Air China Boeing 787-9 — mapa de assentos

Single three-class configuration flown by all 14 Air China Boeing 787-9s. PER-CABIN SEAT COUNTS ARE PRIMARY/PUBLISHED: Air China's own aircraft page (airchina.us Boeing 787 introduction) states 30 Business / 34 Premium Economy / 229 Economy = 293, and the neutral Wikipedia Air China fleet table corroborates 14x 787-9 in the same 30/34/229=293 layout. THE ROW GRID, CABIN BOUNDARIES, PARTIAL ROWS, DOORS, GALLEYS, LAVATORIES AND CLOSETS ARE READ FROM AIR CHINA'S OFFICIAL PUBLISHED 787-9 SEAT-MAP DIAGRAM (airchina.us B787-9EN.jpg): Business rows 11-15 in 2-2-2 (A C / D H / J L = 6-abreast, 5x6=30); Premium Economy rows 31-34 in 3-3-3 (A B C / D E H / J K L) with a partial bulkhead row 31 behind Door 2 (seats A,C,D,E,H,J,L = 7; B and K absent) plus full rows 32-34 (27) = 34; Economy in 3-3-3 sharing the same nine-abreast lettering. COUNT-VS-DIAGRAM RECONCILIATION (AUTHORING 5b): the published diagram's Economy seat glyphs sum to ~232 (full 3-3-3 rows 35-46 over the wing = 108; a centre-galley gap removing D E H at row 47 leaving A B C + J K L = 6; full rows 48-59 = 108; a tapered row 60 with A C / D E H / J L = 7; and a lone trailing centre triple D E H drawn at row 61 = 3). This exceeds the SAME page's explicitly stated 229 Economy / 293 total by exactly one 3-seat triple. Per numeric-over-image reconciliation the grid follows the airline's stated 229: Economy is modelled as rows 35-60 (35-46 full, row 47 centre-galley, 48-59 full, row 60 taper) = 229, and the diagram's trailing row-61 centre triple is treated as stylised over-draw and omitted. The Economy cabin therefore carries derived:true and layoutProvenance is 'mixed'; Business (30) and Premium Economy (34) reconcile exactly with the diagram and are not derived. DOORS: Door 1 before row 11, Door 2 before row 31 (Premium Economy bulkhead), Door 3 before row 47 (behind the wing, with a mid-cabin lavatory/galley bay after row 46 and a centreline galley at row 47), Door 4 aft after row 60. Wing spans roughly rows 31-46 (Economy rows 35-46 marked over_wing). DIMENSIONS ARE NEUTRAL-SOURCED (Wikipedia Air China), not airline-published: Business is the 'Capital Pavilion' Collins Parallel Diamond lie-flat (2-2-2), 6'4" (76 in) bed, 21 in width, ~79 in row pitch, 15-16 in touchscreen, Universal AC + USB-A (this specific Wikipedia sentence is tagged 'citation needed'); Premium Economy pitch 36-38 in / width 17.1-18 in; Economy pitch 31 in / width 17-18 in, AVOD seat-back IFE. windowAlignment is left 'unknown' for window seats (the diagram shows seat positions but not window mullions, and no 787 window grid exists, so windowGridType is omitted).
