Sơ đồ chỗ ngồi American Airlines Boeing 777-200ER

Single standard four-cabin configuration of American's Boeing 777-200ER (no Flagship First — that cabin exists only on the 777-300ER). PER-CABIN COUNTS ARE SOURCED: the AAG FY2025 10-K (PRIMARY, aircraft table) lists the 777-200ER at 273 average seats across 47 airframes (44 owned + 3 leased); the cabin split 37 Flagship Business / 24 Premium Economy / 66 Main Cabin Extra / 146 Main Cabin = 273 is from the Wikipedia American Airlines fleet table (NEUTRAL). 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 Business 1-2-1 reverse herringbone, Premium Economy 2-4-2, Main Cabin / Main Cabin Extra 3-4-3) plus the per-cabin counts drive the grid. Derivations: Flagship Business rows 1-9 (9x4=36) plus a single leftover seat 10A (the sourced count of 37 is odd for a 1-2-1 cabin, so one seat is modeled as a partial last row against the galley); Premium Economy rows 20-22 (3x8=24); Main Cabin Extra rows 30-36 (rows 30-35 full 3-4-3 = 60, row 36 reduced to the six outboard seats with the center block ceded to a mid-cabin galley = 6, total 66) modeled as an extra-legroom ZONE inside the single Main Cabin per house style; standard Main Cabin rows 37-51 (rows 37-43 and 45-51 full = 140, row 44 reduced to six outboard seats at the Door-3 galley = 6, total 146). Row numbers, exit-door placement (Doors 1/2/3/4 at rows 1/20/40/51), over-wing band (rows 34-44), galley/lavatory and bassinet positions and the three partial rows (10, 36, 44) are inferred to reproduce the published per-cabin totals and abreast layouts and may not match any individual airframe. 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screen sizes are omitted for the same reason (the retrofitted 777-200ER has Panasonic seatback IFE in all cabins, sizes unpublished in the cited sources). American has publicly signalled a future premium retrofit of the maturing 777-200 fleet, but no reconfiguration of the 777-200ER is in passenger service and the FY2025 10-K describes only the separate 777-300ER reconfiguration; this config is therefore modeled as the current active layout.
