Sơ đồ chỗ ngồi United Airlines Boeing 737-700

United's standard 737-700 domestic three-cabin layout, the oldest 737 sub-fleet in the mainline (average age 26.8 years per the FY2025 10-K). TOTAL 126 seats and the 40-aircraft fleet count are published in United's FY2025 SEC Form 10-K (mainline fleet table, as of 2025-12-31: 40 aircraft, 38 owned / 2 leased, 126 seats each, avg age 26.8 yrs). The per-cabin split 12 United First / 36 Economy Plus / 78 Economy = 126 is from Wikipedia's United fleet table (neutral), and reconciles exactly with the 10-K total. Economy Plus is United's branded extra-legroom economy product (canonicalTier extra_legroom_economy). The -700 is NOT retired: 40 airframes remained in service at 2025-12-31; the type is being drawn down but still flies. 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 1-3 = 12; forward galley/class divider occupies unnumbered rows 4-6 (United starts the main cabin at row 7 across its 737 family — see ua-738-166); Economy Plus 3-3 forward block rows 7-11 = 30 plus the single over-wing exit row 16 = 6 (United sells the over-wing exit row as Economy Plus) = 36; standard Economy 3-3 fills rows 12-15 (24) and rows 17-25 (54) = 78. The 737-700 has a SINGLE over-wing exit pair (one exit per side), unlike the two pairs on the -800/MAX 8, so there is one exit row (16) with full recline, the row directly ahead of it (15) modeled with limited recline, and the wing spanned rows 14-18 per typical 737-700 geometry. 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 All pitch/width/recline values are unpublished by United for this type and are flagged unsourced.
