Sơ đồ chỗ ngồi Air China Boeing 777-300ER

Three-class international Air China Boeing 777-300ER. PER-CABIN COUNTS ARE SOURCED: the Wikipedia Air China fleet table (neutral backbone) lists 28 777-300ERs in two configs, one being 8 First / 42 Business / 261 Economy = 311; Air China's official 777 aircraft-introduction page (primary) corroborates that the 777 carries First, Business and Economy cabins. CABIN PRODUCTS ARE SOURCED (Wikipedia prose citing airchina.us): First = "Forbidden Pavilion" Safran/Zodiac Venus enclosed suites (1-2-1, 82-83 in pitch, 23 in width, 23 in AVOD); Business = "Capital Pavilion" Collins Parallel Diamond (2-2-2, 6'4" flat bed, 21 in width, 15-16 in screen); Economy ~31 in pitch, 17-18 in width, universal AC + USB-A. LAYOUT DERIVED_FROM_COUNTS: no published seat map was fetched (airchina.us seat maps are image/JS-only), so the row grid, door/exit positions and monuments are structural reconstructions from the published per-cabin counts + standard 777-300ER geometry; every cabin carries derived:true. DERIVATIONS: First 1-2-1 rows 1-2 (2x4=8); Business 2-2-2 rows 10-16 (7x6=42); Economy 3-3-3 (9-abreast, consistent with Air China's 777 economy) rows 30-58 (29x9=261) with bulkhead row 30, two over-wing exit rows 45-46, a limited-recline row 44 ahead of them, and a galley-backed last row 58. Economy width set to 18 in (upper end of the published 17-18 in range) for 9-abreast; economy recline (5 in) and screen size are unsourced estimates flagged as such. windowAlignment is "unknown" on window seats because the grid is derived (no 777 window grid). Per-config airframe count within the 28-aircraft fleet is not published.
