United Airlines 787-9 Seat Selection Guide (2026)
✈️ Quick Verdict
Aircraft: Boeing 787-9, two layouts — 257 seats (48 Polaris, 21 Premium Plus, 188 economy) or 222 seats “Elevated” (64 Polaris suites, 35 Premium Plus, 123 economy)
Version lottery: Yes, and it is the biggest in United’s fleet. Only the 222-seat jet has doors, Polaris Studio and 4K OLED screens. The 257-seat layout is still the large majority.
Best seats, 257-seat: Polaris 3A, 3L, 7A, 7L · Premium Plus row 21 · economy 48A, 48L, 55A, 55L
Best seats, Elevated: Studio 1A or 1D/1F · suite 4A, 8L · Premium Plus 22A, 22L · economy 32A, 32L, 35A, 35L
Seats to avoid: 257-seat 5A, 5L (no window), row 20, 30A–C, 30J–L, rows 34–35 · Elevated 24A, 24L (no window), rows 30–31, row 43
Wi-Fi: satellite Wi-Fi on both · Screens: 16in in Polaris on the 257-seat jet; 19in 4K OLED (27in in Studio) on the Elevated jet

The catch: two 787-9s, one name
Both aircraft appear as “Boeing 787-9” at booking, on the same routes and at the same fares. One has a Polaris suite with a sliding door, a 19in 4K OLED screen and, in two rows, the larger Polaris Studio. The other has the older Polaris seat with no door. If you are paying for Polaris and the door matters to you, check before you buy.
| Check | 257-seat (older Polaris) | 222-seat (Elevated) |
|---|---|---|
| Total seats | 257 | 222 |
| Polaris | 48 seats, rows 1–12, no doors | 64 suites, rows 1–17 (no row 13), all with doors; 8 Polaris Studio in rows 1 and 9 |
| Premium Plus | 21 seats, rows 20–22 | 35 seats, rows 20–24 |
| Economy | 188 seats, rows 30–57 (no rows 36–41) | 123 seats, rows 30–44 |
| Screens | 16in in Polaris | 19in 4K OLED in Polaris, 27in in Studio, 4K throughout |
| Power | 110V AC + USB-A | 110V AC + USB-C, Bluetooth audio, wireless charging in Polaris |
How to tell from the seat map: if Polaris runs to row 17 and skips row 13, it is the Elevated jet. If it ends at row 12, it is not. Economy ending at row 44 confirms Elevated; running to row 57 confirms the older layout.
Which is more likely? The 257-seat layout is still most of the fleet. United is adding Elevated 787-9s through 2026 and beyond, but treat one as something to look for on a specific flight, not something to expect. Aircraft swaps happen, so check again at check-in.
The trade-off: the Elevated jet wins in every premium cabin, but it has 65 fewer standard economy seats. Economy Plus and the good economy windows sell out sooner.
Seat letters
United’s 787s skip G, H and I. Polaris is A | D F | L; Premium Plus is A C | D E F | J L; economy is A B C | D E F | J K L. A seat called 4K or 20B does not exist on this aircraft.
The 257-seat 787-9 (older Polaris)
Polaris (rows 1–12)
48 staggered seats, all with direct aisle access, in an eight-row forward cabin and a four-row rear cabin behind the door 2 galley. 20in wide, 6ft 6in bed, 16in screen, no door. Rows 1 and 9 are bulkheads with a wider footwell; row 1 is also where the bassinets mount.
Best Polaris seats
- 3A, 3L, 7A, 7L — window seats tight to the glass with two windows each.
- 9A, 9L — bulkhead seats with a wider footwell at the front of the rear cabin. A lavatory sits just ahead of 9L, so 9A is the calmer of the two.
- 11A, 11L — mid rear cabin, nothing nearby; the view is over the wing.
- 3D/3F, 7D/7F, 10D/10F, 11D/11F — centre pairs for couples.
Polaris seats to avoid
- 5A and 5L — no window. A windowless stretch of wall beside the seat.
- 8A, 8L — the window is so far out of line there is no real view.
- 2A, 2L, 4A, 4L, 6A, 6L, 10L, 12A, 12L — poorly aligned windows.
- Row 12 — the Premium Plus bassinets mount directly behind.
Premium Plus (rows 20–22)
21 seats in 2-3-2, about 38in of pitch. Row 20 is a cramped bulkhead on this aircraft: the wall sits about 21–23in ahead, closer than a normal bulkhead, and it is also the bassinet row (20A, 20E, 20L). It looks like the legroom row on a seat map and it is not.
Best Premium Plus seats
- 21A, 21L — two windows each, a seat in front, floor storage.
- 21C, 21J — the cleanest aisles.
Premium Plus seats to avoid
- Row 20 — cramped bulkhead, no floor storage, bassinets.
- Row 22 — the Economy Plus bassinets mount directly behind.
Economy Plus: the cramped bulkhead and the lavatory row
39 seats sold at about 34in. They are spread across rows 30–34, 42 and 44, and two parts of that are traps:
Economy Plus seats that are worse than they look
- 30A, 30B, 30C, 30J, 30K, 30L — the bulkhead wall is only about 16–17in ahead, much closer than normal. Only 30D, 30E and 30F get real bulkhead legroom.
- 34A, 34B, 34C — sold as Economy Plus, but the mid-cabin lavatory bank is directly behind. Rows 34 and 35 are the worst rows on the aircraft.
- Row 42 (A–C and J–L only) — the exit row, with the lavatories directly ahead; at 42A and 42L the exit door takes 80–85% of the seat width and the window sits behind the seat.
The good Economy Plus seats: rows 32 and 33 in A–C and J–L (in those rows D, E and F are standard economy), and 44D and 44F, a bulkhead pair with extra legroom behind the exit row, though with no floor storage for take-off and landing. 44E is the bassinet.
Economy (rows 30–57)
3-3-3 at about 31in. Rows 36 to 41 do not exist, and rows 42 and 43 have no centre block. All four economy lavatories sit mid-cabin, ahead of row 42; there are none at the back, so the last rows are calmer than on most widebodies.
Best economy seats
- 48A, 48L, 55A, 55L — the four windows with a great view.
- 56B/56C, 56J/56K, 57B/57C, 57J/57K — the cabin narrows to 2-3-2, so the B and K seats have no neighbour on the window side. Good pairs for two.
Economy seats to avoid
- Rows 34 and 35 — the lavatory bank is directly behind every seat.
- 47A, 47L, 54A, 54L — the window sits behind the seat.
The 222-seat 787-9 Elevated
Polaris suites and Polaris Studio (rows 1–17)
64 suites in 1-2-1, all with sliding doors: 21in wide, 19in 4K OLED screen, Bluetooth audio, wireless charging and USB-C. There is no row 13. Rows 1–8 are the forward cabin; rows 9–17 sit behind the door 2 galley and a pair of lavatories. The centre suites are set further apart in rows 1–8 than from row 9 back, so the forward centre suites feel more private.
Polaris Studio is eight larger suites with a 27in screen and an ottoman a companion can sit on for dinner. They are in row 1 and row 9 only — and the two rows are not equal. Row 9 sits directly behind the mid-cabin lavatories and galley; row 1 is the calmer Studio row, apart from 1L, which has the forward right-hand lavatory just ahead.
Best Elevated Polaris seats
- 1A — a Studio suite in the calmer Studio row.
- 1D/1F — the Studio centre pair, the best choice for two.
- 4A, 8L — standard suites with a great window view.
- 14A, 14L, 15A–17A, 15L–17L — clean rear-cabin window suites.
Elevated Polaris seats to watch
- 9A, 9D, 9F, 9L — Studio at Studio prices, but directly behind the lavatories and galley.
- 3L, 5A, 5L, 6A — badly aligned windows.
Premium Plus (rows 20–24)
35 seats in 2-3-2 — United’s largest Premium Plus cabin — with a 16in 4K screen, Bluetooth and wireless charging. Row 20 is a normal bulkhead on this aircraft, not a cramped one.
Best Premium Plus seats
- 22A, 22L — two windows each, in the middle of a five-row cabin.
- 21C, 21J, 22C, 22J, 23C, 23J — clean aisles.
- 20A, 20L — bulkhead legroom at the window.
Premium Plus seats to avoid
- 24A and 24L — no window. Wall only.
- 24D, 24E, 24F — lavatory traffic behind.
Economy Plus and economy (rows 30–44)
Economy Plus is all of rows 30–34 at about 34in. The first two rows wrap around the accessible lavatory, so the good Economy Plus seats start at row 32.
Best economy seats
- 32A, 32L — Economy Plus with a great window view.
- 33A–33C, 33J–33L, 34B–34K — Economy Plus clear of the lavatory.
- 35A, 35L — the best standard-economy windows.
Economy seats to avoid
- 30B, 30C, 30J, 30K, 31B, 31C, 31J, 32D, 32E, 32F — immediately next to the accessible lavatory.
- 30A, 30L — the exit door takes about 80% of the seat width and the window sits behind the seat.
- Row 43 (A–C, J–L) and 44D, 44F — the rear lavatories.
- 31A, 31L, 34A, 34L, 37A, 37L, 41A, 41L — badly aligned windows.

Frequently asked questions
Do all United 787-9s have Polaris suites with doors?
No. Only the 222-seat Elevated 787-9 has doors. The 257-seat 787-9, still most of the fleet, has the older Polaris seat without a door.
How do I know if my United 787-9 is the Elevated version?
Count the seats: 222 is Elevated, 257 is the older layout. On the seat map, Polaris running to row 17 with no row 13 means Elevated.
Which Polaris Studio should I book?
Row 1: 1A for one traveller, 1D and 1F for two. Row 9 has the same Studio hardware but sits directly behind the mid-cabin lavatories and galley. 1L has the forward lavatory just ahead.
Is Premium Plus row 20 good on the United 787-9?
Not on the 257-seat jet: the bulkhead wall is unusually close and it is the bassinet row, so row 21 is better. On the Elevated jet row 20 is a normal bulkhead.
Which seats have no window on the United 787-9?
5A and 5L on the 257-seat jet; 24A and 24L on the Elevated jet. Several more have badly aligned windows; the seat map marks them.
