Sơ đồ ghế British Airways Boeing 777-200ER

British Airways Heathrow 777-200ER three-class configuration (no First) with Club Suite. Seat arrangement, cabin zones (Club Suite — the map labels the business zone 'Club World' but the hardware drawn is the reverse-herringbone Club Suite with privacy doors — 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 raster 'boeing-777-200ER-full-seatmap' (PRIMARY, layoutProvenance published_map). Counts read from the map: 48 Club Suite = 28 forward (rows 1-7, 1-2-1) + 20 rear (rows 10-14, 1-2-1); 40 World Traveller Plus (rows 15-19, 2-4-2); 184 World Traveller = 50 forward (rows 25-29, full 3-4-3) + 134 rear (row 30 centre D/E/F/G only, rows 31-40 full ten-abreast, rows 41-43 taper to eight with columns C/H dropped, row 44 = D/E/F/G/J/K with a monument in place of 44A/44B). These counts exactly match the Wikipedia British Airways fleet table (NEUTRAL) row 48/40/184 = 272, which shares the fleet table's 'Heathrow configuration with new interior configuration with Club Suites' annotation — this is a CURRENT Club Suite layout, not the retired pre-Club-Suite fit. Four door pairs (before row 1, before row 10, before row 30, aft) match 777-200 geometry. Wikipedia lists 43 777-200ER airframes across all configurations; the split between this config and the 237-seat with-First config is not published on the cited sources, so fleetCount is omitted. BA labels the map 'representative'. BA does not publish pitch/width/bed or screen sizes, so all seat-type dimensions and screens are unsourced estimates (unsourced:true). windowAlignment is left 'unknown' on window seats because the schematic map does not prove real window alignment; no engineering window grid exists for the 777 so windowGridType is omitted. Door numbering and furniture row-alignment are interpretations of the schematic monuments. aircraft.variant follows BA's own map title ('777-200ER').
