Sơ đồ ghế Delta Air Lines Boeing 757-200 — 75D

PUBLISHED (delta.com 757-200 page, config 75D): per-cabin seat counts (20 Delta First / 35 Delta Comfort / 144 Delta Main = 199), seat width/pitch per cabin (First 20.9 in / 36-37 in; Comfort 17.3 in / 33-34 in; Main 17.3 in / 31-32 in), and cabin amenities. PUBLISHED (official Delta 75D-H LOPA seat-map image, shared with 75H): the full row grid — Delta First 2-2 rows 1-5, Delta Comfort 3-3 rows 15-21 (row 17 reduced to A/B/C beside a mid-cabin lavatory, row 18 reduced to D/E beside the 2L/2R doors), Delta Main 3-3 rows 22-45, over-wing exits ahead of rows 26 and 27, and forward/aft galleys, lavatories and closet. INFERRED: over-wing exit rows 26 and 27 are modeled as extra-legroom Delta Preferred seats with the standard evacuation restrictions; the LOPA does not print per-seat recline, so no recline limits are asserted on the exit rows (row 45, the last row backing onto the aft galley/lavatories, is marked limited_recline structurally). Over-wing rows 26-29 carry the LOPA wing-view corner markers and are flagged over_wing. 75D has 10 exits and a 3,370 mi range. This 75D subfleet shares its published LOPA image with config 75H but is a distinct Delta fleet code with slightly different published seat width (Comfort/Main 17.3 in vs 75H 17.2 in), Main pitch (31-32 in vs 75H 30-32 in) and range (3,370 vs 3,980 mi). Window alignment is 'unknown' — the LOPA does not show window belt-line positions and no 757-200 engineering window grid exists in data/window-grids/. Delta operates 76 total 757-200s across configs 75D/75G/75H/75S; the per-config airframe split is not published, so fleetCount is omitted.
