No window at seat 11A — 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.

Best & worst seats

Our rating engine's picks for this cabin layout — see any seat's full reasoning in the map above.

Pick these
  • 17A, 17B, 17C, 17D, 17E, 17F — Exit row: significantly more legroom; occupants must be willing and able to assist in an evacuation (no infants).
Worth knowing
  • 11A — This is a window-position seat with no window — an air-conditioning riser duct runs behind the wall here, leaving a blank panel instead of a window.
  • 15A, 15B, 15C, 15D, 15E — Row directly ahead of the exit row: recline is limited to keep the exit path clear.

How this map was built

POST-REFRESH 178-seat 737-900ER layout (16 First / 30 Premium / 132 Main). The 2024-25 fleet refresh grew Premium Class from 24 to 30 seats by converting the six forward-most Main Cabin seats (one 6-abreast row) to Premium and adding USB-C/device holders; the 178 total and 16 First are unchanged. The 16/30/132 split is confirmed by the Wikipedia Alaska fleet table (current, post-refresh) and the Alaska newsroom expansion post (“Premium Class 24→ 30, six Main Cabin seats converted”); the refresh is in revenue service now (July 2026) — Wikipedia shows the 737-900ER fleet fully at 16/30/132 with no in-progress note (only the 737 MAX 8 remains under conversion to summer 2026). ROW GRID IS DERIVED from published cabin counts + layouts, not a published row-by-row map: First 2-2 on A/C/D/F rows 1-4 (16); no row 5 (forward galley/class divider); Premium 3-3 rows 6-10 (30, the added row 10 is the converted Main row); Main 3-3 rows 11-34 (132), with the last six rows (29-34) modeled as a 2-2 rear taper (outboard A/F absent as the fuselage narrows) so the aft-most row is 34 while the total stays 132. This is the same derivation as the pre-refresh as-739-178 with the Premium/Main divider moved aft exactly one row: Main rows 11-34 are unchanged, so the AC-riser structural window blank remains at 11A (5 rows forward of the fwd overwing exit at row 16; window grid 737-900ER, confirmed by window-alignment.js). Overwing exit rows 16-17 per alaskaair.com. NOTE ON SOURCE INCONSISTENCY: Alaska’s own 737-900ER aircraft page prose still describes the PRE-refresh split (“162 Main in rows 6-34 including 42 Premium in rows 6-9”) and is internally inconsistent (42 Premium cannot fit four 6-abreast rows); we model the post-refresh 16/30/132 from the newsroom + Wikipedia, and cite the aircraft page only for cabin structure (exit rows, door count). Main Cabin pitch (31-32 in) and recline (3 in), and First/Premium seat widths, are marked unsourced: no cited Alaska page carries those exact figures. fleetCount (79) is the total 737-900ER airframes (Wikipedia).

What changed

  1. Jul 14, 2026Set windowAlignment "none" on 11A (AC air-conditioning riser-duct blank; no window at this left-side seat). Source: engineering (window grid 737-900ER, alaska-windowless-2019); confidence high.
  2. Jul 14, 2026Initial creation of the POST-refresh 178-seat 737-900ER config (16F/30N/132Y). Built by transforming the lineage anchor as-739-178: Premium/Main divider moved aft one row (forward Main row converted to a 5th Premium row 6-10), Main rows 11-34 preserved verbatim (incl. 11A AC-riser blank), USB-C/device-holder refresh applied. Counts from Wikipedia (post-refresh 16/30/132) + Alaska newsroom (Premium 24→ 30). Retrofit target of as-739-178 (replaces).
