections with full-service and low-cost carriers (LCCs) as well as with GDSs to source NDC, GDS, and LCC offers. Travel vendors can reach this content via a unified API or a prebuilt booking tool.

Compared to GDS NDC, this option comes with more NDC connections (25-30 airlines on average), lower prices, a faster integration process, and more flexibility in terms of commercial negotiations and developing customized tech solutions.

On the dark side, “Aggregators often lack out-of-the-box connectivity with mid- and back offices which is very important to run operations in TMCs,” Ksenia Penkova warns. “These integrations still have to be developed and financed while GDSs already have them in place.” That’s one of the reasons why much of corporate travel stays with Amadeus, Travelport, or Sabre. It’s worth noting that some aggregators are already working on this problem and offer solutions to meet the needs of TMCs.


Advantages of NDC API Integration


Customized Booking Experience and Dig a Way To Customer Information.


  • In the existing scenario, airlines get only basic details of passengers, and online travel agencies, GDSs, and tour operators control the rest. Not getting enough information prevents airlines from offering a customized booking experience to customers. It is because they do not know their customer best. NDC API Integration broke this scenario and offered more freedom to airlines.  NDC communication protocol aims to allow airlines direct access to their customer information.


Freedom to Decide on Travel content and Price Quotation


  • A customized shopping experience offers airlines a platform for flexible pricing for their customers. Airlines take support from the Airline Tariff Publishing Company (ATPCO) to decide their fare.

  • Third-party involvement is cutting down the profit and customized pricing opportunities for airlines. Here New Distribution Capability API Integration comes into the picture. It empowers airlines to quote customized prices and holiday packages using different passenger details.

  • By implementing modern XML standards, airlines are in a better position to create their separate APIs. Further, it allows them to update fares and generate special deals for individual customers based on their experience with an airline.


Platform to Offer Additional Services, Concessions, and Best Holiday Deals


  • Airlines follow EDIFACT (Electronic Data Interchange for Administration, Commerce, and Transport) as a communication protocol. These protocols allow the transfer of documents and files between multiple nations and sectors. Although airlines accept those protocols, it prevents them from offering additional services like customized packages. Ultimately EDIFACT is doing no good for airlines as they are losing their share of the revenue.


Build a Competitive Edge by Creating USP


  • Existing GDS software restricts the freedom of airlines.  It allows airlines to reflect fares and schedules and no other value-added services. It enables travel agencies to control pricing, prevent airlines from offering rich content, and create a competitive edge. NDC API integration solves this concern for airlines. Now they have the freedom to do whatever they can to make their product unique and competitive.




  • Usually, airlines rely on Passenger Service Systems that reflect the booking details, prices, flight schedules, etc. PSS displays the availability of the seats, but it took time to accept updates. NDC API came as a more reliable system for airlines by which all their valuable services, fares, and schedules can directly reflect passengers. The travel booking experience becomes convenient and joyful for passengers.

  • It was first introduced in September 2015 and ensured a change in how airlines market their services. You can say that it is an update to the Passenger Service System. Further, it allows online travel agencies, destination management companies, and tour operators to get customized data via GDSs.
