Sơ đồ chỗ ngồi British Airways Boeing 787-9

British Airways 787-9 legacy layout with the 2014-era 'yin-yang' Club World business cabin (forward- and rear-facing lie-flat seats alternate, so alternate seats face aft — facing:'aft'). Seat arrangement, cabin zones (First; Club World; World Traveller Plus; World Traveller), exits, galleys, lavatories (incl. wheelchair-accessible) and carry-cot positions are READ row-by-row from British Airways' official Scene7 representative seat-map image 'boeing-787-9-full-seatmap' (PRIMARY, layoutProvenance published_map). Per-cabin counts read from the map: 8 First (rows 1-2, 1-2-1); 42 Club World = 14 forward (rows 6-7, 2-3-2) + 28 rear (rows 10-13, 2-3-2), six rows of seven; 39 World Traveller Plus (rows 16-21, 2-3-2; rows 16-20 full seven-abreast, row 21 window pairs A/B/J/K only where the centre is the mid-cabin lavatory/galley); 127 World Traveller (rows 30-44, 3-3-3; rows 30-42 full nine-abreast = 117, row 43 tapers to seven B/C/D/E/F/H/J, row 44 centre D/E/F only). Totals cross-checked against the Wikipedia British Airways fleet table (NEUTRAL): 787-9 fleet of 18, with the older 'Club World' configuration listed as 8/42/39/127 = 216. Club World is a 2-3-2 yin-yang lie-flat: window seats (A/K) face forward, the centre-trio middle seat (E) faces forward, and the aisle/centre seats (B/D/F/J) face aft. Recorded as retrofit_source because BA is replacing Club World with the reverse-herringbone Club Suite (config ba-789-clubsuite); both configs coexist while the retrofit runs through 2026-27 and the 18-airframe fleet split is not published on the cited sources. BA labels the map 'representative'. BA does not publish pitch/width/bed or screen sizes, so all seat-type dimensions and screen sizes are unsourced estimates. windowAlignment is left 'unknown' on window seats because the schematic map does not prove real window alignment; no engineering window grid exists for the 787-9 so windowGridType is omitted. Door numbering and furniture row-alignment are interpretations of the schematic monuments.
