Air China Airbus A350-900 — mapa de assentos

Three-class Air China A350-900. Air China (aircraft-introduction page) and Airbus (2018 first-delivery press release) both publish the per-cabin counts: 32 Business / 24 Premium Economy / 256 Economy = 312 total; Wikipedia's fleet table lists 30 airframes in service at this single configuration. Air China does NOT publish a row grid or a seat map for the A350, so row numbering, column letters, cabin boundaries, door/exit positions, the over-wing span (rows 24-38) and the rear-fuselage taper (rows 47-48) are DERIVED from the published counts and standard A350-900 geometry (Business 1-2-1 rows 1-8 = 32; Premium Economy 2-4-2 rows 11-13 = 24; Economy 3-3-3 rows 20-46 = 243 plus a seven-abreast taper row 47 and a six-abreast last row 48 to reach 256). Every cabin carries derived:true and windowAlignment is left "unknown" for window seats because a derived grid cannot prove a real window lines up (no A350 window grid exists, so windowGridType is omitted). Business hardware differs by airframe: Wikipedia states newer A350s carry Recaro CL6720 seats and older A350s carry reverse-herringbone Collins Aerospace Super-Diamond seats — BOTH are 1-2-1, lie-flat (6'4" bed), 21" wide with direct aisle access and 18" screens, so the passenger-facing geometry, counts and ratings are identical and this is modelled as one configuration (one business seat type covering both). Seat dimensions (Business 21" width / 6'4" bed; Premium Economy 38.5-39" pitch, 18.5" width; Economy 31" pitch, 17-18" width) come from the Air China article on Wikipedia, which flags some Business-cabin specifics "citation needed" (see source caveat).
