Peta kursi American Airlines Boeing 787-9

American's new premium ('P') Boeing 787-9 Dreamliner, distinct from the legacy 787-9. Cabin split (51 Flagship Suite + 32 Premium Economy + 18 Main Cabin Extra + 143 Main Cabin = 244) is taken from the Wikipedia American Airlines fleet table (NEUTRAL); the 51/32 counts are additionally confirmed by American Airlines Newsroom (PRIMARY). ROW GRID IS DERIVED, not sourced: aa.com is bot-blocked (403) and no competitor seat-map site was consulted. Rows are derived from the stated abreast layouts (Flagship Suite 1-2-1, Premium Economy 2-3-2, Main Cabin 3-3-3) plus the published per-cabin counts. Derivations: Flagship Suite rows 1-13 (rows 1-12 full = 48, row 13 = 3 suites to reconcile 51, split into a forward cabin rows 1-9 and a rear mini-cabin rows 10-13); Premium Economy rows 15-19 (rows 15-18 full = 28, row 19 reduced to the two window pairs = 4 to reconcile 32); Main Cabin Extra rows 20-21 (2x9 = 18) modeled as the front extra-legroom section; Main Cabin rows 22-37 (rows 22-36 full = 135, last row 37 = 8 for fuselage taper, = 143). Row numbers, the single exit row (row 28 / Door 3), the over-wing band (rows 22-29), furniture positions, and bassinet positions are inferred and may not match the actual airframe. All seat DIMENSIONS (pitch/width/bed length) are unsourced estimates (unsourced:true) because American does not publish them on an accessible primary page; they are placeholders pending a citable source. Screen sizes are omitted for the same reason (Newsroom confirms Thales 4K QLED but not sizes).
