Accelya has released new data at T2RLEngage 2026 with Lufthansa Group as its case study, putting numbers behind a claim the industry has repeated informally: airlines that moved fast on NDC are starting to see it pay off, while others are still weighing whether to start.
Half of Lufthansa Group’s indirect bookings now flow through NDC, with selected strategic travel partners already at 100 percent. Ancillary attachment rates through those NDC channels run up to three times higher than what the airline sees through traditional EDIFACT distribution, and on tickets where an ancillary is attached, Accelya’s platform data shows up to $76 in incremental revenue per ticket.
NDC Was Never the Point
The single most useful figure here isn’t the 50 percent or even the $76. It’s what the $76 implies: that revenue doesn’t come from connecting to NDC, it comes from what an airline does once it’s connected. Richer offers, better merchandising, continuous pricing instead of static fare buckets.
That reframes what “NDC progress” should mean. Connectivity percentage, booking share, number of integrated sellers, these are proxies. They describe how plumbed-in an airline is, not how well it’s retailing. Lufthansa Group’s numbers are notable because they show the second thing, not just the first: ancillary attachment three times higher through NDC, and a modular distribution architecture built so the airline can combine capabilities and partners around its own strategy rather than depend on a single vendor stack.
Tye Radcliffe, Chief Customer Success Officer at Accelya, made a version of this argument directly, describing NDC as infrastructure rather than a milestone, and arguing that the airlines pulling ahead are the ones using that foundation to build better offers, manage orders and automate servicing rather than simply reporting connectivity numbers.
The Corporate Curve Is Bending Faster Than Expected
Corporate NDC bookings across Accelya’s platform grew 169 percent year on year as of July 2026, and one major corporate travel program grew NDC bookings more than 56-fold over the same period. Accelya attributes the jump to content, servicing and traveler experience working as one system rather than three separate problems.
Corporate travel has historically been slower than consumer retail to adopt new distribution technology, constrained by policy controls, duty-of-care requirements and longer procurement cycles. A 56-fold increase inside that environment is a notable data point, and it’s consistent with the same pattern above: once the servicing and policy layer catches up to the content layer, adoption can move quickly even in a risk-averse segment.
Puck Voorneveld, Senior Director Distribution & Payment at Lufthansa Group, described the shift in similar terms, calling Modern Airline Retailing a commercial imperative already producing measurable financial and customer benefits rather than a strategy still being tested.
Read the Data for What It Is
This is worth stating plainly, because it shapes how much weight the numbers should carry. Both figures come from parties with a direct commercial interest in this narrative: an airline mid-transformation on retailing, and a vendor whose platform processes roughly half of global NDC volume. The specific figures come from Accelya’s own systems and have not been independently verified.
That doesn’t make them wrong. It means they show what two of the most invested players in NDC are able to demonstrate right now, not necessarily what a typical airline should expect on a comparable timeline. The release also doesn’t break the numbers down by route, market or cabin, and offers no comparison against airlines running NDC at similar scale on a different platform. Lufthansa Group and Accelya make a strong internal case. On the data provided, it isn’t yet an industry-wide one, and NDC adoption globally remains far from uniform, with plenty of carriers still early in the connectivity stage this data set has already moved past.
A Shift in What the Competition Is About
Read together, these figures point to a shift worth naming: the competitive question for airlines with NDC live is no longer simply whether they’ve connected. It’s whether they’ve built the commercial and operational capability to turn that connectivity into better offers, higher ancillary attachment and more revenue. That’s an analytical read of this specific data set, not a claim that every airline’s NDC debate has been resolved.
For carriers still early in that process, the practical implication is about what kind of gap they’re closing. Matching connectivity is a procurement decision. Matching merchandising sophistication and order management maturity is a longer build, and Lufthansa Group and Accelya’s numbers suggest that gap, where it exists, compounds rather than stays fixed.
