Quick summary
Singapore Airlines will spend S$2 billion (US$1.56 billion) rebuilding the cabins on 41 Airbus A350-900 and A350-900ULR jets and its incoming Boeing 777-9 fleet, adding a first-class cabin to the ultra-long-haul A350-900ULR for the first time. The first aircraft enter service in the second half of 2027.
The A350-900ULR flies Singapore–New York, Los Angeles and San Francisco nonstop. Which aircraft gets retrofitted first will decide when the new seats actually reach those routes.
Singapore Airlines is spending S$2 billion (US$1.56 billion) to rebuild every cabin on its long-haul fleet — and for the first time, that includes first class on the aircraft that flies the world’s longest nonstop routes.
The A350-900ULR, the low-density variant that connects Singapore to New York, Los Angeles and San Francisco without a stop, currently carries only business and premium economy. Under the plan announced this week, it gains a first-class cabin with curved sliding privacy doors, a 32-inch 4K touchscreen and centre seats that convert into a two-seater sofa.
For anyone booking Singapore this winter, none of it exists yet. The products roll out progressively from the second half of 2027, aircraft by aircraft, across 41 retrofitted A350-900s and A350-900ULR jets plus the incoming Boeing 777-9 fleet.
The practical question for travellers flying from Europe or North America is not what the seats look like. It is which tail number is flying your date.
What the S$2 billion actually buys
The programme splits along two tracks. On the retrofit side, 41 in-service A350-900 and A350-900ULR jets will be pulled from service and rebuilt. On the new-build side, the full four-cabin layout arrives factory-installed on the Boeing 777-9 widebodies Singapore Airlines has on order. Neither track delivers a single fleet-wide switchover date.
Only one of those tracks changes the ultra-long-haul product.
The A350-900ULR will gain both the new business seat and a first-class cabin. The standard A350-900 retrofit stops at business. That distinction matters more than any seat specification: whether you can book first class on this airline will depend on the specific variant operating your flight, not on the route name in the search results.
First class gets companion dining and centre seats that convert into a two-seater sofa — a berth the airline calls the “largest double bed in the sky.” Entertainment runs through a 32-inch 4K touchscreen with spatial audio. Business class adds leather with bespoke embroidery, sliding doors and electronically adjustable centre dividers; its full-flat bed measures 79 inches long and up to 24 inches wide, with selected centre pairs convertible into companion beds when the divider drops.
Further back, the 777-9’s premium economy offers a 40-inch seat pitch, a leg rest with adjustable footrest and a four-way headrest. Economy gets wool-blend upholstery and a redesigned recline mechanism intended to free up knee and shin clearance.
| Route | Aircraft | Current layout | New first class |
|---|---|---|---|
| Singapore–New York (JFK) | A350-900ULR | 67 business, 94 premium economy | Yes — first time on this variant |
| Singapore–Los Angeles | A350-900ULR | 67 business, 94 premium economy | Yes — first time on this variant |
| Singapore–San Francisco | A350-900ULR | 67 business, 94 premium economy | Yes — first time on this variant |
| Future 777-9 routes | Boeing 777-9 | Four cabins, factory-installed | Yes — all four classes new |
The airline’s November 2026 product announcement sets out the full cabin family. An earlier 2024 release had projected the first A350-900ULR retrofit for the first quarter of 2027 — a narrower milestone than the broader rollout now described as starting in the second half of 2027. The airline’s own route history ties the ULR to the New York, Los Angeles and San Francisco nonstops, and the cabin specification annex lists the screen and seat-pitch figures in full.

Why the ULR is the hard part
The A350-900ULR is a fixed-density aircraft. It entered service in 2018 with 67 business-class and 94 premium-economy seats and no economy cabin at all, which is how it flies Singapore–New York nonstop. Adding first class means the airline has to find the space somewhere, and it has not published the new ULR seat map. Until it does, nobody can say how many business seats survive the change.
The direction of travel is clear, though. Fewer business seats on the same airframe means tighter KrisFlyer redemption on the world’s longest nonstops — the routes where premium inventory is already the scarcest thing in the network. Cash fares on those city pairs sit high enough that Air Traveler Club’s tracking occasionally flags temporary drops on Singapore routes lasting only a few days.
Cabin retrofits are scheduled around heavy maintenance checks, not around route launches. That is why an airline can announce a product two years before most passengers will ever sit in it — and why the second half of 2027 is a programme start window, not a date every route inherits.
There is a second timeline running alongside this one. Starlink connectivity arrives progressively from early 2027 on the A380, A350-900 long-haul and A350-900ULR aircraft, which means some passengers will get faster Wi-Fi on the old seat before the new seat shows up. For a fuller picture of what the current premium-economy product delivers on these corridors, see ATC’s breakdown of Singapore Airlines premium economy.
How to book around a phased retrofit
The new cabins are two years out, but the aircraft assignment on your booking is fixed at schedule publication — and that single field decides whether you get the new product or the old one.
Before you commit, open the flight-selection page on singaporeair.com and confirm the aircraft type, not just the route. During the rollout, an A350-900ULR, a standard A350-900 and a 777-9 will carry three different cabin mixes on overlapping city pairs.
If you are redeeming KrisFlyer miles or booking through a Star Alliance partner, check the aircraft assignment again once schedules open for late 2027. A first-class seat depends on the specific retrofitted airframe operating the flight, so the same route can offer the new cabin on one departure and not the next.
Watch: the first A350-900ULR retrofit entering service. The 2024 plan pointed to the first quarter of 2027, and that aircraft will be the earliest signal of how the new ULR cabin mix affects award availability.

Questions? Answers.
Will the standard A350-900 also get a first-class cabin?
No. Only the A350-900ULR variant gains first class. The standard A350-900 retrofit adds the new business-class seat and stops there, so first class on this airline will be limited to the ultra-long-haul aircraft and the incoming 777-9s.
When can I actually book the new cabins?
The airline describes the rollout as beginning in the second half of 2027 and progressing aircraft by aircraft. That is a programme start, not a fleet-wide date — individual routes will convert at different times, and the full four-cabin layout depends on Boeing 777-9 deliveries.
Does adding first class to the A350-900ULR reduce business-class seats?
The airline has not published the new ULR seat map, so the final count is unknown. The aircraft launched in 2018 with 67 business and 94 premium-economy seats and no economy cabin, which means a first-class cabin has to come out of existing space rather than added capacity.
Will the new Wi-Fi arrive before the new seats?
Yes, on some aircraft. Starlink connectivity is scheduled to roll out progressively from early 2027 on the A380, A350-900 long-haul and A350-900ULR fleets — ahead of the cabin retrofit programme’s second-half-2027 start.
