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.

How this map was built

This is the ORIGINAL 178-seat layout (16 First / 24 Premium / 138 Main) that Alaska is converting away from: the 2024-25 fleet refresh grows Premium Class from 24 to 30 seats and shrinks Main Cabin to 132, keeping the 178 total and 16 First (successor config 16F/30W/132Y). First Class 16 seats and 178 total are confirmed by alaskaair.com and the Alaska newsroom expansion post; the 24-seat Premium figure is the newsroom's stated pre-expansion count. ROW GRID IS DERIVED from published cabin counts + layouts (First 2-2 on columns A/C/D/F; Premium & Main 3-3 on A-F), not from a published row-by-row map: First = rows 1-4 (16); no row 5 (forward galley/class divider); Premium = rows 6-9 (24); Main = rows 10-34 (138), with the last six rows (29-34) modeled as a 2-2 rear taper (outboard A/F seats absent as the fuselage narrows) so the aft-most row is 34 per Alaska's aircraft page while the total stays 138. Overwing exit rows placed at 16-17 per alaskaair.com. Actual aft-most row number and any numbering gaps may differ from this derivation. fleetCount reflects total 737-900ER airframes in the fleet (Wikipedia), not the number still in this specific sub-config mid-retrofit. Main Cabin pitch (31-32 in) and recline (3 in) are marked unsourced: the alaskaair.com page cited for them does not actually carry those figures. NOTE ON SOURCE INCONSISTENCY: Alaska's own 737-900ER page is internally inconsistent — its per-cabin seat figures (16 First + 42 Premium + 138 Main = 196) do not sum to the '178 seats' the same page states; we model the newsroom-sourced pre-expansion split of 16 First / 24 Premium / 138 Main = 178.
