Delta Air Lines Boeing 757-300 koltuk planı

PUBLISHED (delta.com 757-300 page, config 75Y — Delta's only 757-300 configuration): per-cabin seat counts (24 Delta First / 38 Delta Comfort / 172 Delta Main = 234), seat width/pitch per cabin (First 20.9 in / 37-38 in; Comfort 17.3 in / 33-34 in; Main 17.3 in / 30-31 in), underseat dimensions, aircraft dimensions/range (3,285 mi, 178 ft 7 in), 12 exits, 3 galleys, 5 lavatories, and cabin amenities. PUBLISHED (official Delta 75Y LOPA seat-map image): the full row grid — Delta First 2-2 rows 1-6 (row 1 bulkhead), Delta Comfort 3-3 row 14 (reduced to D/E beside the 2L/2R doors) plus rows 15-20, Delta Main 3-3 rows 21-49 with two over-wing arrow exit pairs ahead of rows27 and28 (row 28 reduced to B/C/D/E with A/F removed for exit access), mid-aft 3L/3R doors ahead of row 41, and forward/mid/aft galleys, lavatories and a forward closet. Movable-armrest accessibility data on the page (First 2-6 BC; Comfort 15 D, 16-20 CD; Main 21-40 CD, 42-49 CD) corroborates the cabin row spans and marks rows 14 and 41 as structurally distinct. INFERRED: the over-wing exit rows 27 and 28, and row 41 (immediately aft of the 3L/3R doors), are modeled as extra-legroom Delta Preferred exit seats with the standard evacuation restrictions (no infants or unaccompanied minors); the LOPA does not print per-seat recline, so no recline limits are asserted on the exit rows (row 49, the last row backing onto the aft galley, is marked limited_recline structurally). Over-wing rows 27-30 carry the LOPA Preferred corner markers and are flagged over_wing. Window alignment is 'unknown' — the LOPA does not show window belt-line positions and no 757-300 engineering window grid exists in data/window-grids/, so windowGridType is omitted. Delta operates 16 Boeing 757-300s, all in this single 75Y configuration. Follow-up native-source qualification: marker notches denote Preferred seats, not wing views. Retained wing ranges and recline/legroom inferences remain approximate, not engineering certification. USB connector and outlet electrical type, unbound seat hardware and Wi-Fi prices are unverified. No underseat storage is applied throughout cabins where the aircraft page states it explicitly; fixed armrest or omitted dimensional cells alone are insufficient. Fleet counts retain their historical December2025 neutral-source period rather than a July2026 retrieval date. Preferred markers are on21–25ACDF, all27,29ACDF and all41; row28 is unmarked. Comfort14DE has no adjacent galley.
