Sơ đồ chỗ ngồi United Airlines Boeing 757-200

United's Boeing 757-200 modeled as a single currently-flying 176-seat configuration. TOTAL 176 seats and the fleet count are PUBLISHED in United's FY2025 SEC Form 10-K (mainline fleet table, as of 2025-12-31: 40 Boeing 757-200 — 39 owned, 1 leased — 176 average seats, average age 28.9 years, being replaced by the 737 MAX 9). The per-cabin split 16 United Polaris / 42 Economy Plus / 118 United Economy = 176 is from Wikipedia's United Airlines fleet table (neutral): a single 757-200 row, 40 in service, with the business count under the 'J United Polaris' column (lie-flat), 42 under Economy Plus (Y+) and 118 under Economy (Y). United Polaris on the 757-200 is a 2-2 lie-flat business cabin (canonicalTier business, cabinSummary code J); Economy Plus is United's branded extra-legroom economy (canonicalTier extra_legroom_economy, code N). RESEARCH NOTE: United historically operated multiple 757-200 sub-fleets (ex-United international and the retired premium-transcontinental 'p.s.' 169-seat 16F/45N/108Y layout). Neither the SEC 10-K nor the current Wikipedia fleet table shows a second currently-flying 757-200 configuration — the 10-K reports a single 176-seat average across all 40 airframes and Wikipedia lists one 757-200 row — so only the 176-seat layout is modeled here as citably current; the p.s./169-seat config is treated as retired/reconfigured. ROW GRID IS DERIVED, not a placard scan: united.com is bot-blocked and competitor seat-map sites are prohibited sources. Derivation follows standard 757-200 geometry (cross-checked against the published Delta 757-200 LOPA conventions in the golden set). United Polaris 2-2 (columns A/C/D/F) rows 1-4 = 16, with window beds marked no_direct_aisle_access; forward galley/lavatory after row 4 (rows 5-6 skipped for the monument). A single Economy cabin (rows 7-33, 3-3) holds 160 seats; Economy Plus is modeled as a location-priced ZONE inside the Economy cabin (AUTHORING section 6) rather than a separate cabin, as a non-contiguous 'sandwich': forward block rows 7-12 (36) plus the two mid-cabin door exit rows 12 and 21 (row 12 is shared as the forward edge of the block and the forward exit row) — the aft exit row 21 makes the zone non-contiguous — 42 Economy Plus total. Standard Economy = the eight over-wing rows 13-20 plus rows 22-33, 118 seats, with the last row (33) reduced to four seats (A/B/C/D) beside the aft lavatory to reconcile 160 economy seats in 3-3 (160 is not divisible by 6, so one reduced row is structurally required). The 757-200 uses full-size door pairs, not Type III over-wing hatches: doors 1L/1R (forward), 2L/2R (forward exit, ahead of the wing, row 12), 3L/3R (aft exit, behind the wing, row 21) and 4L/4R (aft) are projected from 757-200 door geometry. Exact row numbers, the numbering gap (rows 5-6), the Economy Plus 'sandwich' boundaries, the exit-row placements and the reduced last row may differ from United's actual map. windowAlignment left 'unknown' on all window seats (derived grid; no 757-200 engineering window grid exists in data/window-grids/, so windowGridType is omitted). United does not publish 757-200 pitch/width; those values are approximate and flagged unsourced. IFE is modeled as streaming to a personal device (United's fleet-wide baseline); the international-configured 757-200 Polaris cabin likely also has seatback screens, but this is not confirmed in the cited primary sources, so no seatback screen is asserted. fleetCount 40 is the 10-K 757-200 total, matching Wikipedia's in-service count of 40 at retrieval.
