Japan Airlines Airbus A350-1000 seat map

JAL's international flagship A350-1000 (config code X35), the type replacing the 777-300ER on long-haul. Per-cabin counts and row ranges are stated directly on JAL's official A350-1000 (351) aircraft page (PRIMARY): First 6 (rows 1-2), Business 54 (rows 3-16), Premium Economy 24 (rows 17-19), Economy 155 (rows 45-62); total 239, corroborated by the Wikipedia JAL fleet table (NEUTRAL: 11 in service, 2 on order, 6/54/24/155=239). The seat GRID — every row and seat position, the staggered Business arrangement and the Economy taper — is READ from JAL's official English seat-map image (seatmap_x35_en, PRIMARY). Seat DIMENSIONS and screen sizes are from JAL's per-cabin A350-1000 seat pages (PRIMARY): First 1-1-1, seat/bed width ~123 cm, bed ~203 cm, 43-inch screen, wireless charging; Business 1-2-1 staggered, width/bed ~56 cm, bed ~198 cm, 24-inch screen, sliding door, wireless charging; Premium Economy 2-4-2, pitch ~107 cm, width ~48 cm, 16-inch screen, motorized fixed-shell recliner; Economy 3-3-3, pitch ~84-86 cm, width ~46 cm, 13-inch screen (12-inch on 45A/B/C/H/J/K). Recline figures are not published by JAL and are marked unsourced. LAYOUT DERIVATIONS (why 'mixed' not pure published_map): (1) Business rows 3-15 are full 1-2-1 staggered (A/D/G/K); the aftmost row 16 is fitted with only the centre pair 16D/16G to reconcile the published 54 against 14 row numbers (56 if all full) — this matches the map, on which the rearmost Business seats are a centre pair. (2) Economy rows 45-61 are full 9-abreast; the map shows the right block (K/J/H) and centre block (D/E/G) ending at row 61 and the left block continuing to a short row 62 — modelled as a 2-seat stub 62B/62C (window 62A dropped in the taper) to reconcile the published 155. (3) Economy column letters A,B,C / D,E,G / H,J,K are read from labels on the map (the centre block is D,E,G — F is not used; the movable armrest between 45D and 45E and the exit-row/screen notes list A,B,C,H,J,K). Special-seat facts from the page: no-shoe-storage on 3D, 8A, 8K (Business); no movable armrests in row 45 except between 45D and 45E; no non-reclining and no windowless seats on this aircraft. Exit doors: Door 1 (before row 1), Door 2 (before row 8), Door 3 (before row 45), Door 4 (aft of row 62). Lavatories at the Door-1/Door-2 galleys, aft of Premium Economy (row 19, incl. a wheelchair-accessible lavatory) and at the aft galley (row 62). No First/economy window-grid engineering data exists for the A350, so windowAlignment is left 'unknown' on window seats (the schematic map does not prove real window alignment) and windowGridType is omitted. Furniture and exact wing rows are structural interpretations of the schematic monuments (derived).
