Sin ventanilla en el asiento 10A — Boeing routes the air-conditioning riser ducts up the left sidewall from the belly A/C packs to the ceiling distribution ducts, forward of the wing. The duct behind the sidewall panel displaces one left-side cabin window. Per Alaska fleet engineering this is standard on all 737 aircraft.

Cómo se construyó este mapa

Single United domestic three-cabin layout shared by United's Boeing 737-900ER (136 aircraft) and 737-900 (12 aircraft): 20 United First (2-2), 45 Economy Plus, 114 United Economy = 179 seats, per the Wikipedia United Airlines fleet article (both variants list the identical 20/45/114/179 seating). United publishes NO row-by-row seat map through an accessible primary source (united.com is bot-blocked), so the ROW GRID IS DERIVED from those per-cabin counts plus standard 737-900ER geometry and the type's window grid (data/window-grids/737-900ER.json): United First = rows 1-5 (2-2 on A/C/D/F, 20 seats), row 1 the bulkhead; rows 5-7 hold the forward galley/lavatory and class-transition area; Economy Plus = rows 7-14 (3-3, 45 seats); Economy = rows 15-33 (3-3, 114 seats = 19 full rows). Because 45 is not divisible by 6, exactly one 3-abreast row is required in Economy Plus; it is modeled as the forward Economy Plus bulkhead (row 7, left triple only) beside a forward-right galley/closet monument. The two 737-900ER overwing exits are modeled at rows 15 (forward, seatback fixed / no recline) and 16 (aft, normal recline); row 14 (last Economy Plus) sits directly ahead of the forward exit and is modeled with limited recline. Whether United markets the overwing exit rows as Economy Plus or Economy is not determinable from the derived layout; they are modeled inside the Economy cabin (extra-legroom exit seats) so the 45/114 product split matches the published counts. Exact row numbers, exit-row numbers, wing span, monument placement and the last-row treatment are DERIVED, not read from a published United map. Per Alaska Airlines fleet engineering (window grid source alaska-windowless-2019) all 737s have one windowless left-side seat (column A) forward of the wing from the air-conditioning riser duct — 11A on the 737-900/900ER in Alaska's numbering; the exact United seat cannot be pinned on this derived layout, so every window seat is left windowAlignment 'unknown' (the classifier reports it as a medium-confidence geometric projection only). Seat pitches are not published by United through an accessible primary source and are marked unsourced; United First width (21.1 in) is sourced from United's 2015 narrowbody-interior release. fleetCount 148 = 136 737-900ER + 12 737-900 (Wikipedia).
