KLM’s first Airbus A350, named The Night Watch after the Rembrandt painting, is entering service on the Amsterdam to Toronto route with all 34 World Business Class suites sealed off. The seats have not cleared certification in time for launch.
A New Flagship Jet, Minus Its Flagship Cabin
KLM confirmed the delay in a statement on its own newsroom, saying that “due to a revised interpretation of regulatory requirements by the aviation authorities, certification of the World Business Class seats has not yet been completed.” Delivery of the first jet is due at the end of August 2026, with the inaugural commercial flight to Toronto following in September.
The A350 seats 331 passengers: 34 in World Business Class, 26 in Premium Comfort, and 271 in economy. Premium Comfort is available from day one, and KLM says business-class ticket holders will be accommodated in that cabin instead until the seats are cleared, Simple Flying reported.
Only the first two A350s are affected for now. KLM has not given a date for when the business suites will actually open for booking, saying only that the seat manufacturer is working to finish the process as quickly as possible.
Not the only airline hit
Delta ran into a similar certification snag earlier this year with the premium seats on its A321neo aircraft, a sign this is a wider industry bottleneck rather than a one-off KLM problem.
Why the Same Seat Needs a Second Sign-Off
The seats in question are built on the Stelia Aerospace Opera platform, and a version of that same design is already flying today on Airbus A350s at Air France, under the same European regulator that oversees KLM.
Regulators do not certify a premium seat as a standalone product. They certify it as installed, including its exact floor attachment points and its distance from the nearest emergency exit, because those details feed directly into the crash-test data an airline has to file for that specific cabin.
A different production batch or a slightly different cabin layout on KLM’s A350-900 can be enough to require a fresh review, even though the seat model itself is not new. It is the same underlying issue behind a string of seat-related airworthiness directives across the industry this year, including one on the 737 MAX.
The bigger picture
As premium cabins pack in more moving parts, sliding doors and deeper recline, certifying them is getting harder, not easier, which is why more airlines are hitting these delays right before high-profile launches.
The A350 is the centerpiece of a €7 billion KLM fleet renewal that also includes new Embraer E195-E2s, Airbus A321neos, and Boeing 787s. KLM has at least 22 A350-900s on order, with deliveries continuing through 2030, so how quickly this first certification issue is resolved will set the tone for the rest of the rollout.
