Mapa de asientos del Airbus A321neo de American Airlines

American's standard (Airbus Cabin Flex, ACF) A321neo — the majority sub-fleet (74 aircraft per Wikipedia). TOTAL 84 A321neos (49 owned / 35 leased, 195-seat average) as of 2025-12-31 are published in American Airlines Group's FY2025 SEC Form 10-K; the 84 splits into this 196-seat config (74 aircraft) and the ex-Alaska 190-seat config aa-321n-190 (10 aircraft) per Wikipedia's American Airlines fleet table (neutral), whose 74+10 total and 20/35 First+MCE split give a weighted 195-seat average that reconciles with the 10-K. PER-CABIN SPLIT: this file uses Wikipedia's citable split 20 First / 35 Main Cabin Extra / 141 Main Cabin = 196. The generation brief and some third-party seat maps instead cite 47 Main Cabin Extra / 129 Main Cabin; that split could not be corroborated in any permitted primary/neutral source (aa.com hard-403s bots and competitor seat-map sites are prohibited), so the archived Wikipedia figures are used and the exact Main Cabin Extra / Main Cabin boundary is treated as uncertain. Main Cabin Extra is American's extra-legroom economy PRODUCT, not a physically contiguous cabin (forward rows plus the exit rows, sold at a fee), so per AUTHORING §6 it is modeled as a ZONE inside the single Main Cabin, with MCE seats carrying seatType aa-mce (canonicalTier extra_legroom_economy). ROW GRID IS DERIVED, not a placard scan. Derivation: First 2-2 (A/C/D/F) rows 1-5 = 20; a forward galley/lavatory class divider occupies the unnumbered gap (row 6); Main Cabin 3-3 rows 7-36. MCE zone = forward rows 7-10 (24) + the two ACF overwing exit rows 15-16 (11); standard Main fills the remainder (141). Because 35 and 141 are not clean multiples of six, two rows are modeled short to hit the exact counts: the aft overwing exit row 16 is modeled with 5 seats (a seat lost at the exit) and the rearmost row 36 with 3 seats (rear galley/lavatory taper); exact partial-row placement, MCE row placement, exit-row placement, over-wing range and rear-monument positions are derived and may differ from the physical aircraft. The two ACF Type III+ overwing exits (rows 15-16) follow data/window-grids/a321neo.json; the ACF aft-of-wing Door 3 is not separately modeled as an exit row, consistent with the sister Delta ACF instance dl-321n-3ne. windowAlignment left 'unknown' on all window seats (derived grid). American does not publish A321neo pitch/width in any citable source, so all pitch/width values are flagged approximate/unsourced.
