Sơ đồ chỗ ngồi American Airlines Boeing 787-9

Legacy three-cabin American Airlines Boeing 787-9 (Flagship Business, not the new enclosed Flagship Suite). This is a SEPARATE, PARALLEL subfleet from the premium 'P' aircraft modeled in aa-789p-flagship-suite.json: no cited source describes any conversion of these legacy 787-9 airframes into the 244-seat 787-9P, and American Airlines Newsroom (PRIMARY) positions the 787-9P as its 'new premium' / 'newest premium aircraft' — i.e. new deliveries (11 in the fleet) alongside these 22 legacy frames, not a retrofit of them. Both configs therefore stay 'active' with no supersededBy/replaces link. PER-CABIN COUNTS ARE SOURCED (NEUTRAL): the Wikipedia American Airlines fleet table lists this 787-9 subfleet as 22 aircraft, 30 Business (Flagship Business) / 21 Premium Economy / 27 Main Cabin Extra / 207 Main Cabin = 285. The AAG FY2025 10-K (PRIMARY) confirms American operates the 787-9 but its aircraft table shows only a BLENDED AVERAGE of 271 seats across BOTH 787-9 subfleets (legacy 285 + 787-9P 244) — that 271 is NOT the legacy per-cabin figure and is not used for the grid. The 787-9P launch press release corroborates the split indirectly (51 Flagship Suites 'up from' this cabin's business count and 32 Premium Economy 'up ~52%' from 21). THE ROW GRID IS DERIVED, NOT A PLACARD SCAN: aa.com hard-403s (bot-blocked) and competitor seat-map sites are prohibited. Abreast layouts (Flagship Business 1-2-1 reverse herringbone, Premium Economy 2-3-2, Main Cabin 3-3-3) plus the sourced per-cabin counts drive the grid. Derivations: Flagship Business rows 1-8 (rows 1-7 full 1-2-1 = 28, row 8 reduced to the center pair D/G = 2, to reconcile 30); Premium Economy rows 10-12 (3 full 2-3-2 rows = 21); Main Cabin rows 20-45 (26 full 3-3-3 rows = 234), with Main Cabin Extra (27) modeled as the forward bulkhead row 20 (9) plus the two Door-3 exit rows 31 (9) and 32 (9) = 27, and standard Main Cabin (207) as rows 21-30 (90) and 33-45 (117). Row numbers, the exit-row placement (Door 3 at rows 31-32), the over-wing band (rows 20-30), furniture, galley and bassinet positions, the partial business row 8 and the reduced-recline last row 45 are INFERRED to reproduce the published per-cabin totals and abreast layouts and may not match any individual airframe. AA sells Main Cabin Extra as scattered front/exit rows on the real aircraft; the derived grid consolidates the sourced count of 27 MCE seats into rows 20/31/32. ALL SEAT DIMENSIONS (pitch/width/bed length) are unsourced estimates (unsourced:true) — American does not publish them on an accessible primary page; screen sizes are omitted for the same reason (the legacy 787-9 has Panasonic seatback IFE in all cabins, sizes unpublished in the cited sources).
