3 versions · 8.7 to 9.6 out of 10 · 11 tracked routes
CabinScore has measured 3 physically different business-class cabins that Singapore Airlines flies on the A350-900, rated 8.7/10 to 9.6/10 — and booking sites sell every one of them as the same “Business” fare.
The Versions, Ranked
Top routes are the ones we most often observe each cabin flying, from the flight history we track, resolved to individual registrations; the percentage is how often a flight on that route is this cabin. They describe our tracked network, not Singapore Airlines's whole A350-900 fleet — and a version we haven't measured would not appear here at all.
How to Tell Which One You're Getting
Business Class9.6/10
Lie-flat Business Class seat on Singapore Airlines' long-haul Airbus A350-900 sub-fleet, configured 1-2-1 across two cabin sections with 42 seats total (a smaller forward cabin plus a rear cabin). Same 2013 wide flat-bed product as the A350-900 ULR — distinct from the narrower 2018 Stelia Symphony seat used on the regional A350-900 sub-fleet and the 787-10. The seat converts into a flat bed by flipping the seat back forward to form the bed surface; very wide seat (~71 cm / 28 in) with an offset, angled footwell in most rows, and a larger full-width foot bench at bulkhead rows. Every seat has direct aisle access. Long-haul aircraft also carry a Premium Economy cabin, distinguishing them from the regional sub-fleet (which has no PE).
- 1-2-1 layout with very wide seat shells — distinctly broader than the regional A350-900 / 787-10 Symphony seat
- Window seats angle slightly toward the windows; offset/angled footwell in most rows
- Bulkhead rows have a noticeably larger full-width foot bench/ottoman
- Two J cabin sections (smaller forward + rear) — fewer rows than the 67-seat ULR's two cabins
- Aircraft has a Premium Economy cabin behind J — regional A350-900s do not
Business Class9.6/10
Lie-flat Business Class seat on Singapore Airlines' Airbus A350-900 ULR (ultra long range) configured 1-2-1 across two cabins (67 seats total), designed to convert into a flat bed by flipping/folding the seat back forward into a bed surface; notably very wide seat with an offset footwell in most rows, and larger footwell/bench in bulkhead rows.
- Look for 1-2-1 layout with very wide seat shells; window seats angle slightly toward windows; most rows have an offset/angled footwell; bulkhead rows have a noticeably larger, full-width foot bench/ottoman area
- 67 J seats across two cabin sections — distinctly larger J than the long-haul (42) or regional (40) A350-900 sub-fleets
- ULR airframes have no Premium Economy and no Y — entire aircraft is J + PE-equivalent only
Regional Business Class8.7/10
Singapore Airlines' regional A350-900 sub-fleet uses the Stelia Aerospace Symphony seat in a staggered 1-2-1 forward-facing layout — the same seat as the 787-10 fleet, not the wider 2013 flat-bed found on the long-haul/ULR A350-900 cabins. Every seat has direct aisle access. The fully lie-flat bed measures 76 inches (193 cm) in length and 20 inches (51 cm) at seat position, widening to approximately 26 inches with the armrests retracted. Alternating rows create \"honeymoon\" centre-pair seats that sit close together, ideal for couples, while the remaining rows have wider centre separation. Window seats wrap in a tall privacy shell along the fuselage side, creating a cocoon effect. The cabin is equipped with an 18-inch Panasonic eX3 HD touchscreen, adjustable dividers in the centre section, three charging ports, an enclosed storage compartment, and an extendable mirror. Wi-Fi is complimentary in Business Class.
- Staggered 1-2-1 with visible alternating honeymoon/separated row pattern
- 40 J seats in a single cabin (vs 67 on ULR or 42 on long-haul A350-900s)
- Tall cream-and-grey privacy shell curves around the window-seat shoulder
- Forward-facing flat-bed — not the wide flip-over seat used on Singapore's long-haul A350-900s
- 18-inch touchscreen on a rotating arm; extendable mirror in seat shell
