Sơ đồ chỗ ngồi Singapore Airlines Airbus A350-900

Singapore Airlines' current fleet page lists the 303-seat Medium Haul configuration and links the official map transcribed here; the 2018 entry-into-service release independently states 40 Business in 1-2-1 and 263 Economy in 3-3-3. Business is 40 seats in rows 11, 12 and 14-21, all four-abreast, split by the Door 2 monument after row 18. The official map's alternating console-left/console-right glyphs are assigned seat-by-seat; middle seats with consoles by the aisle have an adjustable centre divider, and console-away-from-aisle seats are wheelchair accessible, but the schema has no per-seat accessibility field, so those map facts remain in notes. Economy is 263 seats: rows 41-54 full (126), partial row 55 with seven seats, row 56 full (9), rows 57-68 full (108), partial row 69 with eight seats, and partial row 70 with five seats (126 + 7 + 9 + 108 + 8 + 5 = 263). Six Economy positions are coloured Extra Legroom (55B/55C/55H/55J and 56A/56K), so the computed SeatLink summary is 40J/6N/257Y while SIA's marketing count remains 40J/263Y. Forward Zone is rows 41-47. All window positions remain unknown because the schematic is not to scale and there is no A350 engineering window grid in the repository.
