Sơ đồ chỗ ngồi American Airlines Airbus A321ceo

American's premium three-cabin transcontinental A321-200 ('A321T'), historically flown on JFK-LAX/SFO — the only American narrowbody with lie-flat First and Business. STATUS: retrofit_source. Wikipedia's American Airlines fleet table (neutral) labels this config 'Transcontinental configuration, to be reconfigured into standard' with 15 aircraft in service as of 2025-12-31; American is standardizing these frames into the 190-seat single-First layout, so config.supersededBy points to aa-321-190 (the reconfiguration target, which is a real published file). FLEET RECONCILIATION: the FY2025 10-K reports 218 A321ceo mainline aircraft at an average of 184 seats; Wikipedia splits that into 203 standard (190 seats) + 15 transcon (102 seats), and (203*190 + 15*102)/218 = 184 and 203 + 15 = 218. PER-CABIN COUNTS are Wikipedia's citable figures: 10 First / 20 Business / 36 Main Cabin Extra / 36 Main Cabin = 102. 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-t-mce, canonicalTier extra_legroom_economy). ROW GRID IS DERIVED, not a placard scan (aa.com hard-403s bots; competitor seat-map sites are prohibited). Derivation: Flagship First lie-flat 1-1 (columns A/F) rows 1-5 = 10; Flagship Business lie-flat 2-2 (columns A/C/D/F) rows 6-10 = 20; Main Cabin 3-3 rows 12-23 = 72 (an unnumbered galley/lavatory divider occupies the gap at row 11). MCE zone = forward rows 12-15 (24) + the two over-wing exit rows 16 (6) and 20 (6) = 36; standard Main fills the remainder = 36. All 72 economy seats are modeled as full 3-3 rows to total Wikipedia's published 72 exactly; exact exit-passage seat removals are not modeled. The two over-wing exit rows and the wing span (rows 16-20) are DERIVED and approximate for this premium layout; the physical airframe is the classic A321-200 with four full door pairs (Doors 1-4) and two over-wing exit doors. The lie-flat nature of Flagship First (1-1) and Flagship Business (2-2) is American's long-standing transcontinental product; American does not publish A321T per-seat pitch/width/bed dimensions in any citable source, so all dimensions are flagged approximate/unsourced and recline is modeled as lie_flat. windowAlignment left 'unknown' on all window seats (derived grid). aircraft.windowGridType intentionally omitted (no a321ceo grid; A320-family grids carry no structural window blanks).
