Timothy O’Neil-Dunne is usually provocative and always interesting and his recent thoughts regarding specific technology and commercial issues linked to NDC are no exception. While ultimately concluding that, “Airlines and other stakeholders in the airline distribution marketplace need to focus on adoption of NDC, rapid deployment and sponsorship of innovation,” Timothy is unsparing in his critique of NDC as having “lost its way,” while its goals and promise have “become clouded by different agendas and competing forces.”
With regard to different agendas and competing forces—we have certainly reached out to other players in the travel distribution value chain whose agendas may well diverge on some issues from those of IATA and airlines—but there is more that unites us than divides us. And we want NDC to be an inclusive standard, broadly supported across the value chain.
Unfortunately, much of his most thought-provoking analysis lies outside of the scope of IATA’s activities—we do not get involved in or comment on commercial issues involving our members and we have emphasized that NDC is a standard, not a business model.
However, we can respond to one of his biggest concerns: that NDC is taking too long to arrive in the market, which in his view ultimately is putting at stake the very benefits it promises to deliver to the industry.
I’m sure everyone associated with NDC would like to move faster but in building a standard that isn’t always possible, particularly one that offers such a dramatic change and which is being developed with broad input from a number of different participants in the travel value chain. Think about the transition to e-ticketing, which also was a multi-year project. Arguably, NDC touches on even more stakeholders and more business activities.
And in fact, NDC has achieved significant progress, particularly over the past twelve months, especially in the areas of:
- Standard development – where working with 30+ industry partners, IATA has been able to put together a complete set of business requirements and XML schemas for the most critical steps of the airline distribution process (Shopping, Booking, Payment & Ticketing, Interline and Servicing)
- Industry stakeholder management – where through regular contacts with the travel trade global distribution systems, industry suppliers and corporate travel buyers, IATA is gaining acceptance for NDC from more and more industry stakeholders.
Other aspects of NDC are not entirely under the control of IATA for example:
- The need for airlines and their technology and distribution partners to prepare their respective organizations to NDC and evaluate and execute the process change and investments associated to NDC;
- The technical limitations of market-leading Passenger Services Systems (PSS), which prevents developers to source airline’s rich and unique content in an easy, agile and immediate manner;
Still, there is a need for greater speed in standard deployment and greater access to the schemas by the developer community and we expect to see progress accelerate as the Resolution 787 approval process at the US Department of Transportation is completed this summer.
As IATA increases its focus on industry adoption of NDC during this second phase of the program, we are excited about upcoming developments which include the release of the end-to-end schemas, a new study on business traveler needs and two other exciting projects which we expect to announce at the World Passenger Symposium, 15-17 October in San Diego. These initiatives will move us further down the NDC path. And they will help to deliver the key success factors that Timothy cited: “deliver value, deliver speed, deliver what the user and his/her consumer want”.
If you have visited the NDC web page recently, you may have noticed that an “Alignment” tab has been added to the top of the page. But what exactly is an "Airline Alignment" session?
Conducted by 2 experts from the NDC team, these sessions, which are approximately four hours in duration, bring together senior representatives from different departments within the same airline: revenue management, distribution, e-commerce, sales, marketing, IT, revenue accounting, finance and government affairs.
The session is structured around three well-defined objectives:
- Ensure a common understanding, across the airline, of the NDC Standard and the benefits it can offer
- Review the potential changes in the distribution process (shop, book, pay, ticket and settle) with all impacted departments
- Understand the airline's assessment of the opportunities and their position regarding NDC
And it is organized around four building blocks:
- Description of the NDC program and the scope of the NDC standard
- Review of the end-to-end distribution process today and in an NDC world
- Examples of the benefits delivered by NDC to the airline
- Discussion on next steps
So far this year, five airlines have participated in alignment sessions: SAS, Aeroflot, Emirates, Etihad and Iberia. In the next 3 months, we have another 10 sessions planned with other airlines in the European, Middle East-Africa and Asia-Pacific regions.
These sessions constitute the first step in these airlines’ journey towards NDC, leading to possible pilot projects with their preferred technology and agency partners.
As we speak, our team together with XML Working Group is busy working on a new version of the NDC schemas. Version 1.1 will provide airlines and intermediaries with the capability to sell more air products and offer more shopping scenarios, such as buying ancillary services from interline partners.
A key aspect in the design of any schemas is their performance and feedback from the 2013 NDC pilots was that the Version 1.0 schemas were too heavy. So over the past couple of months, the schemas have gone on a strict diet, resulting in a significant reduction in payload sizes.
In more general terms, version 1.1 of the NDC schemas leverages a stronger architectural foundation; the schemas are more robust, reflect a new fault- and exception-handling approach to schemas design, and finally are compliant with World Wide Web Consortium (W3C) best practices.
It was possible to adjust and fine tune the NDC schemas in a matter of months owing to the soundness of the methodology for the development of the NDC standard:
- The Distribution Data Exchange Working Group (DDXWG) supports the definition of the business requirements and associated schemas.
- The NDC Pilots validate the schemas and provide feedback and insights to the DDXWG for the next iteration.
The main limitation of this iterative approach is that, well, it is iterative! First adopters that have chosen to test earlier versions of the NDC schemas will need to migrate to the latest versions in order to benefit fully from the improvements. In view of the costs associated with migrating to newer versions of the schemas a “translation tool” will be included in any new releases. This tool will convert an NDC XML message from one version to another version of the same XML, for example from a 1.0 message into a 1.1 format.
If everything goes according to plan, Version 1.1 should be ready in August. Access to draft releases/work in progress will also be possible between now and then.
A rising number of players across the distribution value chain are recognizing the benefits that the NDC Shopping standard will bring: greater product differentiation, greater access to full and rich content and a greater and more transparent shopping experience for the customer.
One of the areas I am often asked about has to do with the assembly of the offer: with the NDC standard, airlines will be able to make sales offers to travel agents without them being prepared by intermediaries – just as airlines do today through their websites.
But how can this be done efficiently? A crucial innovation in NDC, which is not present in the Open Axis and other XML shopping schemas, is the formal tagging of an offer with an ‘Offer ID’ which links a price to a specific set of products. It lists the flights, specifies the payment conditions, the arrangements for making changes and clarifies ancillary products that are included - as well as the price of course.
As a result, the NDC messages become much ‘lighter’ and functional. The airline that created the product offer has ticketing and accounting built entirely around this offer, with no reliance on data from the intermediary except for the chosen payment method. The new controls for order management and ticketing against the ‘Offer ID’ should ensure that the fare to be paid is indeed the valid offer and so eliminate the need for revenue integrity checks and ADMs.
Of course, airlines, agents and aggregators will each need to make their own implementations of the NDC schemas. Airlines will also need to decide individually how much of the full NDC schema will be implemented when it comes to booking and ticketing. For example some airlines may choose to just implement NDC shopping and request their GDS/Aggregator perform booking and ticketing services.
So why did the earlier XML schemas not include an Offer ID which makes all this possible? I don’t know, just like I don’t know why the Romans never introduced the concept of zero in mathematics. The Romans never managed to develop mathematics to an advanced level, and airlines and agents that miss out on the Offer ID won’t get the full benefit of the NDC standard!
Two weeks ago, we enjoyed significant progress with regards to standard development, as representatives from 7 IATA Member airlines and 9 System Providers and other business partners gathered at our Geneva offices for the PADIS Messaging Week to:
- Review and validate the business requirements for NDC Booking, Airline Profile, Interline (for ancillary services only)
- Examine the business requirements for NDC Payment & Ticketing
- Review and validate the change requests to the NDC Shopping schemas (version 1.0)
What is PADIS?
The PADIS Board develops and maintains Electronic Data Interchange and XML message standards for passenger travel and airport-related passenger service activities. For instance, the PADIS message standards support the following application areas:
- Publication of schedules and slot management
- Airline shopping
- Reservations and electronic ticketing, including electronic miscellaneous documents
- Airport resource management and airport handling, including baggage handling
- Data exchange between airlines and governments concerning passenger data (PNRGOV)
- Data exchange between airlines and airports for operational flight related data (AIDX)
- XML schemas for exchange of data on the bar coded boarding pass (BCBP)
What came out of last week’s PADIS?
The PADIS Board responded positively to the submissions as it confirmed that the business requirements for NDC Booking and Interline (for Ancillary Services only) were seen as generally fit for purpose, when those include the descriptions of the data elements in individual messages.
The business requirement for NDC Payment & Ticketing also received positive comments while the requirements for Airline Profile are still a work in progress.
Based on the results, the DDXWG’s XML Group will now proceed with reviewing the feedback over the coming two months with a view to enhancing these business requirements and developing the XML schemas to support them; the task force was meeting in Boston last week to come up with a first draft of the schemas.
As a result of this very positive Messaging Week, an extraordinary PADIS meeting will be scheduled for late June via a series of conference calls to review the amended business requirements and proposed schemas.
This is great news for all the innovators and travel startups out there who are keen to start looking at the schemas more closely, in order to develop new ways of retailing air products and deliver brand new air shopping experiences to leisure and business travelers.
The first anniversary of the NDC Pilot Phase--which began in February 2013—provides an opportunity to review the achievements and learnings of the past twelve months in this critical aspect of the NDC Program.
How many airlines are participating in the NDC Pilot Phase?
- Five airlines have launched pilot projects in cooperation with their respective technology (and for some, travel agency) partners
- Another six airlines are discussing the framework of a next round of pilot projects with the NDC team.
The five pilots that went live in 2013 are:
- “Endeavor” by American Airlines, together with JR Technologies and a consolidator
- “Skycouch” by Air New Zealand, together with JR Technologies and a consolidator
- “SkyDreamer” by Hainan Airlines, together with TravelSky and CTBA
- “Sunshine” by China Southern, together with TravelSky and Ctrip
- “Alpine” by Swiss, together with HP, PROS and Datalex
What’s the scope of the NDC Pilot Phase?
The first five pilots have focused on the NDC Shopping schemas, using in some instances the airlines’ existing booking and ticketing processes to fulfill the shopping request.
The NDC shopping schemas enable airlines to construct their full product offers and to merchandize their baggage, seat maps and ancillary services, using rich content, in an anonymous or personalized manner.
What’s been the main achievement of this first year?
On 29 November 2013, the Chinese online travel agency CTBA issued the first e-ticket resulting from an NDC-based shopping transaction through the TravelSky system. The booking was a one-way trip between Beijing and Hainan Island on flight HU7782 on Hainan Airlines.
Successfully processed, this booking demonstrated interoperability of the NDC Shopping schema with existing airline processes and that it can support China’s domestic travel.
What did we learn from this first year of pilots?
Our pilots provided us with a great amount of valuable feedback. As a direct consequence, we are fine-tuning the schemas so the messages can be more efficiently processed by airlines, with reduced impact on their inventory systems.
We will shortly release a version 1.1 of the shopping schemas. This new release will address performance/scalability issues, information model harmonization, compliance with W3C standards and offer consistent error/exception handling.
From a functionality perspective, this new release will support product-only shopping, calendar shopping, group shopping notification, and other functionalities.
While we await approval of Resolution 787 from DOT, we are advancing into the second year of the NDC Pilot Phase, we will make sure to share our learnings from the existing pilots as well as from those that will be initiated in the coming weeks and months.
Last week, I was in Montreal for the Distribution Data Exchange Working Group (DDXWG), a key element of the NDC program as it gathers and documents the industry’s business requirements that drive the definition of the NDC schemas.
This 6th DDXWG signaled that NDC is drawing broad industry input with more than 70 participants from airlines, travel trade associations and agencies, global distribution systems, and IT providers taking part in the various task forces. Among the new participants, we were delighted to welcome representatives from two new airlines and a leading travel metasearch.
Three days…and significant results!
As with every DDXWG, much was achieved during the three days of the meeting. Most significantly:
- The business requirements for Booking (Order Management), Airline Profile and Interlining (for ancillary shopping only) were completed;
- Based on the learning from the pilots, the changes to the NDC Shopping schemas were presented and agreed upon.
Many thanks for the valuable contributions of all participants!
DDXWG has become a central point for industry collaboration
This 6th edition confirmed that DDXWG is achieving its objective to facilitate the definition of the business requirements in a collaborative and effective manner.
In a brief survey conducted at the end of the meeting, more than 90% of the participants stated that the DDXWG either met or exceeded their expectations and they would like to participate at a future meeting and continue to contribute to the various taskforces.
At the end of March, DDXWG representatives will present the new and revised business requirements to the relevant Passenger and Airport Data Interchange Standards (PADIS) committees.
The objective is to have these committees:
- Review and comment on the new business requirements for Order Management, Airline Profile, Interline (ancillary shopping only) and Payment & Ticketing;
- Review and comment on the changes to the NDC Shopping schemas to ensure interoperability and to facilitate eventual approval by the PADIS Board for publication as a part of IATA standards.
PADIS Board approval of NDC standards is subject to US DOT approval of Resolution 787.
What is PADIS?
The Passenger and Airport Data Interchange Standards (PADIS) Board develops and maintains Electronic Data Interchange and XML message standards for passenger travel and airport-related passenger service activities.
PADIS is governed by Passenger Services Conference Resolution 783. The PADIS Board, consisting of up to 20 airlines, is supported by two committees (shown below) and a number of expert working groups.
- Communications Standards Coordination Committee (CSCC) is tasked to promote and oversee interoperability on the level of communications protocols and general implementation of data exchanges and maintains IATA Systems Communications and Reference (SCR) volumes.
- Data Dictionary and Schema Coordination Committee (DDSCC) is tasked to promote and oversee semantic interoperability across IATA standards and recently started building a common industry data model.
Corporate travel managers are vital to the travel distribution value chain, and their role will continue to grow as self-booking tools become the norm and business traveler satisfaction a rising area of focus.
We’ve have had the opportunity to speak recently with a number of managers in Europe about their requirements. As a result, we have identified five areas where corporate travel buyers will welcome products and solutions based on the NDC standard when it is adopted by their technology partners.
Reduction of out-of-system and out-of-policy bookings
Because the NDC Standard will facilitate the provision of up-to-date airline product and service information, business travelers no longer will have to search for this information and make supplementary bookings on airline websites and third party systems.
The NDC Standard will enable the distribution of ancillaries to their full extent including product features, services, prices, rules and conditions etc. This will give corporate travel manager full visibility over the exact and complete costs of one flight option versus another.
The NDC Standard will allow for the display of product attributes and ancillaries in a structured way, enabling corporate travel managers to precisely determine which products and ancillaries should be made available to travelers.
The NDC Standard will facilitate the provision of up-to-date information on airline products and services, so the corporate travel manager and the business travelers will no longer waste valuable time in researching product- and service-related information online.
The NDC Standard will enable the distribution of the airline’s entire offering, including any ancillaries. As a result the corporate travel manager will have all flight-related expenses into their system, translating into more complete and effective reporting.
On 28 January, Airlines International in partnership with NIIT Technologies hosted a webinar on the New Distribution Capability (NDC). If you were not able to attend it, you are welcome to listen to the recorded webinar.
The event, which was moderated by Airlines International Editor Graham Newton, featured presentations from Anil Batra, NIIT Vice President Global Head - Travel, Transportation and Logistics, Dieter Westermann, Senior VP Revenue Management & Pricing Strategies from Qatar Airways, and me. It provided an opportunity to share our thoughts to an audience of more than 450 industry professionals on subjects such as:
- The potential of the NDC Standard as a business growth enabler (through the latest version of the NDC Demonstrator with real airline data)
- The technology, software and systems requirements in an NDC-enabling environment
- The role of the NDC Standard in changing travelers’ shopping experience for a full service, high quality carrier
In parallel to this webinar, the organizers conducted a quick poll with the participants, asking them the following three questions:
- By when do you think NDC will be a norm in the industry, rather than a new phenomenon?
- Which are the most critical challenges for the implementation of NDC?
- Which are the most crucial benefit you think that can be realized from NDC?
The results of the poll showed that:
- The majority of respondents think the NDC Standard will become the norm in three to four years
- 63% of respondents see performance and scale to be able to handle agent requests as the most critical challenges for the implementation of NDC
- More than 80% of the respondents believe that NDC will drive increased value either through innovation, enhancing product offerings or increased customer satisfaction in airline product offering across their agency channels
Interestingly, these results are very much in line with our thinking and it is also reassuring to see that most respondents view NDC as a factor of innovation for the future products that airlines will market to travelers.
Check the charts below to get the full results of the poll.
The Institute of Travel & Meetings (ITM), the association representing more than 1,000 British and Irish corporate travel buyers released the results of a survey about NDC they recently conducted with Irish and British corporate travel buyers.
Presented at the Business Travel Show that took place in London this week, the survey demonstrates that awareness of NDC is reaching across the distribution value chain, as 58% of their members have heard of the program.
Interestingly, the survey also highlights that:
- 55% of corporate travel buyers in Ireland and the UK do not see NDC as contravening any privacy laws and regulations
- 70% see travel agents benefiting from the NDC Standard as it will enable them to access the entirety of an airline’s product and service offering
- 55% estimate that global distribution systems so far have not done enough to properly merchandise airlines’ unique offerings and enable them to efficiently compare these offerings
The survey also shows that greater communication regarding NDC between ITM members and their respective travel management partners is needed.
What does this mean to us? First, we must continue to strengthen our communication efforts so everyone involved in airline retailing has visibility and understanding when it comes to NDC. This blog is an important channel in this effort.
Finally, it confirms that corporate travel buyers are seeing the future benefits of NDC as a way to improve product differentiation and facilitate access to airlines’ entire product offering, resulting in a greater shopping experience for themselves and for business travelers. At that’s good news.
