Singapore Airlines has confirmed a delay to its long-awaited new First and Business Class cabin products, with the first retrofitted Airbus A350 Long Haul jet now due to enter service in the first quarter of 2027, rather than the previously communicated Q2 2026.

The new four-seat First Class cabin set for the carrier’s A350 ULR fleet, which had been pencilled in for a Q1 2027 debut, has been pushed back to an unspecified later date.

Background

When Singapore Airlines announced its S$1.1 billion cabin retrofit programme in November 2024, the original timeline called for:

• Q2 2026: New Business Class enters service on the first retrofitted Airbus A350 long-haul aircraft
• Q1 2027: New First Class (and Business Class) enters service on the first retrofitted Airbus A350 ULR aircraft

These seats are long-awaited, and already long-delayed.

They were originally due to enter service with the carrier in 2021 on brand new Boeing 777-9s, but with that programme repeatedly pushed back, SIA opted to retrofit them onto its Airbus A350 Long Haul and Airbus A350 ULR fleets first.

Premium Economy and Economy cabins will also be refreshed as part of the programme.

Cabin reconfiguration

Here’s how the refits will alter the seating layout on the Airbus A350 Long Haul aircraft.

Singapore Airlines Airbus A350 Long Haul
Cabin	Current	New	Change
Business Class	42	42	—
Premium Economy	24	24	—
Economy	187	192	3%
Total Seats	253	258	2%

Interestingly the Airbus A350 Long Haul fleet will effectively retain its current configuration, with the exception of the Economy Class cabin, where five additional seats will be squeezed in post-refit.

The cabin split on A350 ULR aircraft will see the most significant shake-up, with a brand-new four-seat First Class section reducing Premium Economy capacity by nearly 40%.

Cabin	Current	New	Change
First Class	—	4
Business Class	67	70	4%
Premium Economy	94	58	38%
Total Seats	161	132	18%

What’s slipped, and why

SIA confirmed the delay this week, with a spokesperson telling local media:

“Singapore Airlines’ first retrofitted Airbus A350-900 long-haul aircraft is expected to enter service in the first quarter of 2027, subject to regulatory approvals.

“The revised timeline reflects industry-wide supply chain constraints, as well as a delay in the certification of one of the new seats.

“We will provide an update on the entry-into-service of SIA’s retrofitted A350-900 ultra-long-range aircraft at the appropriate time.”

SIA spokesperson, May 2026

That’s a slip of at least six months, and potentially as long as nine months, on the A350 Long Haul timeline, and an open-ended timeline for the A350 ULRs.

The delay won’t surprise anyone watching the broader Business Class seat supply chain.

Safran, one of the largest seat manufacturers in the industry and a contender for SIA’s new Business Class seat with its ‘Unity’ product, delivered 2,632 business class seats globally in 2025, an increase of just 150 units (+6%) year-on-year.

That’s modest growth for a market where airline demand for next-generation premium cabins is running well ahead of available production capacity.

It’s also worth noting how the two issues SIA cites likely map to the two seats.

The A350 Long Haul, which receives only the new Business Class, now has a firm Q1 2027 entry-into-service, suggesting the supply chain constraint is the determining factor there – a production capacity issue, rather than an approval one.

The certification delay, by contrast, almost certainly refers to the new First Class seat, which is only being fitted to the seven A350 ULRs, a fleet that now has no committed launch date.

A 14-year wait

This will come as a disappointment to many Singapore Airlines First and Business Class regulars keen to sample the new products, which will also bring Starlink Wi-Fi, an all-new KrisWorld entertainment system, and what the airline describes as “elevated dining and amenities” to the long-haul fleet.

The seats will now likely be christened “2027 J” and “2027 F”, marking a significant gap in long-haul seat evolution for the carrier, which last meaningfully refreshed these products in 2013, with “2013 J” and “2013 F”, both of which now feel well out of step with the competition.

2013 J	July 2013

2017 J	November 2017

2027 J	Q1 2027

While the “2017 J” seat was launched on the carrier’s Airbus A380s, that was very much evolution rather than revolution over the 2013 J model, and has limited coverage on the network, appearing only on those 12 superjumbos.

The 2027 J will therefore mark the first genuine step-change in long-haul Business Class cabin design at SIA in nearly 14 years.

While there’s still nothing fundamentally wrong with the 2013 J seat, which boasts direct aisle access and converts into a flat bed, there are many industry developments in this cabin that now make it look and feel rather dated.

We’ve flown on this seat many times and it’s still broadly a comfortable experience with lots of space on offer and nice finishes, and many passengers prefer its wide and open feel over ‘coffin-like’ closed-door designs other airlines have been introducing.

However, the main bugbears are the necessity to flip the seat over to convert it into bed mode, and the requirement in most seats to sleep at an angle with your feet in a small cubby hole below the side console of the passenger in front.

There’s also the increasingly notable lack of the latest ‘bells and whistles’ in the current product, like USB-C ports, wireless charging, Bluetooth headphone pairing and larger 4K in-flight entertainment screens – not to mention the latest trend in Business Class – closing privacy doors.

These are all more or less ‘de rigueur’ in the latest Business Class cabin products being rolled out by competitors, including Qatar Airways’ Qsuite, JAL’s latest A350-1000 Business Class, and even British Airways’ Club Suite, which we recently put to the test.

Unveiling pushed to later in 2026

The new cabins were originally set for a 1H 2026 launch event, as we reported in May last year.

SIA now says that unveiling will happen later in 2026, to better tie in with the delayed in-service launch of the new Business Class.

That’s a sensible call, since there’s little benefit in showing off a brand new product six months or more before passengers can actually experience it.

A350 ULR: signs of a longer slip

The picture on the A350 ULR fleet looks rather less encouraging.

Earlier this year we predicted Los Angeles as the most likely first refitted A350 ULR route from Q1 2027, based on the airline’s emerging schedule changes.

However, SIA has now postponed the start of A350 ULR retrofit downtime.

Where the airline had previously been pulling one aircraft out of the seven-strong fleet from November 2026, that has now been officially shifted to January 2027, and with Economy Class sales inventory zeroed out on SQ33/SQ34 San Francisco services through all of January 2027, it’s looking increasingly likely at the time of writing that’s about to slip again – to February 2027.

If that holds, it represents a three-month delay on the A350 ULR programme already, potentially pushing the first refitted A350 ULR (and the new First Class with it) into Q2 2027.

It’s worth stressing that SIA is not yet hanging its hat on any particular timeframe for these jets, so the above should be taken with a pinch of salt, but the signals don’t point to any acceleration at this stage.

If anything, the open-ended ULR timeline is consistent with the suspicion raised earlier, that it’s probably the new First Class seat having certification issues, which by its nature is a less predictable constraint than the supply chain issue we suspect probably affects the new Business Class.

What can we expect from the new cabin products?

Singapore Airlines is still giving relatively little away about the new seats at this early stage, ahead of its launch event later this year that will see the reveal of both new cabins, among other service enhancements.

However, the airline has promised that the new products will set “a new industry standard” and “a quantum leap of service and product”, something we’re all excited to see.

What we know so far is that each closed-door suite in First Class has angled doors, and with four in total a single-row 1-2-1 configuration is likely for the Airbus A350 ULR, while the exact seat count and layout for the Boeing 777-9 is not yet confirmed.

The design also includes an elaborate blind built into the window shades, not dissimilar to those found on business jets.

Here’s SIA’s short teaser video for the new 2027 First Class seat.

Business Class will still certainly debut ahead of First Class, on Airbus A350 Long Haul aircraft from Q1 2027, and here we will see closing doors for suite-style privacy from the aisle.

Artist’s impressions don’t give too much else away at this stage, though we can see that there are alternating window-aligned and aisle-aligned seats at each row, in common with the airline’s latest Regional Business Class layout.

That opens up the opportunity for ‘honeymoon’ options at alternate rows in the middle section, potentially meaning double beds for couples.

In both cabins we expect modern touches like USB-C charging ports, wireless charging pads and Bluetooth headphone connectivity, while IFE screens should also inch bigger, along with the general industry trend.

Wi-Fi will also get much faster, with a new Starlink system making its way to these aircraft during the refit process.

Here’s SIA’s short teaser video of the new 2027 Business Class seat, so you can start to judge for yourself what to expect.

As we mentioned earlier, don’t forget that the airline is actually promising a wider upgrade – not just to its First and Business Class seats, but also to dining, amenities, and KrisWorld entertainment – in a move clearly designed to keep pace with (or hopefully exceed) top-tier competitors on long-haul routes in the years ahead.

The 777-9 will also debut in 2027

Another interesting piece of the ‘new cabins puzzle’ is that Singapore Airlines still expects to take delivery of its first Boeing 777-9 in 2027, as we covered last October.

Despite numerous delays over the years, the 777-9 programme now appears to be roughly on track for its 2027 entry into service, with Boeing reiterating that plan earlier this week as launch customer Lufthansa’s first production aircraft made its maiden flight.

While SIA’s first 777-9 took to the skies back in August 2025, that aircraft joined the test and certification programme and will be delivered to SIA at a later date, potentially after some later-built airframes.

The Lufthansa example that flew this week was the first to feature a complete passenger cabin interior rather than racks of test equipment, and the German airline’s CEO recently confirmed that delivery is expected in early 2027, for entry-into-service in the northern summer 2027 season (which kicks off on 28th March 2027).

Other major customers, including Emirates and Qatar Airways, may also sit ahead of SIA in the delivery queue, which could realistically push SIA’s first 777-9 deeper into 2027.

The silver lining though is that SIA’s Boeing 777-9 now likely won’t follow too far behind the retrofitted Airbus A350 LH and Airbus A350 ULR aircraft with the new First and Business Class products on board.

That’s relevant because the 777-9 is itself a long-awaited fleet renewal piece, set to replace Singapore Airlines’ ageing Boeing 777-300ERs, aircraft that aren’t scheduled to receive the latest cabin upgrades nor the faster Starlink Wi-Fi, despite remaining in the fleet into the 2030s.

SIA’s Airbus A350 cabin retrofit programme has hit its first delay since the airline announced it in November 2024, with the first refitted A350 Long Haul aircraft now entering service in Q1 2027, rather than Q2 2026. The airline cites industry-wide supply chain constraints and a certification delay on one of the new seats.

While the retrofit itself has held to schedule up to this point, the products it’s introducing have been a long time coming, having originally been due to debut on the Boeing 777-9 way back in 2021, before the much-delayed 777X programme prompted SIA to pivot to an A350 retrofit as the launch platform.

The A350 ULR fleet, which is set to introduce the all-new four-seat First Class section, may slip even further. Current schedule signals point to a Q2 2027 entry-into-service rather than the previously communicated Q1 2027, though SIA itself is not yet committing to a revised date.

For an airline whose primary long-haul Business Class product still dates back to 2013, this is a frustrating outcome, extending the wait before passengers can finally sample the first true step-change in SIA long-haul Business Class design in nearly 14 years.

Overall, while it’s bad news for SIA regulars looking forward to a 2026 Business Class debut, an early-to-mid 2027 entry-into-service still gives the carrier a reasonable runway to roll the new seats out across the A350 fleet in the coming years, not far out of step with the long-delayed arrival of its first Boeing 777-9s, which themselves will arrive with the same new products on board.
