United Airlines Boeing 787-10 Seat Selection Guide (2025)
The United Boeing 787-10 features the airline's newest long-haul cabins, including the full Polaris Business Class, Premium Plus, and a refreshed Economy cabin. The 787-10 offers one of the most consistent layouts in the United fleet.
However, it is important to note that United's other Dreamliner variants — the 787-8 and 787-9 — feature different cabin layouts, Business Class generations, and seat structures. Seat selection varies significantly between these three aircraft types.
This guide focuses specifically on the 787-10.

1A. United's 787 Variants Explained
United operates three different Dreamliner variants, each with significant cabin differences:
| Aircraft | Business Class | Premium Plus | Notes |
|---|---|---|---|
| 787-8 | Older Polaris (retrofit ongoing), some non-Polaris aircraft remain | Partial PP rollout | Smallest Dreamliner; most variation |
| 787-9 | Polaris (mostly retrofitted) | Yes | Multiple sub-layouts; seat counts vary |
| 787-10 | Always Polaris | Yes | Most consistent & newest layout |
Why this matters:
Seat recommendations, best rows, and cabin size differ across the three models. The guidance in this article applies only to the 787-10.
2. Cabin Layout Overview
| Cabin | Rows (approx.) | Layout | Notes |
|---|---|---|---|
| Polaris Business | 1–11 | 1-2-1 | 44 seats, all with direct aisle access. Lettered A — D F — L |
| Premium Plus | 20–22 | 2-3-2 | 21 seats. Quiet mini-cabin. Lettered A C — D E F — J L |
| Economy Plus | 30–34, plus 42 and 44D/E/F | 3-3-3 | 54 seats at 34" pitch. Row 42 is the exit row and 44D/E/F is the centre-block bulkhead |
| Economy | 35–60 | 3-3-3 | 253 seats total in the Economy cabin at 31" pitch. Lettered A B C — D E F — J K L. No row 41; rows 40, 42 and 43 have no centre block |
Row structure is consistent across the 787-10 fleet.
3. Polaris Business Class (1-2-1)
Highlights:
- Direct aisle access
- Large footwell (bigger than 787-9)
- Full privacy shell
- Memory-foam bedding
- Elevated IFE
The cabin uses a staggered 1-2-1 layout where seat positioning alternates by row. In odd-numbered rows (1, 3, 5, 7, 9, 11), window seats are closer to the window and centre pairs are positioned next to each other — ideal for couples. In even-numbered rows, window seats are closer to the aisle with less privacy, and centre seats are further apart.
Best Seats in Polaris
| Category | Seats | Reason |
|---|---|---|
| Best Overall | 3A / 3L and 9A / 9L | Two aligned windows each, shell hard against the fuselage, no lavatory or galley alongside |
| Best Solo | Odd-row windows: 3A/3L, 7A/7L, 9A/9L, 11A/11L | Closest to the window, maximum privacy. 11L has the best window alignment in the cabin |
| Best Couples | Odd-row centre pairs: 1D/1F, 3D/3F, 5D/5F, 7D/7F, 9D/9F, 11D/11F | The two centre seats sit side by side in odd rows (the centre letters are D and F — there is no G on this aircraft) |
| Best Solo in the centre | Even-row centre seats: 2D/2F, 4D/4F, 6D/6F, 8D/8F, 10D/10F | Separated by the console, so no neighbour beside you |
| Quietest | Rows 7–11 | Mid and rear cabin, clear of both galleys and of the row 1 lavatory |
| Avoid | 5A / 5L | No window at all — solid fuselage alongside. Everything else about the seat is normal |
| Avoid | 6A / 6L | One badly offset window and the shell sits inboard, so neither private nor well lit |
| Caution | 1A / 1L | Wider bulkhead footwell, but bassinets mount at both, and 1L also has a lavatory immediately forward |
| Caution | Even-row windows (2A, 4A, 8A, 10A and L) | Shell set a console-width inboard toward the aisle, so less private than the odd rows |
4. Premium Plus (2-3-2)
Best Premium Plus Seats
| Category | Seats | Reason |
|---|---|---|
| Best Overall | 21A / 21L | Two aligned windows each, full recline, floor storage, and clear of the bulkhead row's lavatory traffic |
| Best Solo | 21A / 21L | Window privacy and 38" pitch, with only one neighbour in the two-seat pair |
| Best Couples | 21A/21C or 21J/21L | The two-seat pairs are A+C on the left and J+L on the right (this cabin is lettered A C — D E F — J L; there is no B, G or K) |
| Quietest | Row 21 | Lower traffic than the bulkhead, and no bassinet position alongside |
| Avoid | 20A / 20C / 20J / 20L | Lavatory door immediately forward of all four, plus bassinets at 20A and 20L. The bulkhead legroom is real, but so is the queue |
| Avoid | 20E | Bulkhead middle seat, and a bassinet mounts at this position |
| Better than expected | 20D / 20F | The bulkhead wall only covers 95% and 90% respectively, leaving extra stretch room to one side. Lavatory traffic forms ahead, but no door is directly adjacent |
| Caution | 22E | Last-row middle seat. The rest of row 22 is fine — bassinets sit behind in Economy, so some infant noise carries |
5. Economy Plus (Extra Legroom)
Best Economy Plus Seats
| Category | Seats | Reason |
|---|---|---|
| Best Overall | 30C / 30J | Bulkhead aisles where the wall only covers 5% and 10% of the seat width, so both feet stretch clear. The best Economy seats on the aircraft |
| Best Sleep | Window seats 31A/31L and 32A/32L | 34" pitch, aligned windows and full floor storage. Skip 33A/33L — the window is badly offset there |
| Best for Tall Travellers | Exit row 42 — 42B, 42C, 42J, 42K | The exit row is 42, not 40. Big legroom and nobody reclining into you. Avoid 42A and 42L, which have no window at all |
| Also Economy Plus | 44D / 44E / 44F | The centre block restarts at a bulkhead here with Economy Plus legroom. A bassinet mounts at 44E |
| Avoid | 30B / 30E / 30K | Bulkhead middle seats, and all three are bassinet positions |
| Avoid | Centre seats (B, E, K) | Least comfortable. Note the Economy letters run A B C — D E F — J K L; there is no G or H |
6. Economy (3-3-3)
Best Economy Seats:
| Category | Seats | Reason |
|---|---|---|
| Best Overall | 48A / 48L and 55A / 55L | Perfectly aligned windows in the rear cabin with no lavatory or galley alongside. The best standard-Economy seats on the aircraft |
| Best Legroom | Exit row 42: 42B, 42C, 42J, 42K | Economy Plus legroom with nobody reclining into you. 42A and 42L have no window — the door 3 exits intrude across 85% and 80% of those seats |
| Best Economy Plus | 30C / 30J, then 30A–30C and 30J–30L | Bulkhead at 34" pitch. The right-hand block is J K L, not H J K |
| Open outlook | 43A / 43L | Two aligned windows, and with no centre block in front of row 43 the cabin feels far more open |
| Quietest | Rows 31–37 | Forward Economy, clear of both the mid-cabin lavatories and the rear galley |
| Fastest Exit | Row 42 | Sits at the door 3 exits, the mid-cabin doors on this aircraft |
| Avoid | Rows 38 (D/E/F), 39 and 40 | The mid-cabin lavatory bank sits immediately behind. Every seat in rows 39 and 40 backs onto a lavatory door. Rows 40, 42 and 43 also have no centre block at all — that space is the galley and lavatory complex |
| Avoid | Rows 58, 59 and 60 | Rear lavatory doors immediately behind. Row 59 loses its A and L seats as the tail narrows and row 60 is a centre-block-only final row with restricted recline |
| Note | There is no row 41 | The numbering jumps straight from row 40 to row 42 across the door 3 area |
| Caution | 33A/33L, 36A/36L, 47A/47L, 50A/50L, 54A/54L, 57A/57L | Badly offset windows — you get a wall panel where the view should be |
7. Known Quirks & Notes
| Issue | Details |
|---|---|
| 787-10 = United's newest long-haul aircraft | Most consistent layout |
| Other UA 787s vary | Important for seat planning |
| Bassinet positions | Polaris 1A and 1L; Premium Plus 20A, 20E and 20L; Economy 30B, 30E, 30K and 44E |
| Row 41 does not exist | Numbering jumps from row 40 to row 42 across the door 3 exits and the mid-cabin lavatory and galley complex |
| No centre block at rows 40, 42 and 43 | D, E and F do not exist in those three rows — that floor space is the galley and lavatories. The centre block restarts at a bulkhead at 44D/E/F |
| The tail narrows | Row 59 has no A or L (B and K become the window seats) and row 60 is a three-seat centre-block-only final row |
| Seat lettering | Polaris A — D F — L, Premium Plus A C — D E F — J L, Economy A B C — D E F — J K L. There is no G or H anywhere on the aircraft |
| Economy is wider than typical 787 | 17.1" seat width at 31" pitch (Economy Plus 34") |
| Polaris has no door | Privacy shell only. No Bluetooth audio and no wireless charging either — 110V AC and USB-A |
8. Best Seats Summary
| Cabin | Best Seats | Why |
|---|---|---|
| Polaris | 3A / 3L, 9A / 9L | Two aligned windows, shell hard against the fuselage, no lavatory alongside. 1A/1L have the wider bulkhead footwell but take the bassinets |
| Premium Plus | 21A / 21L | Two aligned windows, 38" pitch, full recline and floor storage — and clear of the lavatory doors that sit in front of row 20 |
| Economy Plus | 30C / 30J | Bulkhead aisles at 34" pitch with only 5% and 10% wall coverage, so both feet stretch clear |
| Economy (legroom) | 42C / 42J | Exit row 42 with big legroom. Skip 42A and 42L — the exit doors leave those two seats with no window at all |
| Economy (window) | 48A / 48L, 55A / 55L | Perfectly aligned windows, mid rear cabin, nothing adjacent |
