British Airways Boeing 777-200 — rozkład miejsc — 237 foteli

British Airways Heathrow 777-200ER four-class configuration with First and Club Suite. Seat arrangement, cabin zones (First; 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-777-200-inc-first-full-seatmap' (PRIMARY, layoutProvenance published_map). Counts read from the map: 8 First (rows 1-2, 1-2-1); 49 Club Suite = 13 in the forward cabin (rows 5-7 full 1-2-1 plus a lone rear window suite 8K) + 36 in the rear cabin (rows 9-17, 1-2-1) — the odd 49 resolves visually as the asymmetric 8K; 40 World Traveller Plus (rows 20-24, 2-4-2); 140 World Traveller (3-4-3: row 25 centre D/E/F/G only, rows 26-35 full ten-abreast, rows 36-39 taper to eight with columns C/H dropped, row 40 centre D/E/F/G only). Four door pairs (before row 1, before row 9, before row 25, aft) match 777-200 geometry. CONFLICT NOTE: the Wikipedia British Airways fleet table (NEUTRAL) lists this Heathrow Club Suite config as 8F/49J/40W/138Y = 235; the published BA map enumerates 140 World Traveller seats = 237 total. The airline's own published map is retained as authoritative for the layout and the Wikipedia figure is recorded on that source's caveat — no third number is invented. Wikipedia lists 43 777-200ER airframes across all configurations; the split between this config and the 272-seat 3-class Club Suite config is not published on the cited sources, so fleetCount is omitted. BA labels the map 'representative' (config.representative true) — real per-flight layouts appear in Manage My Booking and per-tail variations exist (aviation press references 77L/77M subfleet codes for the with-First fleet; BA publishes a single 'with First' map so a single instance is modelled). 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 are 777-200ER airframes; aircraft.variant is set to '777-200' following BA's own map title ('777-200 with First').
