American Airlines Airbus A321neo — mapa de assentos — 190 assentos

American's ex-Alaska Airlines A321neo sub-fleet (10 aircraft per Wikipedia) — early A321neo airframes originally operated by Virgin America / Alaska, acquired by American and reconfigured. These frames PRE-DATE Airbus Cabin Flex (ACF): they retain the classic four-door-pair arrangement (8 exits: Doors 1/2/3/4) rather than the two overwing exit pairs of the standard 196-seat config, which is why their capacity is capped lower at 190 seats. TOTAL A321neo fleet 84 (as of 2025-12-31) is from American Airlines Group's FY2025 SEC Form 10-K; the 74/10 split into the standard aa-321n-196 config and this 190-seat config is from Wikipedia's American Airlines fleet table (neutral); the 74+10 total and the 20/35 First+MCE columns give a 195-seat weighted average that reconciles with the 10-K. PER-CABIN SPLIT 20 First / 35 Main Cabin Extra / 135 Main Cabin = 190 is Wikipedia's tabulation; Wikipedia shares the First (20) and Main Cabin Extra (35) cells between the two configs, so the internal MCE/Main boundary for THIS config is especially uncertain and is treated as derived. Main Cabin Extra is modeled as a ZONE inside the single Main Cabin per AUTHORING §6 (seatType aa-mce, canonicalTier extra_legroom_economy). ROW GRID IS DERIVED. Derivation follows the classic (non-ACF) A321 door geometry: First 2-2 (A/C/D/F) rows 1-5 = 20; forward galley/lav divider (row 6 gap); Main Cabin 3-3 rows 7-35. MCE zone = forward rows 7-10 plus the Door 2 exit row 11 (29) and the Door 3 exit row 23 (6); standard Main fills the rest (135). Because 35 and 135 are not clean multiples of six, two rows are modeled short: the Door 3 exit row 23 with 5 seats (a seat lost at the door) and the rearmost row 35 with 3 seats (rear galley/lav taper); exact partial-row placement, MCE and exit-row placement, over-wing range and rear-monument positions are derived and may differ from the physical aircraft. aircraft.windowGridType is set to 'a321neo' per the assignment directive, but note that grid encodes the ACF (overwing-exit) arrangement, which does NOT match this non-ACF airframe; it is a nominal binding only and all window alignment is left 'unknown'. American does not publish A321neo pitch/width in any citable source, so all pitch/width values are approximate/unsourced. This 190-seat sub-fleet is being progressively cabin-refreshed; whether it is harmonized to the 196 ACF standard is not confirmed in a permitted source, so no retrofit link is asserted.
