Our rating engine's picks for this cabin layout — see any seat's full reasoning in the map above.

Pick these
  • 2A, 2K, 3A, 3K, 4A, 4K — True window single with direct aisle access — the most private Polaris seat for solo travellers.
Worth knowing
  • 11A, 11E, 11F, 11K — Last Polaris row — next to the mid-cabin galley and lavatories: foot traffic and noise.
  • 43D, 43E — Rear-most row — outer sections replaced by the aft galleys and lavatories; centre seats only, with noise and queueing behind.

How this map was built

United's Boeing 787-10 four-cabin international layout (United Polaris lie-flat business, United Premium Plus premium economy, Economy Plus extra-legroom economy, Economy). TOTAL 318 seats and the fleet count are published in United's FY2025 SEC Form 10-K (as of 2025-12-31: 21 787-10, all owned, 318 seats in standard configuration, average age 5.2 years) — the 10-K lists a SINGLE standard configuration for the type (a lone "318", unlike the 767-300ER "167-203" and 777-200ER "276-362" ranges that denote multiple subfleets), so only one flying config is modelled. The per-cabin split 44 Polaris / 21 Premium Plus / 54 Economy Plus / 199 Economy = 318 is from Wikipedia's United fleet table (neutral), whose 787-10 row is a single configuration (its "orders converted from 787-9, deliveries begin 2028" footnote refers to the 56 aircraft ON ORDER, which will be delivered in United's newer "Elevated" interior, not to a second config of the 21 currently flying). These 21 aircraft carry the legacy Polaris product (44 seats, no Polaris Studio), matching the pre-Elevated 787-9. ROW GRID IS DERIVED, not a placard scan: united.com is bot-blocked and competitor seat-map sites are prohibited sources. Class layouts (Polaris 1-2-1, Premium Plus 2-3-2, Economy Plus / Economy 3-3-3) and the Polaris lie-flat bed / 16-inch screen and Premium Plus / Economy Plus products come from United's Polaris (2016-17) and Premium Plus (2018) product releases and mirror the sister legacy 787-9 (ua-789-257). Derivations reproducing the published per-cabin totals: Polaris rows 1-11 (11x4=44); Premium Plus rows 12-14 (3x7=21); Economy Plus rows 15-20 (6x9=54, modelled as a contiguous forward block/separate cabin as on the 787-9 — the exact Economy Plus / Economy boundary and any non-contiguous exit-row E+ seats are not published); Economy rows 21-43 (rows 21-41 = 21 full rows x9 = 189, row 42 a 2-3-2 aft-taper of 7, row 43 a centre triple of 3 = 199). Row numbers, exit-row/door placement (Door 3 over-wing at row 29; wing band rows 28-36), furniture, and the two derived partial rows were constructed to reproduce United's published per-cabin totals and abreast layouts and may differ from the actual airframe. Pitch/width are not published by United and are flagged unsourced. windowAlignment left "unknown" on every window seat (derived grid; no published windowless seat on this type). The 56 787-10s on order (Elevated interior, from 2028) are a future subfleet, not modelled here.
