How this map was built

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. The version-3 map labels the front product United Business while its table labels United First; this primary branding conflict remains unresolved.

What changed

  1. Oct 1, 2026Independent United source triage: version-bound power/USB/IFE, zero recline, exact staggered MAX8 labels and published exceptions, source-date/product wording qualification. Legacy inferred hardware, furniture and window uncertainty remain explicit. Qualify United outlet connector claims: generic availability remains prose, unsupported AC enum omitted, explicit wireless/StudioUSB-C preserved. No map, numbering, totals, coordinates or source archives changed.
  2. Sep 30, 2026Primary-source audit: updated published standard dimensions; reconstructed grid only where explicit archived airline image reconciliation is implemented. Remaining unverified scope documented in notes.
  3. Jul 14, 2026Initial creation of United 737-900/900ER single 179-seat config (20F/45N/114Y). Per-cabin counts from the Wikipedia United fleet article; United First width, AC power and headrest from United's 2015 narrowbody-interior release. Row grid, exit rows, monuments and the required 3-seat Economy Plus row derived from published counts + 737-900ER door/window geometry; pitches unsourced.
