How Airline B2B Distribution Actually Works in 2026

Should an airline choose GDS or NDC?

Most airlines do not choose: in 2026 they run both GDS (global distribution system) and NDC (New Distribution Capability) connections, plus a growing set of direct and agent-facing channels on top. The more useful question is what each layer of B2B distribution actually does, and where the airline has room to change the economics.

This post breaks down how airline B2B distribution works today: the three layers underneath it, what NDC changed and what it didn't, and the newest variable: AI agents entering the booking chain.

What are the three layers of airline B2B distribution?

Airline B2B distribution has three layers: content and inventory (the fares and seats), connectivity (the pipes that carry them), and the agent-facing commerce layer (where someone searches and books). Each layer solves a different problem.

1. Content and inventory

Content and inventory is the fare, availability, and ancillary data itself: which seats exist, what they cost, and what's bundled with them. Every distribution model depends on this layer being accurate and current, and it's the layer airlines have historically had the least control over once content left their own systems.

2. Connectivity

Connectivity is the pipe that carries content from the airline to sellers: GDS connections, NDC APIs, and direct airline APIs. Connectivity determines who can reach the content and how much of it survives the trip. A traditional GDS pipe was built for a flat fare record; it wasn't designed to carry a personalized offer with bundled ancillaries, which is exactly why NDC exists.

3. The agent-facing commerce layer

The agent-facing commerce layer is where a human travel agent, or increasingly a piece of software, actually searches, prices, holds, and books. It's the layer travelers and their agents interact with, and it's the layer most B2B travel commerce platforms compete on: unified inventory across suppliers, markup and margin tools, ticketing, servicing.

Confusing these layers is why so many "GDS vs. NDC" conversations go in circles. GDS and NDC both live mostly in the connectivity layer. The commerce layer is a separate decision.

Why is traditional GDS distribution under pressure?

Traditional GDS distribution is under pressure on four fronts: cost, brand control, customer data, and retailing maturity. None of these is new, but together they explain why airlines keep revisiting distribution strategy.

• Cost. Legacy GDS distribution carries per-booking economics that scale against the airline as volume grows.
• Brand control. A fare distributed through a shared, undifferentiated pipe looks the same as every competitor's fare next to it.
• Customer data. When a booking is intermediated by a GDS and an agent, the airline often doesn't own the resulting customer relationship or the data that comes with it.
• Retailing maturity. GDS pipes weren't built to carry the kind of dynamic, bundled offer that modern e-commerce retailing assumes is table stakes.

These pressures don't mean airlines should or can drop GDS distribution outright. Indirect channels still carry meaningful volume, and many corporate travel programs are built around GDS access. The realistic goal for most airlines is reducing dependency, not eliminating the channel.

What did NDC change, and what didn't it change?

NDC (New Distribution Capability) is an IATA data standard that lets an airline construct and transmit a richer offer (fare plus seat, bags, and other products bundled together) through the same B2B channel that used to carry a flat fare record. That's a real, structural change: it moves offer construction back toward the airline instead of leaving it to whatever the GDS pipe could represent.

What NDC didn't change is the connectivity problem underneath it. NDC solves a content problem: it lets airlines say more, and more accurately, about what they're selling. It doesn't by itself solve who or what can reach that content, and how. That distinction matters more in 2026 than it did when NDC was first adopted, because a new kind of consumer is showing up on the other end of these APIs: software, not people.

Corporate travel is a useful stress test here. Programs vary widely in how completely their travel management company (TMC) can actually transact NDC content end to end, which is less about airline readiness and more about how much of the downstream tooling (policy engines, expense integrations, and agent workflows) has caught up to NDC's data model. Adoption of a standard and operational readiness to use it are two different milestones, and airlines evaluating a distribution partner should ask which one they're actually being sold.

How are AI agents changing airline distribution?

The newest change in airline distribution in 2026 is that AI agents (software acting on a traveler's or a company's behalf) are starting to search and book travel directly, without a person clicking through a UI.

That raises the same question NDC raised, one level up. NDC solved how an airline hands a rich offer to a human-facing agent tool. The open question now is how an airline hands that same offer to an AI agent that isn't a person, doesn't have a browser session, and needs a standardized, machine-readable way to ask "what can I buy, and how do I buy it." Industry conversation this year has increasingly framed NDC and emerging AI-agent connectivity standards as complementary rather than competing: NDC still governs what the offer contains, while an agent-facing connectivity layer governs how software reaches it.

For airlines, the practical implication is the same one that shaped the shift from GDS to NDC: the businesses that keep their content well-structured and reachable through standard interfaces will have more say in how they're represented, whether the thing reading that content is a person or a piece of software.

How should an airline choose a distribution strategy in 2026?

An airline does not need to rip out existing infrastructure to modernize distribution. Most airlines run legacy GDS, NDC, and direct channels in parallel, so the practical work is deciding where to invest next rather than picking one standard and discarding the rest. A few decisions worth making deliberately:

Decide what you actually want to own. Customer data, the retail experience, and margin control are three separate things. An airline can prioritize one without solving all three at once, and being explicit about which one matters most this year focuses the technology decision.

Treat the agent-facing commerce layer as a build-or-buy decision, not an afterthought. NDC and modern connectivity get an airline a better pipe. What sits on top of that pipe (a branded portal where travel agents and TMCs actually search and book) is a separate product decision, and it's usually faster to license than to build.

Keep GDS and NDC running in parallel deliberately, not by default. Dependency reduction is a gradual shift in volume and negotiating leverage, not a cutover event. Set a target and measure against it rather than treating "we're on NDC now" as the finish line.

Where does altovo fit?

altovo (formerly easyGDS) is a travel commerce platform, and its Airlines product covers two of these layers: NDC-native architecture with GDS and PSS (passenger service system) interoperability at the connectivity layer, and a white-label, branded booking and agent experience at the commerce layer. That lets an airline modernize distribution without discarding existing contracts or rebuilding its retailing stack from zero. Malaysia Airlines, for example, runs its own branded holiday booking site on altovo, connected to its Enrich loyalty program. altovo's airline platform goes live in under 8 weeks.
