Sơ đồ chỗ ngồi Japan Airlines Boeing 767-300ER

JAL's high-density two-class domestic 767-300ER (config codes A27 and A28, which share this layout and seat map). PUBLISHED on jal.co.jp (aircraft/conf/763, A27/A28 panel, PRIMARY): per-cabin counts Class J 42 / Economy 219 (total 261); per-class row ranges (Class J rows 1-7, Economy rows 15-50); emergency-exit rows (1 front, 28 front, 29 front, 50 rear) with over-wing exit-row seats 28A/C/H/K and 29A/C/H/K; the no-window seats 21A/K and 50A/K; lavatory positions (diaper-shelf lavatories 22 rear and 50 rear, wheelchair-accessible lavatory 50 DE rear); USB power (select aircraft) and Wi-Fi (no seatback entertainment listed). The seat GRID is READ from JAL's official seat-map image seatmap_en_a27 (PRIMARY): Class J 2-2-2 rows 1-7 (A,C/D,G/H,K = 42); Economy 2-3-2 (A,C/D,E,G/H,K). DERIVATIONS (why 'mixed'): the Economy count of 219 is reconciled to the map as rows 15-22 full (56), a reduced row 23 (A,C,D,E,G — the H/K window pair replaced by the mid-cabin lavatory at '22 Row Rear'), the over-wing exit row 28 fitted with only 28A/C/H/K (the centre D/E/G block taken by the mid-cabin galley — matching the published '28ACHK'), exit row 29 full, rows 30-49 full (140), and the last row 50 full (7; 50A/K no window); row numbers 24-27 are skipped across the mid-cabin galley/over-wing zone. 56 + 5 + 4 + 7 + 140 + 7 = 219. This 2-class layout has the same fuselage and aft cabin as the 3-class A25 but replaces the forward First+Class J block with a longer Class J cabin, so the forward Economy block extends two rows further (through row 22) than in A25. Seat dimensions from JAL's domestic seat pages (PRIMARY): Class J pitch ~97 cm / width ~47 cm; Economy pitch ~79 cm / width ~44 cm. No recline degrees published. WINDOW ALIGNMENT: window seats left 'unknown'; the map's 'No window' marking is encoded as windowAlignment 'none' on 21A/K and 50A/K only. No 767 window-grid engineering data, so windowGridType is omitted. Furniture is a structural interpretation of the published monuments (derived).
