United Airlines Boeing 737 MAX 8 seat map

United's standard 737 MAX 8 domestic three-cabin layout (United 'signature interior'). TOTAL 166 seats and the 123-aircraft fleet count are published in United's FY2025 SEC Form 10-K (as of 2025-12-31: 123 aircraft, 107 owned / 16 leased, 166 seats each, average age 2.4 years). The per-cabin split 16 United First / 54 Economy Plus / 96 Economy = 166 is from Wikipedia's United fleet table (neutral), whose row for the 737 MAX 8 reads 16 First / — / 54 Economy Plus / 96 Economy / 166. NOTE ON THE ASSIGNMENT HINT: the dispatch hint guessed 16F/48E+/102Y (identical to United's 737-800) 'but verify independently'; independent verification against the cited Wikipedia table instead gives 54 Economy Plus / 96 Economy for the MAX 8 (same 166 total and same 16 First, but a larger Economy Plus zone than the -800's 48/102). The 48/102 figure belongs to the 737-800, not the MAX 8. Economy Plus is United's branded extra-legroom economy product (canonicalTier extra_legroom_economy), confirmed fleet-wide by United's newsroom. Wikipedia also lists a niche 'Guam-based configuration' (total 164) for the MAX 8; that regional sub-fleet variant is not the mainline config modeled here and its full per-cabin split is not cleanly published, so it is out of scope for this single mainline config. The ROW GRID IS DERIVED, not a placard scan: united.com is bot-blocked and competitor seat-map sites are prohibited sources. Derivation: United First 2-2 (columns A/C/D/F) rows 1-4 = 16; forward galley/class divider occupies unnumbered rows 5-6; Economy Plus 3-3 forward block rows 7-13 = 42 plus the two overwing exit rows 20-21 = 12 (United sells overwing exit rows as Economy Plus) = 54; standard Economy 3-3 fills rows 14-19 (36) and rows 22-31 (60) = 96. Overwing exits placed at rows 20-21 and the wing spanned rows 15-22 per typical 737 MAX 8 geometry (door/exit stations in data/window-grids/737-max8.json come from the Boeing MAX ACAP table); the forward exit row (20) is modeled as non-reclining and the aft exit row (21) with full recline. Actual row numbers, exit-row placement, over-wing range 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 All pitch/width/recline values are unpublished by United for this type and are flagged unsourced.
