Singapore Airlines A350-900ULR Seat Selection Guide (2025)
Singapore Airlines' Airbus A350-900ULR is designed exclusively for the world's longest non-stop flights, including Singapore to New York and Singapore to Los Angeles. The aircraft is configured with only two cabins:
- Business Class (1-2-1, 67 seats)
- Premium Economy (2-4-2 and 1-4-1, 94 seats)
There is no Economy cabin on the A350-900ULR.
This guide explains the best seats, seats to avoid, cabin quirks, and how the ULR differs from the standard A350-900 Long-Haul version.
Important: Singapore Airlines operates three distinct A350 configurations:
- A350-900 Long-Haul (Business + Premium Economy + Economy)
- A350-900 ULR (this guide – Business + Premium Economy only)
- A350-900 Medium-Haul (Business + Economy, no Premium Economy)
If you see an A350 with an Economy cabin, you are not on the ULR version.
⚠️ Major refit arriving Q1 2027: Singapore Airlines is adding a 4-seat First Class cabin and replacing Business Class with new closed-door suites on all A350-900ULR aircraft. Premium Economy drops from 94 to 58 seats. The current layout described in this guide will be phased out through 2030. Read our full breakdown of the refit →
1. Quick Verdict
Business Class:
The best seats are true window seats (A/K) located in the mid-cabin of either Business section. These offer maximum privacy for ultra-long flights and reduced aisle disturbance. Couples should select middle D/F seats in the same zone.
Premium Economy:
Choose 31A/C and 31H/K for bulkhead legroom, or aim for the "solo" window seats toward the rear of the Premium Economy cabin if you're travelling alone. Window pairs in Rows 32–37 are ideal for couples.
There is no Economy cabin on this aircraft.

ULR Identification Tip:
If your seat map shows no Economy cabin and Premium Economy stretching from the low 30s to the 40s, you are on the A350-900ULR. If Economy appears, refer to the A350-900 Long-Haul or A350-900 Medium-Haul guides instead.
4. Business Class Seat Recommendations (2013 Long-Haul Seat)
The A350-900ULR uses the same 2013 long-haul seat found on the A350-900 Long-Haul and selected 777-300ERs. All seats convert into a fully flat bed by flipping over the seat shell.
There are two Business cabins, each offering its own advantages.
| Category | Seats | Reason |
|---|---|---|
| Best Overall | 14A/K, 15A/K, 20A/K, 21A/K | True window seats in the quietest mid-cabin zones |
| Best Solo | Any true window A/K away from cabin ends | Maximum privacy and limited aisle exposure |
| Best for Couples | 14D/F–17D/F or 20D/F–24D/F | Middle seats close together with shared divider |
| Best for Sleeping | Window seats in mid-cabin areas | Lower foot traffic and stable ride over the wing |
| Fastest Exit | 10D/F, 11A/K | Very quick disembarkation; more galley and curtain noise |
| Seats to Avoid | First row of each Business cabin | Increased noise from curtains, galleys and boarding activity |
| Consider Carefully | Aisle-side window seats | Seat is next to aisle; reduced privacy vs true windows |
5. Premium Economy Seat Recommendations
Premium Economy on the ULR is very large compared to the Long-Haul version. It is arranged in a combination of 2-4-2 and 1-4-1, creating a mixture of standard pairs and highly sought-after solo seats.
| Category | Seats | Reason |
|---|---|---|
| Best Overall | 31A/C & 31H/K | Bulkhead legroom; ideal for tall travellers |
| Best for Couples | Rows 32–37 A/C and H/K | Window pairs with good privacy and distance from the galleys |
| Best for Solo Travellers | Solo window seats in rear PE (around Rows 40–41) | True single seats with no neighbour directly beside you |
| Best for Working | A or K seats in Rows 31–35 | Easy access to aisle and service; stable mid-cabin area |
| Quietest Area | Rows 34–37 | Middle of the PE cabin, away from both curtain and galley |
| Seats to Avoid | Last rows of PE | Close to rear galley and toilets |
| Consider Carefully | Centre block (D/E/F/G) | Fine for families, less ideal for solo passengers on 17–18-hour flights |
6. Known Issues & Cabin Quirks
| Issue | Details |
|---|---|
| Narrower aisles in Business | The ULR layout uses slightly narrower aisles due to weight-optimised cabin design |
| Smaller footwells vs 777-300ER | Some seats have marginally tighter foot space; best avoided by choosing true windows |
| Two Business cabins | Front cabin is best for fast exit; rear cabin offers better privacy |
| Large Premium Economy cabin | 94 seats total; larger and less intimate than the Long-Haul A350's 24-seat PE |
| Solo PE seats | Highly desirable single-seat layout at rear of PE |
| No Economy cabin | All passengers are seated in Business or Premium Economy only |
7. Best Seats Summary
| Cabin | Best Seats | Why | Avoid |
|---|---|---|---|
| Business | True window seats in mid-cabin (14A/K, 15A/K, 20A/K, 21A/K) | Most private and quiet | First rows of each cabin; aisle-side window seats |
| Premium Economy | 31A/C & 31H/K; mid-cabin windows; rear solo seats | Bulkhead legroom, quiet window pairs, single-seat privacy | Last rows near galley; centre block seats for solo travellers |
