The catch: which United 787 is on your booking?
United flies the 787-8, two versions of the 787-9 and the 787-10, often on overlapping routes, and the booking page just says “Boeing 787”. The 787-8 is the smallest. If you were hoping for the newest Polaris suites with doors, this is not that aircraft: it flies the older staggered Polaris seat, with no doors and no Polaris Studio.
The quickest tell is the seat count. 243 seats is the 787-8. On the seat map, Polaris ends at row 7 and economy runs to row 53. A 787-9 shows 257 or 222 seats, and a 787-10 shows 318.
The 787-8 is not a bad aircraft, and its eight-seat rear Polaris cabin is a pleasant place to sit. But it carries two traps a seat map will not warn you about: two Polaris seats with no window, and Economy Plus rows that only cover half the row.
Polaris business class (rows 1–7)
28 seats in a staggered 1-2-1, every one with direct aisle access: 20in wide, a 6ft 6in flat bed, a 16in screen, 110V AC and USB-A. The cabin is split by the door 2 galley into rows 1–5 (20 seats) and a private rows 6–7 mini-cabin (8 seats).
The stagger matters for window seats. In odd rows (1, 3, 5, 7) the A and L seats sit right against the window with the console on the aisle side; in even rows they sit nearer the aisle. Rows 1 and 6 are bulkheads with a wider footwell.
Best Polaris seats
- 4A — the only Polaris window with a great view; mid-cabin, nothing nearby. Its mirror, 4L, has a badly placed window.
- 3A, 3L — window seats tight to the glass, well clear of the galleys.
- 6A, 6L — bulkhead seats with a wider footwell, at the front of the eight-seat rear cabin.
- 1A, 1L — wider footwell at the front of the aircraft, first off.
- 4D/4F, 3D/3F, 6D/6F — the best centre pairs for two travelling together.
Polaris seats to avoid
- 5A and 5L — no window. A solid stretch of wall where the window should be. Same fare as 4A.
- 2A, 2L — the window is so far out of line that there is no real view.
- 7A, 7L — poorly aligned windows, and the Premium Plus bassinets mount directly behind.
Premium Plus (rows 20–22)
21 recliners in 2-3-2, letters A C | D E F | J L, with about 38in of pitch, a leg rest and a 13in screen. E is the only true middle seat. On the 787-8, row 20 is an ordinary bulkhead: plenty of legroom, but no floor storage for take-off and landing and trays in the armrests.
Best Premium Plus seats
- 21C, 21J — aisle seats with nothing flagged against them.
- 22A, 22L — the best-aligned windows in the cabin; economy bassinets mount in the row behind.
- 20A, 20L — bulkhead legroom at the window, but these are the bassinet positions.
Premium Plus seats to avoid
- 21A, 21L — the window sits behind the seat.
- 20E — a middle seat in the bassinet row.
Economy Plus: read the row, then read the letter
Economy Plus is sold at about 34in of pitch, three inches more than standard economy. On the 787-8 its 36 seats are scattered in a way that catches people out:
- Row 30 — all nine seats, at the bulkhead. No floor storage, trays in the armrests, bassinets at 30B and 30K. 30C and 30J have a partial wall with some extra room on one side.
- Row 31 — all nine seats. 31B to 31K are the best Economy Plus seats on the aircraft: real pitch, a seat in front, floor storage.
- Rows 32 and 33 — D, E and F only. 32A or 33K is standard economy at standard pitch.
- Row 42 — all nine, the exit row behind the mid-cabin lavatories.
- Row 43 — J, K and L only, at about 35in. 43J, 43K and 43L are the best-kept secret on this aircraft.
The exit row is not the prize it looks
- 42A and 42L — the exit door takes about 85% of the seat width, 8in ahead. 42L also has no window.
- 42C, 42D, 42E, 42F, 42J — the mid-cabin lavatories are immediately ahead.
- 42B, 42K — legroom with lavatory traffic alongside; 42K has open floor ahead.
Economy (rows 30–53)
3-3-3 at about 31in, letters A B C | D E F | J K L. There is no row 41, and row 40 has no centre block. Two lavatories sit mid-cabin ahead of row 42 and two more behind row 53.
Best economy seats
- 44A — the only economy window with a great view, in the first full row behind the exit.
- 43J, 43K, 43L — Economy Plus at about 35in, behind the right side of the exit row.
- Rows 34–36 — clean rows forward of the lavatories; the windows look over the wing.
- Rows 44–49 — the clean stretch of the rear cabin; for a window, take 45L, 46A, 48A or 48L.
Economy seats to avoid
- 38D–38F, 39C–39J, 40B, 40C, 40J, 40K — lavatory immediately behind.
- Rows 51–53 — the rear lavatories; rows 52 and 53 narrow as the cabin tapers.
- 30A, 30L, 33A, 33L, 37A, 37L, 50A, 50L — the window sits behind the seat.
