As airlines push toward full NDC, the industry’s most powerful distribution incumbents are doing something unexpected: agreeing with them. The question is whether their replacements will be ready in time.
For thirty years, the Global Distribution System was the undisputed centre of gravity in airline retailing. Every fare, every seat, every booking routed through Sabre, Amadeus, or Travelport. Airlines needed the GDS to reach agencies. Agencies needed the GDS to access inventory. The model was circular, self-reinforcing, and profitable for everyone at its centre.
That model is breaking apart. Not collapsing. Breaking apart. The distinction matters.
The GDS is not dying. It is being forced to become something it was never designed to be: a retail technology platform, an execution layer for AI-mediated commerce, a modular infrastructure provider in a multi-source world it no longer controls. The airlines accelerating NDC adoption did not cause this transformation. They exposed it. The underlying cause is a decade of structural change in how travel is shopped, sold, and serviced. The GDS players know it. Their responses, each different in method and risk, are the real story.
The Pressure Is Not a Negotiating Tactic
Air Europa will introduce a Distribution Channel Fee on all GDS bookings from 1 July 2026, and exit Sabre. Turkish Airlines added a surcharge on EDIFACT bookings and pulled low-fare content from GDSs in select markets. Lufthansa Group has been raising its Distribution Cost Charge across all three incumbents for two consecutive years.
Each move is framed, publicly, as a commercial negotiation. The aggregate signal is harder to dismiss: airlines are no longer using NDC as leverage. They are using it as infrastructure. The bluff has been called, and it turned out not to be a bluff.
This changes the GDS calculus fundamentally. The traditional response to an airline exit was to wait, because carriers almost always came back. Reach mattered more than cost savings. That logic is weakening. Every airline that leaves without visible consequences makes the next departure easier to justify.
The question is no longer whether the GDS model is under pressure. It is whether the new models incumbents are building will be ready before the pressure becomes permanent loss.
From Pipe to Platform: The Pivot Nobody Had a Choice About
The traditional GDS was a pipe. Highly efficient, globally scaled, remarkably reliable. But a pipe does not create value. It transmits it. That architecture was suited to an era of filed fares, fixed inventory buckets, and EDIFACT messages.
It is structurally incompatible with dynamic pricing, personalized offers, AI-mediated shopping, and modular airline retailing.
Sabre, Amadeus, and Travelport have all reached the same conclusion: the pipe business is shrinking. The platform business is where the next decade of value sits. But they are executing three meaningfully different versions of that pivot, with different risk profiles, different timelines, and different exposure to failure.
Sabre: The Execution Layer Bet
Sabre’s pivot rests on a single argument: as AI reshapes how travellers discover options, the real battleground will not be at the top of the funnel. It will be in the infrastructure layer that makes AI-generated demand executable. Booking confirmed. Ticket issued. Ancillary processed. Change serviced.
That argument is credible. It is also unproven at scale.
Sabre Mosaic, its modular retailing platform, moves airlines beyond static fare classes toward dynamic pricing based on trip purpose, willingness to pay, and real-time demand signals. Alongside it, Sabre is redesigning its commercial model away from the per-segment fee that defined GDS economics for four decades, toward outcome-based pricing across the full customer lifecycle.
Alessandro Ciancimino, Sabre’s Vice President of Airline Distribution EMEA, told TDN: “As retailing becomes more software driven and increasingly automated, the commercial model has to align with the value delivered by the platform, not the mechanics of a legacy booking.”
That is a fundamental redesign of the financial relationship between a GDS and its airline customers. It is also a significant commercial risk. Outcome-based pricing only works if outcomes are measurable, attributable, and consistently delivered. Sabre is asking airlines to trust a new economic model at precisely the moment those airlines are most sceptical of GDS value.
On AI, Ciancimino is direct: “Sabre is not competing for attention at the top of the funnel. It is building the execution layer that AI-mediated journeys depend on.” Strategically sound. But the risk is real: airlines building direct retailing infrastructure, and NDC aggregators filling the distribution gap, both reduce the volume flowing through that execution layer before Sabre finishes building it.
Ciancimino framed the core challenge plainly: “Running a handful of airline connections in isolation is very different from supporting dozens of carriers across regions, schemas, and servicing models, under peak volume and commercial pressure. Scale exposes the real challenges of NDC.” That applies as much to Sabre’s own ambitions as to anyone else’s.
Amadeus: The Most Ambitious Rebuild in the Industry
Of the three incumbents, Amadeus is making the largest structural bet. Not an evolution of the existing stack. A replacement of it.
Amadeus Nevio is a cloud-native, AI-native suite of modular retailing solutions built to operate independently of the legacy Passenger Service System. Its architecture is built around IATA One Order standards, consolidating flights, ancillaries, and third-party services into a single unified record that eventually retires the PNR, e-ticket, and EMD that have defined airline bookings for forty years.
The airline partnerships are substantive. British Airways selected Nevio as the backbone of its Offer and Order transformation, with Dynamic Offer Pricing rolling out for real-time contextual pricing. Air France-KLM chose Nevio to unify travel records across the group. Lufthansa Group, simultaneously raising its GDS surcharges, signed Amadeus as a key Nevio provider to introduce an Order ID replacing booking and ticket numbers across all ten of its carriers.
These are not marginal agreements. Three of the largest airline groups in the world are choosing Amadeus as the infrastructure for their next distribution era while continuing to pressure the legacy Amadeus GDS model. That tension is not accidental. Amadeus is trying to be on both sides of the transition. The risk is that the shift happens faster than the new stack can absorb it.
The production evidence is real. Finnair became the first airline globally to create a Native Order on Amadeus Nevio, built entirely on One Order standards with no legacy artifacts. Saudia followed. The industry had spent years questioning whether offer and order management would function at commercial scale. These milestones do not prove the architecture works everywhere. But they prove it works somewhere, which is further than most had gone.
On search infrastructure, Amadeus deployed Advanced Airline Profile, a machine-learning filter that blocks unproductive NDC queries before they reach airline systems. At Air France-KLM, it eliminated more than 70% of irrelevant traffic, reducing processing costs and improving look-to-book ratios. A proof of concept with Trip.com showed that pre-caching NDC offers in a cloud-based Offer Repository reduced airline system polling by 40% and improved search response times by 30%. If that approach scales, it resolves one of NDC’s most persistent weaknesses: its inability to handle high-volume, low-intent searches without overwhelming airline infrastructure.
Amadeus reported full-year 2025 revenue growth of 8.5% at constant currency, with Air IT Solutions up 8.7%, driven partly by incremental Nevio revenues. It entered 2026 confident enough to announce a 500 million euro share repurchase programme.
The financial position is strong. The execution risk is proportionally large. Nevio is the most ambitious retailing rebuild any distribution incumbent has attempted. British Airways, Lufthansa Group, and Air France-KLM are simultaneously its proof of concept and its most demanding clients. If Nevio delivers, Amadeus becomes the foundational infrastructure of modern airline retailing. If delivery slips, those same airlines have both the leverage and the options to go elsewhere.
Travelport: The Smallest Bet, the Clearest Logic
Travelport is not rebuilding a retailing stack. It is not competing to become airlines’ core technology partner. Its strategy is narrower and arguably more defensible in the short term: become the platform that makes NDC genuinely functional for agencies, by restructuring the airline-distributor relationship from the ground up.
The December 2025 agreement with United Airlines is the clearest expression of this. Travelport gains early access to United’s NDC technology roadmap and co-development rights. Engineering teams from both companies work jointly on capabilities for Travelport+, its modern retailing platform. The traditional model, where airlines build NDC systems independently and GDSs integrate whatever they get, is explicitly discarded.
Travelport’s Chief Commercial Officer Jason Toothman was direct: “That’s caused real pain points for travel agencies and corporates. Our goal is to evolve that so we can start to build tomorrow’s capabilities together.”
Practical outputs include integration of United’s Online Booking Tool extras, pooled unused travel credits, direct MileagePlus enrollment, and Jetstream amenity funds as ancillary payment, into Travelport’s Deem OBT platform for corporate travel. Initial capabilities launched in early 2026.
The United deal is the headline. The broader content expansion is just as significant. ANA NDC launched across 40 markets through Travelport+. Riyadh Air signed for NDC content distribution with full offer-and-order host system integration. LOT Polish Airlines, Royal Jordanian, and LATAM all expanded or renewed NDC agreements in the past twelve months. Travelport also extended its third-party developer network across Europe, connecting four technology companies to its JSON-based NDC APIs.
The strategic logic is coherent: absorb NDC complexity and deliver consistent, functional workflows to agencies regardless of which airline implementation they are working with. NDC, EDIFACT, and APIs on a single surface.
The risk is scale. Co-developing with United is meaningful. Co-developing with the breadth of airlines required to make Travelport+ the industry default is a different challenge entirely. Travelport is the smallest of the three incumbents. Its model requires airlines to invest engineering resources in a partnership depth that many carriers have historically resisted. If co-development scales, Travelport may have found the most efficient path through the transition. If it does not, the platform risks being well-designed but underpowered.
The Reality Check Nobody Is Publishing
There is a version of the NDC story the industry circulates in presentations and keynotes. NDC is the liberation of airline retailing. Direct channels win. GDSs fade. Carriers finally control their product.
That story is not wrong. It is dangerously incomplete.
Airlines that have gone live with NDC have discovered that connecting to a new API is the easy part. Making the full booking journey work consistently under real commercial conditions is a different problem. Comparison shopping across NDC and EDIFACT in a single workflow. Price stability between search and booking. Post-booking changes at scale. Disruption handling without routing agents to airline portals. Downstream integration with back-office and TMC systems. These are not edge cases. They are the daily operational reality every agency faces.
A 2025 Roland Berger analysis makes the gap concrete: 72% of airlines recognise the importance of Offers and Orders. Only 27% have begun transformation programmes. The offer side shows genuine progress. The order side, end-to-end management, servicing, settlement, and interline capability, remains in its infancy across most of the industry.
The content problem compounds it. In many markets, NDC content closely mirrors what was already available in EDIFACT, with limited differentiation and restricted retail flexibility. Agencies have no commercial reason to rebuild workflows for content that offers them nothing new. The API changes. The product does not. Full-scale adoption only accelerates when NDC delivers genuinely differentiated, dynamic offers that improve conversion, not when it serves as a more expensive transport layer for the same inventory.
Airlines pressing GDSs on cost while failing to invest in differentiated NDC content are solving the easier half of a two-part problem. And reducing their own leverage in the process.
The Honest Scorecard
Airlines are winning the distribution argument. That trend line does not reverse. More carriers will move content into NDC channels, introduce EDIFACT surcharges, and exit GDS contracts. Air Europa is not an anomaly. It is a signal.
What airlines are simultaneously discovering is that exiting the GDS creates a reach problem. Passive distribution narrows. The long tail of agencies that book a carrier without being actively sold to becomes harder to access and harder to quantify until it is gone. NDC aggregators are building businesses in that gap. The airlines who have already exited will find out how wide it is.
The three incumbents are making three distinct bets. Sabre is building the execution infrastructure for AI-driven demand, a credible position with unresolved scale risk. Amadeus is rebuilding the airline retailing stack from the foundation, with real production milestones but proportionally large delivery risk. Travelport is pioneering a co-development model that is structurally sound but dependent on airline appetite for a depth of partnership most carriers have historically avoided.
None of these bets are proven. All three are necessary.
The GDS that fails to transform will not survive the decade. The GDS that transforms badly will not survive it either. What remains open, and what the industry has not yet confronted honestly, is that only one or two of these platforms will likely emerge from this transition with the scale and commercial position to define what comes next. The rest will serve a shrinking share of a market that has already decided to move on. Air Europa’s exit is not a crisis. It is a countdown.
