Seat assessment

Ratings reviewed against the cited evidence. Details without sufficient evidence, including unknown window alignment, remain unverified.

Historical November 2024 announcement: 42J/24W/192Y long-haul retrofit. The then-announced launch dates are historical targets, not a current service confirmation; no successor grid is generated without an exact published map.

How this map was built

Current fleet-linked numbered native map independently viewed. A350-900 Long Haul 42J/24W/187Y: exact partial rows 18DF,46ABCHJK,47BCDEGHJ,62DEG. Published cabin product dimensions are specification evidence only; per-seat unshown hardware, per-tail assignment and future retrofit geometry are not certified. Fleet counts retain their historical dated as-of values. The November 2024 retrofit announcement is historical: no exact successor map is linked by the current A350 fleet page, so announced 258-seat long-haul/132-seat ULR grids are not invented. October 6 methodology review: every seat evaluated within its own sold cabin. Sourced physical drawbacks cap at Be Aware; qualified service/bassinet cautions also prevent an unqualified upgrade. Extra Legroom is physical leg-space evidence, not a fee-based promotion. Exit eligibility, Forward Zone fees and ordinary positions remain neutral. All unmarked outboard window alignment is unknown; engineering overlays are disabled. No fixed-armrest, tray mechanism, reduced width, cold-air, recline exception or permanent storage loss is inferred from generic bulkhead/exit position. Unverified prior storage flags are withdrawn. Native furniture is schematic; no precise clearance/noise claim, no automatic Avoid from correlated service cautions. Product dimensions and historical retrofit announcements do not establish an unshown successor layout. Airline marketing counts all 187 Economy seats together. SeatRecon separately identifies the six published Extra Legroom Economy positions as N, so its computed cabin summary is 42J/24W/6N/181Y; 6N + 181Y = the same 187 Economy seats, not an extra cabin or missing seats. Native45DEG are separated from centre lavatories after46 by the blank missing46DEG band; no adjacency is inferred across this uncalibrated gap. Outboard46 seats directly preceding lavatories and61 outboard seats preceding labelled monuments filling missing62 outboard blocks retain their qualified cautions.
