Singapore Airlines (SQ), which runs the longest non-stop flight in the world on the Airbus A350-900ULR, has announced the expansion of its all-new First-Class cabin on this very aircraft with Los Angeles International Airport (LAX) joining New York-JFK in offering the carrier’s latest flagship luxury experience, reported Mainly Miles.

Around the end of 2024, South China Morning Post had reported that this development reflects Singapore Airlines’ broader $1.1 billion programme to completely revamp its long-haul fleet with new premium cabins, including First and Business Class on ULR jets that serve some of the world’s longest non-stop routes.

Details of the New First-Class debut on A350-ULR
From 1 November 2026, Singapore Airlines will reassign one of its ultra-long-range Airbus A350-900ULRs to the Los Angeles (LAX) route to introduce the newly configured First-Class cabin, joining services to New York’s John F. Kennedy International Airport (JFK). Previously, the ultra-long-haul flights between Singapore and U.S. west coast lacked a true First-Class product, despite their extraordinary duration and premium demand.
The following table summarizes the revised fleet utilization and cabin changes for the A350 ULR line:
| Route | Previous Aircraft | New Aircraft (From Nov 2026) |
|---|---|---|
| SIN–LAX | Standard A350 Long Haul | A350-900ULR with First Class |
| SIN–JFK | A350-900ULR | A350-900ULR with new First Class |
| SIN–EWR | A350-900ULR | A350-900ULR |
| SIN–SFO | A350-900 | Standard A350 Long Haul |
Data from planespotters.net reveals that Singapore Airlines’ 65 Airbus A350-900s are 6.8 years old. The youngest of these is registered 9V-SMZ and is 6.3 years, while the oldest of these is registered 9V-SGA and is 7.5 years old.

Singapore’s A350-900ULR fleet and New Cabin Configuration
Singapore Airlines’ ultra-long-range Airbus A350-900ULR aircraft represent a bespoke variant of the A350 family, engineered for exceptionally long non-stop flights exceeding 15 hours. The retrofit entails the following cabin layout changes:
| Cabin Class | Before | After |
|---|---|---|
| First Class | — | 4 suites |
| Business Class | 67 | 70 seats |
| Premium Economy | 94 | 58 seats |
| Total Seats | 161 | 132 |

When it was first revealed that SQ would comprehensively refresh its Airbus A350 Long Haul and A350-900ULR fleets in November 2024, the carrier deliberately limited technical disclosures, opting instead to signal a broader strategic shift rather than reveal product specifics prematurely.

That restraint has continued into 2026. Singapore Airlines has indicated that a formal product unveiling will take place during a dedicated launch event in the first half of the year, at which point both the new Business Class seat and the First-Class suites—destined for the ultra-long-range aircraft—will be revealed in full.
The carrier said that all cabin classes would be equipped with:
“SIA’s next generation KrisWorld in-flight entertainment system (IFE), offering a more personalized interface and an expanded selection of entertainment and lifestyle content… The first retrofitted A350-900 long-haul aircraft is expected to enter service in the second quarter of 2026, while the first retrofitted A350-900ULR variant will follow in the first quarter of 2027. The entire programme is targeted for completion by the end of 2030”.

What is Known about the New First-Class Suites
While detailed specifications remain closely guarded, early visual material released by the airline offers some insight into the direction of the First-Class design. The product appears to prioritize enclosure, spatial separation, and visual refinement over sheer seat count.
Based on currently available information, the new First-Class cabin is expected to feature:
-
Fully enclosed suites fitted with angled privacy doors
-
A total of four suites per aircraft, likely arranged in a single-row 1-2-1 configuration
-
Window seats incorporating integrated blinds within the window shades

Business class’ Suite-style Privacy
Singapore Airlines has confirmed that the redesigned Business Class cabin will enter service ahead of First Class, debuting on Airbus A350 Long Haul aircraft from the second quarter of 2026.
Although artist impressions reveal limited detail, several layout characteristics are already apparent:
-
Alternating window-aligned and aisle-aligned seats in each row
-
A configuration similar to Singapore Airlines’ latest Regional Business Class
-
The potential for paired centre seats in alternating rows, enabling so-called “honeymoon” layouts that may convert into double beds for couples.
- Closing suite doors, offering enhanced privacy from the aisle.

Technology and Connectivity Upgrades Across both Cabins
Beyond physical seating, Singapore Airlines is expected to introduce a suite of technological enhancements across both premium cabins:
-
USB-C power outlets and wireless charging pads
-
Bluetooth audio connectivity for personal headphones
-
Larger, higher-resolution KrisWorld in-flight entertainment screens
In November 2025, Singapore Airlines unveiled its plans to install a Low Earth Orbit (LEO) satellite-based Wi-Fi system during the retrofit process. The system is widely expected to be powered by Starlink, offering substantially faster and more reliable internet connectivity on long-haul flights.
The Refit will be More than a Hardware Upgrade
Singapore Airlineswill have a comprehensive refresh encompassing multiple touchpoints across the premium travel experience.
In addition to new seating products, the upgrade programme will extend to:
-
Enhanced onboard dining concepts
-
Refreshed amenity kits and soft furnishings
-
Upgraded KrisWorld entertainment content and interfaces

Los Angeles Might Be the Launch City
According to Mainly Miles, if Singapore Airlines introduces its first refitted Airbus A350-900ULR on a limited basis, Los Angeles appears to be the most operationally efficient choice, as the Los Angeles service (SQ36/35) operates on a fixed three-day pattern—Wednesdays, Fridays, and Sundays—allowing a single dedicated aircraft to cover all rotations without drawing on operational reserves.
That simplicity matters when only one refitted aircraft is available.
Operational advantages of Los Angeles include:
-
A single aircraft can operate the entire weekly schedule
-
Predictable ground time in Singapore, including one full day off per week
-
Minimal disruption risk, with four remaining ULRs covering New York-area services and one spare available
-
Buffer time to resolve early cabin-service or technical teething issues
New York might Be operationally harder at first for a variety of reasons including:
-
Longer flight times reduce scheduling flexibility
-
Increased reliance on the standby aircraft
-
Higher exposure to winter irregular operations
-
Less tolerance for initial product issues
With only one aircraft modified, Los Angeles remains the cleaner, lower-risk option.

Possible A350 ULR First Class Deployment
| refitted aircraft in service | likely routes with new first class |
|---|---|
| 1 aircraft | Los Angeles – 3x weekly |
| 2 aircraft | Los Angeles – 3x weekly New York JFK – 3x weekly |
| 3 aircraft | Los Angeles – 3x weekly New York JFK – 6x weekly |
| 4 aircraft | Los Angeles – 3x weekly New York JFK – daily Newark – 2x weekly |
| 5 aircraft | Los Angeles – 3x weekly New York JFK – daily Newark – 4x weekly |
| 6 aircraft | Full new-cabin coverage on reduced ULR schedule |
| 7 aircraft | Full new-cabin coverage on regular ULR schedule |
Note: This projection by Mainly Miles is speculative and based on operational logic rather than airline confirmation.
