Sơ đồ chỗ ngồi American Airlines Boeing 777-300ER

Legacy four-cabin American Airlines 777-300ER, being converted away from under 'Project Olympus'. PER-CABIN COUNTS ARE SOURCED: total 304 seats and 20 airframes (18 owned + 2 leased) are stated in the AAG FY2025 10-K (PRIMARY, aircraft table, '304' average seats / '20' total); the cabin split 8 Flagship First / 52 Flagship Business / 28 Premium Economy / 28 Main Cabin Extra / 188 Main Cabin = 304 is from the Wikipedia American Airlines fleet table (NEUTRAL). The 10-K also states American 'began the reconfiguration of our Boeing 777-300ER fleet to add seats' in 2025 (the 330-seat retrofit). THE ROW GRID IS DERIVED, NOT A PLACARD SCAN: aa.com hard-403s (bot-blocked) and competitor seat-map sites are prohibited sources. Abreast layouts (Flagship First 1-2-1, Flagship Business 1-2-1 reverse herringbone, Premium Economy 2-4-2, Main Cabin 3-4-3) plus per-cabin counts drive the grid. Derivations: Flagship First rows 1-2 (2x4=8); Flagship Business rows 3-15 (13x4=52); Premium Economy rows 20-23 (rows 20-22 full 2-4-2 = 24, row 23 reduced to the center four = 4, to reconcile 28); Main Cabin rows 30-51 (216 seats) with Main Cabin Extra (28) modeled as the forward bulkhead row 30 (10) plus the two Door-3 exit rows 41 (10) and 42 (8, center pair ceded to a mid-cabin galley) = 28, and standard Main Cabin (188) as rows 31-40 (100), 43-50 (80) and the rear-taper last row 51 (8, window pairs dropped) = 188. Row numbers, exit-row placement, over-wing band (rows 34-44), furniture, bassinet and galley positions, and the partial rows (23, 42, 51) are inferred to reproduce the published per-cabin totals and abreast layouts and may not match any individual airframe. AA additionally sells exit rows elsewhere as Main Cabin Extra on the real aircraft; the derived grid consolidates the sourced count of 28 MCE seats into rows 30/41/42. 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page; screen sizes are omitted for the same reason (legacy 777-300ER has Panasonic seatback IFE in all cabins, sizes unpublished in the cited sources).
