Sơ đồ chỗ ngồi Delta Air Lines Boeing 767-400ER

Delta operates a single 767-400ER configuration (config 764). PUBLISHED (delta.com 767-400ER aircraft page): the "238 SEATS" accommodation header and per-cabin counts (34 Delta One / 20 Delta Premium Select / 28 Delta Comfort / 156 Delta Main), per-cabin seat/bed width and pitch (Delta One 20 in width / 77 in lie-flat bed [51 cm / 195.6 cm]; Premium Select 19.5 in / 38 in [50 cm / 97 cm]; Delta Comfort 18.1 in / 34 in [46 cm / 86 cm]; Delta Main 18.1 in / 31-32 in [46 cm / 79-81 cm]), child-seat-fit aircraft seat widths (19.9 / 19 / 18 / 18 in), under-seat item dimensions (Delta One and Premium Select: no under-seat storage; Delta Comfort 11.5x15x7.4 in; Delta Main 14x12x8.5 in), cabin amenities (Flat Bed, Wi-Fi, USB In-Seat Power, In-Seat Power Outlet, Personal Video, Satellite TV), 8 exits / 8 galleys / 6 lavatories (1 accessible), the wheelchair-accessible lavatory location ("Behind Row 56, Seats AB") and the movable-armrest (aisle) seat listing by row. PUBLISHED (official Delta LOPA image 767-400ER-INTL-764): the full row grid — Delta One 1-2-1 staggered lie-flat rows 1-9 (row 9 reduced to the A/D window suites, the centre position being a galley), Premium Select 2-2-2 rows 20-23 (row 23 reduced to the centre C/D pair), Delta Comfort 2-3-2 rows 30-33, Delta Main 2-3-2 rows 34-57 with rows 39 and 40 reduced to the centre C/D/E (lavatories flank row 39, the Door 3 exit flanks row 40) and row 57 reduced to the centre C/D/E (aft lavatories and Door 4 behind); the forward Main "Preferred" block (rows 34-42) is drawn in the lighter-blue/notched seat style; Doors 1-4, galleys, closets and lavatories. CROSS-CHECK: the movable-armrest listing reconciles exactly with the LOPA grid — Delta One 1 ABD/2 C/.../9 AD (row 9 has only A,D); Premium Select 20-22 BCDE, 23 CD; Delta Comfort 31-33 BCEF; Delta Main 34-38 BCEF, 39 CE, 41 CE, 42-56 BCEF, 57 CE (rows 39/40/57 centre-only, row 41 with fixed B/F armrests). All four cabin counts sum to 238 with no discrepancy, so layoutProvenance is "published_map". INFERRED: the Door 3 treatment — row 41 outboard A/B and F/G pairs are modelled as extra-legroom exit seats (tray-in-armrest per the fixed B/F armrests, no seat ahead across the door vestibule) with standard exit-row restrictions; row 40 centre seats are modelled as exit-door seats (high traffic, exit restrictions); the seats backing the row-39, row-56 and row-57 lavatories are modelled with limited recline; row 57 (last row, aft galley/Door 4 behind) is modelled with limited recline. Window alignment is "unknown" throughout — the LOPA shows no belt-line window positions and no 767-400ER engineering window grid exists in data/window-grids/, so windowGridType is omitted. Recline angles, screen sizes, the Delta One hardware model and the Wi-Fi provider are not printed on the page and are omitted or described qualitatively.
