How this map was built

Current fleet-linked numbered native map independently viewed. A350-900 Medium Haul 40J/263Y: exact Business 11/12/14–21ADFK; Economy rows 41–54 and 56–68 ABCDEGHJK, partial row 55 BCDEGHJ, row 69 BCDEGHJK and row 70 BCDEG. The Economy grid totals 14×9 + 7 + 13×9 + 8 + 5 = 263 seats. Marketing 263Y includes six native Extra Legroom positions, counted as 6N/257Y by SeatRecon; the complete summary is 40J/6N/257Y. The native Business console legend distinguishes left/right consoles; centre seats with consoles next to the aisle (examples 11D/F and 14D/F) have an adjustable centre divider, and seats with consoles away from the aisle are identified as wheelchair accessible. These product/accessibility facts do not imply extra comfort ratings. Published cabin product dimensions are specification evidence only; per-seat unshown hardware, per-tail assignment and future retrofit geometry are not certified. 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 Unverified prior storage flags are withdrawn.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. Native missing row70 right band is blank before the labelled galley after that row; no service caution is inferred through this uncalibrated gap.
