Sơ đồ ghế British Airways Airbus A321neo

Layout read row-by-row from British Airways' official Scene7 representative seat-map raster for the A321 (asset airbus-A321-full-seatmap, PRIMARY, layoutProvenance published_map). This is BA's ONLY current A321 seat map: per the Wikipedia British Airways fleet table (NEUTRAL) the current passenger fleet lists an Airbus A321neo row (20 in service, 2 on order) and NO separate A321-200/A321ceo row, so BA no longer flies the A321ceo as a distinct passenger type; the generic "A321" asset name is therefore the A321neo. 37 rows of 3-3 (columns A B C | D E F). Forward Door 1 (L/R) with a forward accessible lavatory (left) and galley (right) plus a galley bank directly ahead of row 1; two overwing emergency-exit pairs beside row 9 (forward of wing box) and row 23 (aft of wing box) — at BOTH exit rows the window seats A and F are deleted for the exit, so rows 9 and 23 are 4-abreast (B C D E); aft Door 4 (L/R) with two rear lavatories (left one wheelchair-accessible, one centre) and a rear galley (right) behind row 37. MODELLING OF CLUB EUROPE / EURO TRAVELLER (AUTHORING.md §6, same pattern as ba-320n-180 / lh-320n-180): BA short-haul is a Euro-style single deck — one physical 3-3 economy cabin in identical hardware. Club Europe (business) is created by a MOVABLE divider at the front with the adjacent middle seat kept empty; its extent varies flight-by-flight with demand. Because the seats are the same economy hardware and no fixed cabin boundary exists, this is modelled as ONE economy cabin (canonicalTier economy) with Club Europe expressed as a demand-dependent ZONE (representative maximum rows 1–14) rather than a separate cabin, and NO seat carries a business tier, so cabinSummary carries no J token. On the representative raster the Club Europe middle seats (columns B and E, rows 1–14) are drawn blocked; they are modelled as physical seats with bookable:false, unsellableReason guaranteed_empty and the blocked flag. totalSeats 218 counts all physical seats (35 full rows × 6 + rows 9 and 23 × 4). The 28 blocked Club Europe middles (14 rows × B/E) make sellableSeats 190 in this representative layout: Club Europe sold = 54 (rows 1–14, columns A/C/D/F, minus the deleted 9A/9F at the forward overwing exit) and Euro Traveller sold = 136 (rows 15–37 × 6, minus the deleted 23A/23F). SOURCE RECONCILIATION (AUTHORING §5b): the Wikipedia fleet table lists the A321neo as 56 Club Europe + 136 Euro Traveller = 192 sellable. Euro Traveller matches exactly (136). Club Europe differs by 2 seats: Wikipedia's 56 is the notional forward-zone count (14 rows × 4 = 56, treating row 9 as a full 4-seat row), whereas the representative raster deletes 9A/9F for the forward overwing exit, giving 54 sold; the Club Europe partition is movable so the sold count is inherently demand-dependent. The directly-observed primary raster wins for layout, so this file carries the raster counts (54 CE / 190 total sellable) and records the 2-seat difference here and in a caveat on the Wikipedia source. RATINGS: Club Europe sold seats (rows 2–14, A/C/D/F) are rated good for the guaranteed-empty adjacent middle (a concrete space/privacy advantage, not position). Row 1 is a bulkhead behind the forward galley (be_aware). Rows 9 and 23 are the overwing exit rows — extra legroom, with exit-duty restrictions (good). Row 37 is the last row backing onto the rear galley/lavatories (be_aware). DERIVATIONS / UNPUBLISHED: BA labels the map "representative" (config.representative true); the real per-flight layout appears in Manage My Booking and the divider position varies. The raster shows seat arrangement, blocked middles, exits, galleys, lavatories, carry-cot legend and moveable-armrest markers, but NO numeric pitch/width/recline and no legroom or preferred-seat marking. All seat-type dimensions are therefore unsourced estimates (unsourced/approximate). windowAlignment is left unknown for window seats (A/F): the schematic raster shows seat positions, not whether a structural window lines up, and the a321neo engineering grid has no structural blanks (structuralBlanks empty), so window-alignment.js writes nothing on --apply. Wing extent (deck.wing) is a visual estimate from the diagram bracketed by the two overwing exits. Amenities (Wi-Fi, streaming IFE, USB power) are from BA short-haul product information, not this raster.
