Lufthansa Airbus A320ceo seat map

Layout transcribed row-by-row from the Lufthansa fleet PDF 202603_A320_168.pdf (revision 2026-03), the authoritative published seat map (this is the only current A320ceo PDF in the 320/ fleet directory — the neo is a separate 202603_A320neo_180.pdf, mapped as lh-320n-180). 28 rows of 3-3 (columns A B C | D E F); rows 13 and 17 are not used (skipped for superstition), so the seat rows are 1-12, 14-16 and 18-30 — 28 full six-abreast rows = the published 168 seats, with NO partial rows or blocked-middle reductions (the whole grid is regular). CLASSIC A320 FOUR-EXIT LAYOUT: forward doors (Door 1 L/R) ahead of row 1, TWO pairs of overwing emergency exits beside rows 11 and 12, and aft doors (Door 4 L/R) behind row 30. Forward galley/stowage (right/window-F side) + accessible lavatory (left/window-A side) with crew seats ahead of row 1; rear complex behind row 30 = two lavatories (both window sides) + a centre-rear galley + crew seats. MODELING OF THE BUSINESS/ECONOMY SPLIT (AUTHORING.md §6): Lufthansa short-haul is a Eurocabin — a single physical 3-3 economy deck. Business Class is created on the day by a MOVABLE divider at the front of the cabin, with the adjacent middle seat kept free; its extent varies flight-by-flight with demand (the PDF legend states explicitly: "Partition between Business and Economy Class according to demand" and draws the divider as a repositionable curtain around the row 7/8 boundary). Because the seats are identical economy hardware and no fixed cabin boundary exists, this is modeled as ONE economy cabin (canonicalTier economy) with the Business block expressed as a demand-dependent ZONE (representative maximum rows 1-7) rather than a separate cabin — modeling a fixed Business cabin would invent a divider position the source says is variable. No seat is assigned a business tier, so cabinSummary carries no J token. Location/legroom tiers within the one cabin are expressed as zones (per the corpus rule that non-contiguous or location-priced tiers are zones, not separate cabins): Preferred Zone = rows 8, 9, 10, 14 (forward Economy sold at a surcharge; identical hardware, flagged preferred_zone, rated standard as a location premium); Extra-legroom exit rows = 11 and 12 (Lufthansa "seat with more legroom" symbol; the two overwing-exit rows), given a distinct seatType (canonicalTier extra_legroom_economy) so they count as N in cabinSummary. DERIVATIONS / UNPUBLISHED: The Lufthansa seat-map PDF publishes row/seat identifiers, cabins, extra-legroom and Preferred-Zone seats, exits, galleys and lavatories, but NO numeric pitch or width and no amenity detail. All pitch/width/recline values are therefore unsourced estimates (marked unsourced/approximate), with the regular Economy pitch itself unpublished; the extra-legroom rows are marked by symbol only (no numeric delta on this PDF). windowAlignment is left "unknown" for the window seats (A/F): the map shows seat positions, not whether a structural window lines up, and the a320ceo engineering grid (data/window-grids/a320ceo.json) has an empty structuralBlanks list, so the window-alignment classifier writes nothing and reports full/partial only as low/medium priors. Wing extent, and forward/rear monument sides, are read from the diagram. Amenities (Wi-Fi, IFE) are from Lufthansa product pages, not this PDF.
