Mapa de asientos del Airbus A321XLR de American Airlines

American's Airbus A321XLR, the first A321XLR operated by a U.S. airline; entered revenue service 2025-12-18 on the inaugural JFK-LAX transcontinental flight (American Airlines Newsroom, PRIMARY). CABIN SPLIT (20 Flagship Suite + 12 Premium Economy + 123 Main Cabin = 155) is stated by American's Newsroom (PRIMARY) and matched by the Wikipedia American Airlines fleet table (NEUTRAL), which further splits the 123 Main Cabin into 12 Main Cabin Extra (Y+) and 111 standard Main Cabin (Y), i.e. F-/J20/W12/Y+12/Y111/Total 155. American's FY2025 10-K (PRIMARY) independently reports the A321XLR at an average of 155 seats (2 aircraft, 0.1 years average age, as of 2025-12-31), corroborating both the seat total and that the type is in revenue service. FLEET COUNT: Wikipedia's fleet table (as of June 2026) shows 5 A321XLR in service and 35 on order; the FY2025 10-K showed 2 as of 2025-12-31 during the ramp. Main Cabin Extra is American's extra-legroom economy PRODUCT, modeled per AUTHORING section 6 as a ZONE inside the single Main Cabin (seatType aa-x-mce, canonicalTier extra_legroom_economy), not a separate cabin. ROW GRID IS DERIVED, not a placard scan (aa.com is bot-blocked; news.aa.com hard-403s direct fetches; competitor seat-map sites are prohibited). Derivation from the published abreast layouts + counts: Flagship Suite lie-flat 1-1 (columns A/F, direct aisle access) rows 1-10 = 20; Premium Economy 2-2 (columns A/C/D/F, no middle) rows 11-13 = 12; Main Cabin 3-3 rows 14-34 = 123. Within Main Cabin the 12 Main Cabin Extra seats are modeled as the two overwing exit rows (20-21 = 12), which structurally carry extra legroom; the remaining 111 are standard Main Cabin (18 full rows + a 3-seat rear partial row 34 to reconcile 123 exactly). ROW NUMBERS, the exact rows American designates as Main Cabin Extra, the overwing exit-row placement (rows 20-21), the wing band (rows 20-27), the rear partial row, and all furniture/monument positions are INFERRED and may not match the actual airframe. American does not publish A321XLR per-seat pitch/width/bed dimensions in any accessible citable source, so all dimensions are approximate/unsourced; Flagship Suite recline is modeled lie_flat. windowAlignment left 'unknown' on all window seats (derived grid). aircraft.windowGridType='a321neo' is bound because the A321XLR shares the A321neo fuselage length (44.51 m, verified via Wikipedia) and Airbus Cabin Flex door geometry; the A321neo grid carries no structural window blanks, so scripts/window-alignment.js --apply writes nothing and every window seat stays 'unknown'.
