2026-09-30: Seat labels, numbering gaps, column letters and Economy Plus assignment transcribed from United's archived official map image; standard dimensions from the matching aircraft page. Economy Plus is a zone within a shared economy cabin. Source table/image conflicts are recorded in the UA audit. Window alignment is unknown. Only published limited-recline exceptions are flagged; ratings default to standard. The schematic furniture inventory is intentionally incomplete, so unverified adjacency/bassinet/window flags from the prior inferred grid were removed. Current per-tail fleet counts, hardware, connectivity rollouts and all legacy amenity descriptions remain outside the verified claims. Subtype attribution unresolved: source is United umbrella737-900 page, with no captured binding of this precise map to737-900 versus737-900ER. Inherited ER variant/window-grid attribution is not newly verified; no subtype rename or physical window alignment inferred.
What changed

- Sep 30, 2026Added United-published configuration with image-transcribed row labels and product zones; no fleet count or tail assignment inferred.
