KLM’s first Airbus A350-900, named after Rembrandt’s The Night Watch, finished its test flights in Toulouse in early September 2026 and is due to start passenger service Amsterdam–Toronto on 23 October 2026 — the start of a 22-aircraft renewal that replaces the A330s and some 777s by 2030. The aircraft carries 331 seats: 34 in the new KLM A350 business class, branded World Business Class, 26 in Premium Comfort, 33 extra-legroom and 238 standard Economy seats.
Except that, at first, nobody will sit in the front. The business seats are Stelia Aerospace’s Opera platform and their certification is incomplete after what KLM calls a revised interpretation of the rules by the aviation authorities, so the first two A350s will fly with 34 empty suites and sell only Premium Comfort and Economy. Here are the facts, what the cabin will be, and what to book in the meantime.
KLM A350-900: Key Facts
- Delivery and first flight: test flights completed in the week of 10 September 2026, with KLM expecting delivery later in September; the first commercial flight, Amsterdam–Toronto, is now scheduled for 23 October 2026 after two postponements from the original 27 September, five times weekly at launch; KLM names Montreal, Kilimanjaro, Dar es Salaam, Nairobi and Zanzibar as the destinations that follow
- Name: “The Night Watch”, after Rembrandt’s 1642 painting, continuing KLM’s naming tradition
- Layout: 331 seats — 34 World Business Class, 26 Premium Comfort, 33 Economy Comfort (extra legroom) and 238 Economy
- Business seat: Stelia Aerospace Opera, the platform Etihad uses on its A321LR; certification not yet complete, so the cabin is unsold on the first two aircraft with no published date for it to open
- KLM’s statement: “The seat manufacturer is working hard to complete the certification process as quickly as possible and make this cabin available to passengers ASAP.”
- Order: at least 22 A350-900s, all delivered by 2030, replacing the A330-200/300 fleet and some Boeing 777s
- Cabin: quieter cabin, better air quality, new lighting and lower fuel burn than the A330s it replaces
- Fares: business not on sale for the A350 flights; see below
KLM A350 Business Class: You Can See It but Not Book It
KLM’s current World Business Class is a Jamco Venture 1-2-1: without doors on the 787s, and with a sliding door on the retrofitted 777s — the seat I flew to Bali in August, and the best lie-flat bed I have slept in for a long time. The A350 was meant to be the next step: the Stelia Opera seat, a staggered 1-2-1 with a door, that Etihad and others have certified on narrow-bodies but which now faces a fresh reading of the rules for this installation.
It is the same story that delayed Lufthansa’s Allegris, Singapore Airlines’ new cabins and Air India’s 787-9s — seat certification has become the slowest part of launching an aircraft — and KLM chose to fly the plane rather than park it.
The practical result is odd: a brand-new aircraft with 34 unoccupied business seats, sold as a two-class flight. Premium Comfort, KLM’s 2022 premium economy, becomes the top cabin on the Toronto route until the doors open.
What to Book Now, and When to Wait
The A350 is scheduled to run Amsterdam–Toronto five times a week from 23 October, with Montreal and KLM’s East African routes named as the next destinations; the second aircraft follows in the same condition. Anyone who wants the new KLM A350 business class should wait for KLM to announce certification and then check the seat map — a 34-seat 1-2-1 cabin in rows one to nine will replace the current “no business class” listing. Until then, KLM’s best existing business class is the retrofitted 777 with the doored World Business Class suite, which is what flies Amsterdam–Denpasar via Singapore.
For readers flying Amsterdam–Bali, the relevant question is whether the A350 reaches the Southeast Asian routes before the business cabin is certified; KLM has not said. The other nonstop from Amsterdam into the region is now Vietnam Airlines’ Hanoi service, a SkyTeam partner with onward flights to Denpasar.
Tip: if the A350 appears on your route with only Premium Comfort and Economy on sale, that is the certification gap, not a downgrade of the route — the business cabin will open on the same aircraft later.
KLM’s Long-Haul Product, First-Hand
I have not flown the A350 and this is a preview. I flew KLM’s Amsterdam–Denpasar 777 in business in August 2026 — my KLM business class review rates it 4 out of 5, for an outstanding new suite let down by the service around it — and my other yardstick remains Etihad’s 787-9: a 1-2-1 with a mattress topper that I rated 3.5 out of 5 for the seat and the fare, marked down for catering and a crowded lounge.
Etihad’s A321LR flies the same Opera seat family KLM has chosen, in a two-seat First cabin, so the platform is known — what I want to see is KLM’s version of it, and whether the Crown Lounge at Schiphol keeps up.
How Much Does It Cost?
Business class is not on sale on the A350 flights until certification completes, so Amsterdam–Toronto on the new aircraft is priced as Premium Comfort and Economy only; KLM’s other Toronto frequencies on the 787 and 777 sell business as normal. KLM does not publish rack fares. Flying Blue award pricing for KLM business is dynamic, and the airline sells business at the same fare regardless of aircraft, so once the cabin opens the seat map — not the price — will tell you whether you have the new seat.
Flight prices do move between platforms. The same business class seat on the same date is not always the same price on the airline’s own site, Trip.com and Expedia: point-of-sale currency, consolidator fares and what is bundled into the ticket can shift the fare by a few percent — and occasionally by much more on premium cabins booked out of Asia.
So before I pay I run the same dates through Aviasales, which scans dozens of booking sites at once, then check Trip.com (often the sharpest on Asian routes) and Expedia (strongest when you add a hotel to the same booking). One caveat: a ticket bought through a booking site is changed or refunded through that site, not the airline, so read the fare rules before you buy.
KLM A350 Business Class: FAQ
When does the KLM A350 business class go on sale?
Not yet. KLM says certification of the Stelia Opera World Business Class seats is not complete after a revised interpretation of the rules by the aviation authorities, and it has published no date. The first two A350s fly with the 34 business seats empty and sell only Premium Comfort and Economy.
When does KLM’s first A350 start flying?
The first A350-900, The Night Watch, is scheduled to start Amsterdam–Toronto on 23 October 2026, five times a week, after two postponements from the original 27 September. KLM names Montreal, Kilimanjaro, Dar es Salaam, Nairobi and Zanzibar as the destinations that follow.
What seat is in the KLM A350 business class?
34 Stelia Aerospace Opera seats in a staggered 1-2-1 layout with a door — the platform Etihad uses on its A321LR. KLM has not yet published the screen size or bed length.
Which KLM business class should I book to Bali now?
Amsterdam–Denpasar via Singapore, flown by a retrofitted Boeing 777 with KLM’s doored World Business Class suite, which I rated 4 out of 5 in my KLM business class review.
A new aircraft, a new seat and 34 empty suites — KLM’s A350 is weeks away from Toronto, and the KLM A350 business class is some way behind it.
