Peta kursi United Airlines Boeing 767-400ER

United operates a single Boeing 767-400ER cabin configuration. PUBLISHED: the SEC FY2025 Form 10-K lists 16 Boeing 767-400ER mainline aircraft at a single 231-seat count (average age 24.3 years) — a single figure, not a seat range, unlike the 767-300ER's 167-203 range that reflects two 763 sub-fleets; this confirms one 764 config. The Wikipedia United Airlines fleet table gives the cabin breakdown for the 16-aircraft 767-400ER: 34 United Polaris / 24 United Premium Plus / 48 United Economy Plus / 125 United Economy = 231. RETIREMENT: United has publicly signalled retiring its ageing widebodies, but as of the FY2025 10-K all 16 767-400ERs remain in service in this single config; no retrofit or second config appears in the cited primary/neutral sources, so status is 'active' and no supersededBy/successorPlanned link is set. DERIVATIONS (layoutProvenance derived_from_counts): Polaris is United's 1-1-1 all-aisle-access lie-flat cabin; 34 seats are laid out as a forward sub-cabin (rows 1-6) and a rear sub-cabin (rows 7-12), with rows 6 and 12 reduced to the two window singles (A/L) where the centre single yields to the door cross-aisles/galleys (10 full 1-1-1 rows x 3 = 30, plus 2 reduced rows x 2 = 4). Premium Plus rows 14-17 are 2-2-2 (4 x 6 = 24). Economy Plus rows 19-25 are 2-3-2 (rows 19-24 full = 42; row 25 reduced to 6 seats where the centre-middle seat is not installed beside the mid-cabin galley = 6; total 48). Economy rows 27-44 are 2-3-2 (17 full rows x 7 = 119; row 41 reduced to 6 seats at a mid-cabin galley bank; total 125), with the Door 3 over-wing exit at row 34 and the last row 44 backing the aft galley/Door 4. Door positions (Doors 1-4), galley/lavatory banks, the over-wing band and the section splits are DERIVED and may differ from the actual airframe. Column letters (window-left A ... window-right L, centre single E in Polaris, centre-middle E in the 2-3-2 cabins) follow United's booking convention as a derived scheme. No 767 engineering window grid exists in the corpus, so window seats carry windowAlignment 'unknown' and aircraft.windowGridType is omitted. Pitch/width/bed and screen dimensions are not published by United for this aircraft and are flagged unsourced estimates.
