United Airlines Boeing 737 MAX 9 — mapa miejsc

United's standard 737 MAX 9 domestic three-cabin layout, and the only configuration United flies on the type. TOTAL 179 seats and the 120-aircraft fleet count are published in United Airlines Holdings’ FY2025 SEC Form 10-K (mainline fleet table, as of 2025-12-31: 737 MAX 9 — 120 aircraft, 76 owned / 44 leased, 179 seats each, average age 2.9 years; United is the largest MAX 9 operator). The per-cabin split 20 United First / 45 Economy Plus / 114 Economy = 179 is from Wikipedia's United fleet table (neutral) and reconciles exactly with the SEC 179 total. NOTE: this split (45 Economy Plus / 114 Economy) is the independently-verified figure; an earlier working estimate of 48 Economy Plus / 111 Economy was NOT confirmed by the cited sources and was discarded. Economy Plus is United’s branded extra-legroom economy product (canonicalTier extra_legroom_economy), confirmed as a near-fleet-wide product by United’s newsroom. THE ROW GRID IS DERIVED, not a placard scan: united.com is bot-blocked and competitor seat-map sites are prohibited sources. Exit geometry is grounded in Boeing’s 737 MAX ACAP (via the repo’s 737-900ER window grid, which shares the MAX 9 42.1 m fuselage): forward entry/service doors, TWO overwing emergency exits, and aft entry/service doors — no extra mid-cabin door. Derivation of seat rows: United First 2-2 (columns A/C/D/F) rows 1-5 = 20; forward galley/class divider occupies unnumbered row 6; Economy Plus 3-3 = 45, made of a forward block (row 7 through row 12) plus the two overwing exit rows (20-21 = 12). 45 Economy Plus seats cannot tile a pure 3-3 grid (45 = 7×6 + 3), so exactly one Economy Plus row is modeled as a 3-seat partial: row 7, the bulkhead row behind the class divider, is reduced to its right-hand triple (D/E/F) with the left triple (A/B/C) displaced by a forward closet/galley monument. The precise location of that de-configured triple is a structural INFERENCE, not a United-published fact. Standard Economy 3-3 fills rows 13-19 (42) and rows 22-33 (72) = 114. Overwing exits placed at rows 20-21 and the wing spanned rows 15-22 per typical 737 MAX 9 geometry; the forward overwing exit row (20) is modeled as non-reclining and the aft overwing exit row (21) with full recline, and economy row 19 (directly ahead of the exit) as limited-recline. United sells the overwing exit rows as Economy Plus. Actual row numbers, exit-row placement, over-wing range, the partial-row position and rear-monument positions may differ from the physical aircraft. All pitch/width/recline values are unpublished by United for this type and are flagged unsourced.
