United Airlines Boeing 757-300 koltuk haritası

United's standard, single fleet-wide Boeing 757-300 domestic cabin. TOTAL 234 seats and the fleet count are PUBLISHED in United's FY2025 SEC Form 10-K (mainline fleet table, as of 2025-12-31: 21 Boeing 757-300, all 21 owned, 234 average seats, average age 23.3 years). The per-cabin split 24 United First / 54 Economy Plus / 156 United Economy = 234 is from Wikipedia's United fleet table (neutral: '24 — 54 156 234', United being the largest 757-300 operator). United First is United's domestic two-cabin first class (canonicalTier first); Economy Plus is United's branded extra-legroom economy (canonicalTier extra_legroom_economy). ROW GRID IS DERIVED, not a placard scan: united.com is bot-blocked and competitor seat-map sites are prohibited sources. Derivation: United First 2-2 (columns A/C/D/F) rows 1-6 = 24; forward galley/lavatory divider after row 6; a single Economy cabin (rows 7-41, 3-3) holds 210 seats. Economy Plus is United's non-contiguous 'sandwich', so it is modeled as a location-priced ZONE inside the Economy cabin (AUTHORING §6) rather than a separate cabin: E+ forward block rows 7-13 = 42 (7 exact full 3-3 rows) plus the two overwing exit rows 21-22 = 12, total 54; standard Economy rows 14-20 (42) and 23-41 (114) = 156. Every block divides evenly by 6, so no partial rows are forced. The Boeing 757-300 has two pairs of Type III overwing exits; they are placed at rows 21 and 22 (over the wing), projected from 757-300 wing/door geometry. Exact row numbers, any numbering gaps, the E+ 'sandwich' boundaries, the two overwing-exit rows, and any seats the real placard removes for exit access (e.g. Delta's 757-300 LOPA drops A/F on one overwing row) may differ from United's actual map. Per-seat recline is not published for United's 757-300, so no recline limits are asserted on the overwing exit rows (following the same discipline as the Delta 757-300 LOPA instance); the last row (41), which backs onto the aft galley, is marked limited_recline structurally. windowAlignment is left 'unknown' on all window seats (derived grid); no 757-300 engineering window grid exists in data/window-grids/, so aircraft.windowGridType is omitted. United does not publish 757-300 pitch/width; those values are approximate and flagged unsourced. IFE is modeled as streaming to a personal device (United Private Screening) — United's 757-300s are older (avg age 23.3 yr) and per-tail seatback-screen retrofit status is not published, so no seatback screen is asserted. fleetCount 21 is the 10-K 757-300 total; Wikipedia's live in-service count was also 21 at retrieval.
