Korean Air Airbus A321neo seat map

Korean Air's single-aisle A321neo, the airline's first narrowbody with a 180-degree fully lie-flat business seat (in service since Nov 2022; 20 aircraft in service, 36 on order per Wikipedia's Korean Air fleet table). PUBLISHED MAP: the row grid, cabin split, column layout and all monuments come from Korean Air's OWN published A321neo (182-seat) seat-map image (koreanair.com dam asset, retrieved via Wayback raw bytes) — hence layoutProvenance 'published_map'. That map shows Prestige (Business, class code C/J) in a 2-2 layout at rows 7-8 (columns A/B | D/E = 8 seats) and Economy in 3-3 at rows 28-56 (columns A/B/C | D/E/F = 29 rows x 6 = 174 seats; Korean Air uses a wide-gap numbering scheme, business 7-8 then economy 28-56). SEAT PRODUCTS/DIMENSIONS come from Korean Air's 2022-11-30 A321neo newsroom press release (primary; koreanair.com returns 403 to non-browser clients so the snapshot is a rendered-text extract of the verbatim material facts, cross-confirmed against inflight-online.com and airlinegeeks.com): Prestige = 180-degree fully lie-flat, 44 cm (17.3 in) personal monitor, wireless smartphone charger; Economy = 33 cm (13 in) personal monitor (largest in the narrowbody fleet), adjustable headrest, individual coat hook, backrest reclining up to 121 degrees. Korean Air's own asset path names the business seat 'Prestige Sleeper' (matching Wikipedia's fleet-table label); this A321neo 'Prestige Sleeper' is a NEW fully-flat 2-2 seat and is a different physical product from the older 2-3-2 angled-flat 'Prestige Sleeper' on the widebodies. DERIVATIONS / JUDGEMENT CALLS: (1) Business PITCH and WIDTH are not published by Korean Air and are omitted rather than estimated (widely-quoted 63 in / 19 in figures are from travel-press reviews = secondary, not cited for dimensions). (2) In the 2-2 business layout the window seats (A/E) lack direct aisle access — flagged no_direct_aisle_access. (3) PREFERRED ZONE: Korean Air's map color-codes forward Economy (rows 28-31) and the aft over-wing exit row (39) as a distinct selectable seat category (green = extra-legroom, purple/star = preferred); modeled as a 'Preferred Seats' zone with preferred_zone flags. The map legend TEXT was not retrievable, so no per-seat FEE is asserted (paid_seat omitted); forward/preferred seats with ordinary hardware are rated 'standard' per the house rubric, and only the genuinely extra-legroom seats (28 D/E/F, exit row 39) are rated 'good'. (4) Row 28 is a bulkhead: the map marks D/E/F extra-legroom (open bulkhead) but A/B/C standard (behind the forward closet) — reproduced faithfully. (5) Over-wing exits: the map shows two Type III+ over-wing exit pairs at rows 38 (before) and 39 (before), matching the A321neo Airbus Cabin Flex arrangement (windowGridType a321neo). Row 38 (between the exits) has standard legroom on the map; row 39 (aft of the second exit) has extra legroom. Infant / unaccompanied-minor restrictions on rows 38-39 are the universal exit-row regulatory facts. (6) Wheelchair-accessible seats are shown at 28C, 29B, 29C, 31B, 31C (no SeatLink flag exists for accessible seats, so they are noted here, not flagged). (7) An unidentified seat glyph appears at 36F and 53F on the map (window seats); its meaning was not determinable from the map alone and is left unmodeled. (8) windowAlignment is 'unknown' on all window seats: the a321neo window grid has no structural blanks and the classifier's full/partial belt priors are report-only (never written). Wing rows (35-44) are an approximate reading of the map's wing shading. IFE/Bluetooth: Wikipedia states the A321neo has Bluetooth-capable business screens but gives the screen as '24-inch 4K' — this conflicts with Korean Air's own 44 cm (17.3 in) figure, so the primary 17.3 in is used and Bluetooth is retained as a feature.
