Sabre's MCP Claim: Same Toll Booth, New Road

Eric Marketts

On Monday, September 21st, Sabre published a press release with this headline: "MCP Is the New NDC." We've said on this show before that MCP and NDC aren't competitors — they compose. One is domain vocabulary. The other is generic plumbing. Sabre just told the market they're the same thing. They're not. And why Sabre needs you to believe that is the through-line for this week.

Steph Nell

Welcome back to The V1 Airline Retailing Report. I'm Steph Nell.

Eric Marketts

And I'm Eric Marketts. Last week we ended on one line. The number that decides the outcome is the one nobody publishes. This week Sabre published a number: nearly eighty customers on its AI agent layer. What it didn't publish is what it charges them. And in the same release, the pipe manufacturer named itself the new standard. Three stories. Story one: the Sabre press release, what it actually claims, and why the framing is a business move, not a technical statement. Story two: the same day Sabre was selling agencies on MCP, T2RL Engage opened in London, and the airline-side vendors were selling something different. Story three: on day two of T2RL, Kenya Airways announced a full platform migration to Sabre. One carrier, two distribution vendors, one very clear signal.

Steph Nell

The through-line is this. When the intermediation is threatened, the intermediary renames the standard. Same toll booth. New road.

Eric Marketts

Let's get into it. Before we get into the press release, I want to make sure everyone has the same vocabulary. We've covered this on the show before. What is MCP, and what is NDC, and why does it matter that they're different?

Steph Nell

NDC is IATA's New Distribution Capability standard. It defines what an airline offer contains — fare families, seat maps, ancillary bundles, servicing rights, the whole order structure. It is vocabulary. It tells a travel system what a fare is, what a bag costs, what an upgrade includes. NDC is content-aware by design. It exists specifically because airlines needed machines to understand what they were selling, not just a price and a flight number.

Eric Marketts

And MCP?

Steph Nell

MCP stands for Model Context Protocol. It was published by Anthropic in late 2024. It is a standardized way for AI models to connect to external data sources and tools. It is not content-aware. It does not know or care what a fare is. It is a pipe. A generic, content-agnostic API protocol that lets an AI agent read data and take actions through a defined interface. MCP could connect to an airline. It could also connect to a weather service, a stock market, or a pizza ordering system. The protocol has no opinion on what it carries.

Eric Marketts

So one is a vocabulary for airline content, and the other is a general-purpose connection protocol. Different jobs.

Steph Nell

Completely different jobs. And they compose. An airline builds NDC-compliant offers — the product logic, the bundle rules, the dynamic pricing. MCP connects an AI agent to the API that exposes those offers. NDC builds the content. MCP pipes it to the agent. Neither replaces the other. You need both or neither reaches the traveler.

Eric Marketts

That's the setup. Here's what Sabre said this week. On September 21st, Sabre published a press release across Nasdaq, PR Newswire, and its investor relations site. The headline: "MCP Is the New NDC — Is This Travel's Shift-to-Streaming Moment?" The subtitle reads: while competitors announce plans to modernize, Sabre already has — and its customers are live and benefiting from AI because of it. Sabre launched its MCP server in September 2025 — one year ago. As of this release, they claim nearly eighty customers piloting or in full production on that server. And Sabre says it's live inside ChatGPT and Claude today. Virgin Australia won the Skift 2026 Idea award for its conversational AI flight search, powered by Sabre's MCP architecture.

Steph Nell

The numbers are real. One year live, eighty customers — agencies and OTAs booking through an AI agent layer connected to Sabre's inventory. Virgin Australia winning an industry award for it. None of that is spin. The deployment exists and it works.

Eric Marketts

So what's wrong with calling it the new NDC?

Steph Nell

The deployment is real. The claim is a market positioning move. MCP doesn't define what a fare is. It doesn't tell the agent what the bag costs or what the bundle rules are. It pipes the data that NDC — or whatever content standard the airline chose — already encoded. When Sabre says MCP is the new NDC, it is telling buyers that the agent connection layer is the thing that matters, and the content that goes through that connection is secondary. That benefits Sabre. It positions Sabre's MCP server as the essential infrastructure, regardless of what the airline did with its product and offer strategy for the last decade.

Eric Marketts

Bull case — is there one?

Steph Nell

Yes. Sabre shipped it and it's in production. For any seller — a TMC, a corporate booking tool, an OTA — building an AI agent today, Sabre's MCP server is the fastest path to live airline inventory. One integration reaches the airlines in Sabre's network. That's the same value proposition that made the GDS compelling in 1985, now running on a 2024 protocol. Eighty customers made a rational choice. If you need to book flights through an agent, this works and it's live. Virgin Australia's Skift award isn't marketing. It's an airline that moved product through an AI interface and won revenue from it.

Eric Marketts

And the bear case.

Steph Nell

The bear case is the economics. Airlines pay the GDS roughly six dollars a segment on average, and more under some contracts. Sabre's MCP server sits in the same position as its GDS — between the seller and the airline inventory. The seller connects to Sabre, not to the airline. The airline filled that seat through Sabre's infrastructure. Same toll booth, new road. And there's a second problem. Sabre saying MCP is the new NDC is strategically useful because it implies the decade of work airlines did on NDC content — the product structures, the bundle logic, the dynamic pricing rules — is now obsolete, just another legacy format the new protocol supersedes. It's not. NDC content is what makes an AI agent's offer actually differentiated. Strip it out and every airline looks identical in the agent's response. Commoditized inventory, Sabre in the middle, same as 1985.

Eric Marketts

And the critical take.

Steph Nell

We've said on this show that MCP and NDC compose rather than compete, and that the versus framing was a sales tactic. Sabre just proved it publicly. The press release frames MCP as a replacement because Sabre could not win the NDC content war. Airlines that built NDC content can, in theory, reach agents directly through aggregators and direct APIs. Sabre's MCP server is Sabre's answer to that threat: make the agent connection layer its platform, collect the toll there instead of at the booking record. The protocol changed. The intermediation logic didn't. Watch the fee schedule. When Sabre publishes what it charges per MCP-originated booking, that number will tell you everything the press release doesn't.

Eric Marketts

The same day Sabre published that press release, hundreds of airline technology leaders were gathering in London for T2RL Engage. Walk me through what T2RL is for anyone who hasn't been in the room.

Steph Nell

T2RL is Travel Technology Research Limited — an independent airline industry research firm. Their annual Engage conference is the working session for airline IT and distribution strategy. Not a trade show, not a GDS vendor event. Airline executives, PSS providers, and distribution technology companies in the same room, measuring real progress. The agenda this year ran September twenty-first through twenty-third at Sancroft in London. Day one was airline-only workshops: continuous dynamic pricing, interlining in an Offer and Order world, and distribution. Days two and three were the main stage. The theme was The Journey to Value. That phrasing matters. Not "value unlocked." Journey to. The industry is mid-transition, not done. And look at the knowledge partner list: Accelya, Amadeus, Flyr, and Sabre. Hold that thought.

Eric Marketts

What was on the agenda?

Steph Nell

The core question was how to move Offer and Order transformation from architectural ambition to measurable outcomes. Workshops covered retailing, AI, distribution, dynamic pricing, and payments. The specific phrasing in the agenda was how airlines sustain momentum, structure effective partnerships, and identify where value is still being left on the table. Five promise areas tied to Offer and Order transformation. This is the industry measuring itself against the commitments it made three years ago. The airline names on the program tell you who is doing the measuring: distribution and technology leaders from carriers including Alaska, Southwest, Qantas, Virgin Atlantic, and Riyadh Air.

Eric Marketts

That's the setup. Here's what happened at the conference. Infosys showed up at T2RL with an Offer and Order pitch. Not a roadmap — a live demonstration of AI-powered retailing: Offer and Order management, dynamic pricing, intelligent merchandising, personalized traveler experiences, data-driven revenue optimization. Infosys frames this as accelerating the airline's retailing journey with AI-first solutions. One day after Sabre told agencies that MCP is the new NDC and that content reform is yesterday's work, Infosys was on a stage in London showing airlines what content reform actually produces when it's live. Infosys also hosted a panel called "Damage Control," with the chief commercial officer of Aegean and a TAP executive, on look-to-book ratios and what AI traffic does to airline systems. That's the airline side admitting the agent channel has a cost problem before it has a revenue story.

Steph Nell

That's the counterposition. Sabre's audience is travel sellers. T2RL's audience is airlines. Two different buyers, two different messages, in the same week. Sabre tells the agency: plug into our MCP server and reach airline inventory. Infosys tells the airline: build your Offer and Order capability and give the agent something worth reaching. These messages are not in conflict. But they imply very different answers to who controls the product.

Eric Marketts

And the airline-side data showed up too. On September twenty-second, Accelya released numbers it said it was presenting at Engage. Half of Lufthansa Group's indirect bookings now run through NDC. Corporate NDC bookings on Accelya's platform are up a hundred and sixty-nine percent year on year. Ancillary attach rates run up to three times what EDIFACT delivers. Accelya's line for the week: NDC is no longer the destination. It is the foundation.

Steph Nell

Read that next to Sabre's headline. One side says NDC is yesterday's standard. The other says NDC is the floor everything else is built on, and brings Lufthansa numbers to prove it. Same week, same content, opposite conclusions. And both conclusions put the speaker in the middle of the transaction.

Eric Marketts

And Verteil?

Steph Nell

Verteil's pitch this year is agentic airline retailing. Verteil is an NDC-native aggregator and distribution platform — they connect airline NDC content to travel sellers without going through a traditional GDS. Their position is the same one they've held for two years: modularity and openness are the only way airlines get to control their own offer in a world of AI agents. Agentic retailing built on airline-controlled NDC content, routed through an open aggregator, sold without a GDS in the middle. That's the architecture Verteil is selling. And it's the direct answer to Sabre's MCP press release, pitched to exactly the audience that was in London that week.

Eric Marketts

Bull case for the airline-side pitch at T2RL?

Steph Nell

The bull case is that the architecture Infosys and Verteil are selling is the only one that gives the airline margin control in an agentic world. If the agent connects to Sabre's MCP server, the airline's offer is one of many items in Sabre's inventory response. If the agent connects to a Verteil rail with airline-controlled NDC content, the airline's offer is differentiated by the product logic the airline built. In an era where AI agents compare options and rank them, the airline with structured, machine-readable, differentiated content outperforms the airline whose inventory looks like a price and a seat count. Offer and Order is how you win in the agent channel without paying a toll for every booking.

Eric Marketts

Bear case.

Steph Nell

The bear case is timing. "Journey to Value" as a conference theme tells you the value is still en route. T2RL's agenda was explicitly about how to sustain momentum and find where value is still being left on the table — which means plenty of it still is. Sabre launched its MCP server a year ago and has eighty customers. How many airlines have live Offer and Order production revenue? A handful globally. The airline-side architecture is structurally superior. It's also three to five years behind the agent-layer infrastructure the GDS vendors just built. First mover advantage in the agent channel may have already gone to the intermediary while the airline was still building its offer.

Eric Marketts

Bridge to story three.

Steph Nell

Here's the question that story three answers. If you're a mid-size airline watching this week unfold — Sabre's MCP press release on Monday, T2RL's Offer and Order main stage on Tuesday — what do you actually buy? Keep that question in mind, because one airline answered it publicly that same Tuesday.

Eric Marketts

Before we get to the announcement, set the context. Kenya Airways is a SkyTeam carrier, forty-two destinations, primarily in Africa. What's their distribution history leading into this week?

Steph Nell

Kenya Airways had already moved to NDC content distribution through Amadeus. In 2025, they went live with NDC content on the Amadeus Travel Platform, becoming one of the first Sub-Saharan airlines to do it. They had a legacy PSS — a system that had been running their reservations, ticketing, inventory, and airport operations for more than twenty years. The NDC layer was added on top of an old foundation. That's the common pattern: modern distribution standard, aging operational core. The announcement this week addresses the foundation, not the distribution layer.

Eric Marketts

That's the setup. Here's what Kenya Airways announced on September 22nd — day two of T2RL Engage. Kenya Airways selected Sabre to implement a modern retailing platform across the airline. The press release came out September 22nd, joint from Nairobi and Southlake, Texas. The platform runs on Sabre Mosaic — Sabre's modular Offer and Order architecture. It replaces Kenya Airways' core reservations, ticketing, inventory, and airport check-in system. Twenty-plus years on the old stack. Kenya Airways also announced a separate partnership with Branchspace. Branchspace's Trip-lake platform becomes the digital commerce layer — the booking interface customers interact with directly. The initiative is called Project Kifaru, Swahili for rhino. Three vendors: Sabre for the operational core, Branchspace for the direct channel, and Amadeus still holds the NDC distribution relationship.

Steph Nell

The timing is not coincidental. Sabre publishes "MCP Is the New NDC" on September 21st. Kenya Airways announces a full Sabre Mosaic migration on September 22nd. Sabre's commercial team had a very good week. This also answers the question I posed at the break: if you're a mid-size African carrier watching the MCP and Offer and Order debate, you buy the Sabre PSS. That is the decision Kenya Airways made, in public, in the middle of the week Sabre defined itself as the agent-layer infrastructure.

Eric Marketts

Bull case for Kenya Airways?

Steph Nell

The bull case is real. Sabre Mosaic is modular. Kenya Airways can migrate in stages and unlock value incrementally. The Offer and Order capability — continuous pricing, dynamic bundling, personalized ancillaries — is baked into the same platform as the PSS. Branchspace Trip-lake gives the commercial team direct control over offers in the direct channel without IT dependency. For a carrier that spent twenty years on a legacy stack, this is a genuine transformation. And Kenya Airways is not just buying technology. It's buying positioning: Sabre Mosaic is the same platform that positions the airline for the agent channel, through Sabre's MCP server, when agents become a material booking channel.

Eric Marketts

Bear case.

Steph Nell

The bear case is concentration, and it ties straight back to story one. Kenya Airways now runs its PSS and its Offer and Order capability on one Sabre platform, its NDC distribution through Amadeus, and its direct channel on Branchspace. Three vendors, and Sabre holds the core. Now add what Sabre said the day before: its MCP server is the agent connection layer, with eighty customers already on it. If that becomes the default path AI agents use to reach airline inventory, Kenya's offers, built on Sabre Mosaic, reach the agent through Sabre's rail by default. The airline paid to modernize its retailing and still pays a toll at the agent layer. That's the same intermediation model the three big GDSs turned into roughly seven billion dollars of distribution revenue last year, rebuilt on a modern platform. That figure is Amadeus and Sabre's reported numbers plus our own estimate for Travelport, which is private and doesn't publish. Kenya Airways is a more sophisticated retailer than it was last week. Whether it has broken the dependency depends on where the agents go.

Eric Marketts

And the critical take.

Steph Nell

Kenya Airways' NDC content lives in Amadeus. Its operational backbone is now Sabre Mosaic. Its direct digital commerce runs on Branchspace Trip-lake. And Sabre would very much like its agent channel to run through Sabre's MCP server. Ask this question: in five years, when an AI agent books a Kenya Airways seat, which of those three vendors collects a fee on the transaction? If the agent routes through Sabre's MCP, the answer is Sabre. If the agent routes through an open aggregator to Kenya's Amadeus NDC content, the answer is Amadeus and possibly the aggregator. If the agent reaches Branchspace's direct channel, no GDS is in the middle. Kenya Airways just spent significant capital to have all three paths available simultaneously. That's optionality. But it's also three separate bills for the same seat sale. The airline that wins the agent channel isn't the one with the most paths. It's the one that controls the path the agent uses most. Kenya Airways just bought the infrastructure to fight for that. The outcome depends on which rail the agents run on by 2028 — and that decision is not Kenya Airways' to make alone.

Eric Marketts

Three stories, one week, one argument. Sabre calls MCP the new NDC to position its agent-layer infrastructure as the essential rail. T2RL Engage shows airline-side vendors building the counter on the same days — Offer and Order content that makes the agent's offer worth routing. Kenya Airways announces a full Sabre Mosaic migration on day two of T2RL, and ends the week with Sabre at the core of its stack and positioned to own its agent channel too. The protocol changed. The intermediation economics didn't. And the carrier making the biggest technology bet of the decade is doing it inside the same vendor relationship the industry has been trying to restructure for ten years.

Steph Nell

And can we just admire the choreography for a second? Monday, Sabre tells the market NDC is yesterday's standard. Same Monday, Sabre is a knowledge partner at a conference about getting value out of Offer and Order. Tuesday, Sabre sells Kenya Airways an Offer and Order platform. Accelya says NDC isn't the destination, it's the foundation. Flyr says it's the only Offer and Order platform live today. And every one of them has a slide explaining why it belongs in the middle of your transaction. Nobody in this industry is an intermediary anymore, Eric. We're all enablers now.

Eric Marketts

Enablement. Billed per segment.

Steph Nell

Here's what I'd say to someone new to this industry trying to understand why this week matters. The GDS was the original pipe between airlines and travel agents. Airlines spent a decade and billions of dollars building NDC to reduce their dependence on that pipe. Now the pipe manufacturer is calling itself the AI agent connection layer, shipping it in production, and signing a flagship African carrier to a full platform migration, all in the same week. If you want to know who wins the next decade of airline distribution, don't watch the press releases. Watch the fee schedule Sabre publishes for MCP-originated bookings, watch whether T2RL's "Journey to Value" becomes a destination rather than a theme, and watch whether Kenya Airways' Amadeus NDC distribution layer still gets used when Sabre's MCP server offers a faster path. Those three numbers will tell you more than anything said at a conference.

Eric Marketts

If this episode sharpened your thinking on how the distribution stack is actually being rebuilt, share it with someone evaluating a technology partnership or distribution strategy right now. These decisions are being made this month, not in 2028. We've said before that MCP and NDC are composable tools. This week proved that the companies in the middle know it and are moving to own both layers before the airline does. We'll be back next Monday.
