For decades, airlines competed on three things: network, fleet, and price. These continue to matter. But another factor has quietly moved to the centre of the contest: how quickly an airline can change what it sells, how it sells it, and who it sells through.
An airline that wants to launch a checked bag bundle for a new route, offer a differentiated price to a corporate traveller, or make a new fare available directly on a travel agency platform would once have measured that work in months. Today, the airlines pulling ahead are trying to measure it in days.
The reason is not a new aircraft or a cheaper fare. It is the digital infrastructure underneath. More specifically, it is the application programming interfaces, or APIs, that allow one system to speak to another securely, consistently, and in real time.
Aviation has never lacked ambition. What has often slowed the industry is the complexity of its technology landscape. A single journey touches airlines, travel sellers, aggregators, payment providers, airports, loyalty programmes, and several other partners. For years, many of these connections were built in a rigid and highly customised way. Adding a new agency channel, a new ancillary product, or a new servicing capability often became a fresh technology project.
That model cannot keep pace with travellers who now expect the same speed, personalisation, and flexibility from an airline that they already experience in retail, banking, and other digital services.
This is where IATA’s New Distribution Capability, or NDC, becomes important. NDC is often described as a distribution standard, but its relevance is much wider. It represents a shift towards a more open, flexible, and API led aviation ecosystem.
Traditional distribution was built for an earlier era. It often reduced an airline’s product to a fare, a booking class, and a few codes. Modern airline retailing requires much more. Airlines need to present seats, bags, meals, lounge access, bundles, offers, and servicing options in a way that reflects their brand and commercial strategy.
NDC, supported by modern APIs, allows airlines to make richer content available directly to travel sellers and platforms. At Verteil, our Direct Connect platform works on this principle. What we see across markets is clear. Once the connection is API led, launching a new offer, entering a new market, or enabling a new seller relationship becomes far less dependent on long and repeated integration cycles.
The change is not limited to selling. Some of the most important improvements in airline retailing happen after the booking is made. Changing a booking, reissuing a ticket, processing a refund, or servicing a disrupted journey are not glamorous parts of the travel experience, but they often decide whether the customer trusts the channel.
For a long time, servicing was where digital retailing broke down. A traveller could book online, but still had to depend on a call centre or manual intervention when something changed. API led servicing can allow the same channel that created the order to modify, refund, or service it. That is a significant shift for airlines, travel sellers, and customers alike.
Payments are another example. Airlines today need to support different currencies, local payment methods, settlement flows, and compliance requirements across markets. Connecting payment capabilities through standardised interfaces is far more scalable than creating separate arrangements for every partner or geography. Frameworks such as IATA’s Financial Gateway also point to the industry’s broader move towards more connected and standardised payment infrastructure.
Perhaps the most important impact of APIs is on partnerships. No airline can build every capability on its own to a best-in-class standard. Fraud prevention, payment orchestration, loyalty, merchandising, servicing, and analytics often require specialist expertise. APIs allow airlines to work with the right partners without losing control of their core strategy.
This is also the practical answer to legacy lock-in. The future is not necessarily about replacing every old system in one large transformation programme. For many airlines, the more realistic path is to create a modern digital layer that connects the systems that still work with the new capabilities the business needs. Modernisation can then happen step by step, guided by commercial priorities rather than vendor constraints.
Technology, however, is only an enabler. Real transformation still depends on leadership, clear business intent, and the willingness to challenge long-standing ways of working. APIs do not decide what an airline should sell or which customer segment it should focus on. They simply reduce the gap between making a decision and acting on it.
That is the real shift. When distribution, servicing, payments, and partnerships run on open interfaces, airlines gain the freedom to experiment, respond, and scale faster. In the next decade of global aviation, the winners may not simply be those with the largest fleets or the deepest technology budgets. They will be the airlines whose digital foundations allow them to adapt, while others are still waiting for change to move through the system.
