Sơ đồ chỗ ngồi United Airlines Airbus A321neo

United's standard, single fleet-wide A321neo cabin. TOTAL 200 seats and the fleet count are published in United's FY2025 SEC Form 10-K (as of 2025-12-31: 59 A321neo, 51 owned / 8 leased, 200 seats each, average age 0.9 years). The per-cabin split 20 United First / 57 Economy Plus / 123 Economy = 200 is from Wikipedia's United fleet table (neutral); Economy Plus is United's branded extra-legroom economy (canonicalTier extra_legroom_economy). United's own 'United Next' fleet/premium press release (via PR Newswire, 2026-03-24) confirms this standard A321neo is the current build and that the 161-seat lie-flat-Polaris 'Coastliner' A321neo is a SEPARATE future subfleet (50 aircraft; 'will start flying this summer' 2026; Wikipedia: deliveries begin 2026) — no primary source confirms a Coastliner in revenue service as of retrieval, so only the standard config is modeled here. ROW GRID IS DERIVED, not a placard scan: united.com is bot-blocked and competitor seat-map sites are prohibited sources. Derivation: United First 2-2 (columns A/C/D/F) rows 1-5 = 20; forward galley/lav divider after row 5; a single Economy cabin (rows 7-37, 3-3) holds 180 seats. Economy Plus is United's known non-contiguous 'sandwich', so it is modeled as a location-priced ZONE inside the Economy cabin (AUTHORING §6) rather than a separate cabin: E+ zone rows 7-16 = 57, standard Economy rows 17-37 = 123. Because 57 and 123 are each odd while a 3-3 row holds 6, the split forces one partial row in each block: row 7 is a 3-seat E+ partial behind a forward-right galley/closet monument, and row 37 is a 3-seat Economy rear taper into the aft-right lavatory/galley. The two Airbus Cabin Flex Type III+ overwing exits are placed at rows 11 (forward, non-reclining) and 12 (aft, full recline), with row 10 just ahead (limited recline), projected from the A321neo ACF door/wing geometry (data/window-grids/a321neo.json). Exact row numbers, any numbering gaps, the E+ 'sandwich' boundaries, the two partial-row monument positions and the overwing-exit rows may differ from United's actual map. windowAlignment left 'unknown' on all window seats (derived grid; Airbus has no published windowless seat on this type). United does not publish A321neo pitch/width; those values are approximate and flagged unsourced. fleetCount 59 is the 10-K A321neo total (Wikipedia's live in-service count was higher at retrieval).
