The United Airlines Boeing 787-9 Dreamliner carries 257 passengers across Polaris Business + Premium Plus + Economy Plus + Economy. Power and Wi-Fi are available on this aircraft. Seats are rated below, so you can see which have the legroom, the window alignment and the quiet — and which sit next to a galley or lavatory.
The seats rated best on this map are 1A, 2A, 2L, 3A, 3L, 4A. Another 103 seats are rated best or good. The map marks 52 seats with extra legroom.
Seats rated avoid on this map are 34A, 34B, 34C, 34D, 34E, 34F. Another 19 seats are rated avoid. These are usually the back rows near the galley and lavatories, or middle seats with no window or aisle.
The seat design and flat-bed product are the same Polaris standard across United widebodies — the practical difference is the 787 cabin environment: lower altitude, better humidity, quieter engines. The one-two-one layout is identical on both aircraft types, so the seat experience per position is consistent.
Economy Plus gives noticeably more legroom in the forward Economy rows — same three-three-three width, but extra pitch that makes a real difference on a ten-hour-plus sector. United also reserves Economy Plus for elite MileagePlus members at check-in, so standard fare holders should select it early at booking to lock in the row.
The middle seat in any three-seat Economy block is the last resort for solo travellers — one neighbour on each side, no wall, and no easy aisle access. It works fine for two companions splitting a window and middle, or families taking a full three-seat block. Solo, the only reason to take it is if every window and aisle seat on the flight is gone.
