Cabin specs

Known quirks on this aircraft

• Seat doesn't recline (33 seats: 16A, 16B, 16C, and 30 more) — This is the last row of the cabin, or the row directly in front of an exit, so the seat back is fixed upright for the whole flight.
• Often cold or draughty (18 seats: 1A, 1D, 14A, and 15 more) — Seats next to a bulkhead or door on a long-haul widebody are usually the coldest in the cabin — bring a layer for this one.
• High foot traffic (42 seats: 12B, 12C, 14B, and 39 more) — This aisle seat sits right next to a lavatory, galley or exit, so expect a steady stream of people brushing past, especially early and late in the flight.
• No underseat storage (36 seats: 1A, 1B, 1C, and 33 more) — Bulkhead and exit-row seats have nothing in front of the seat to store a bag under, so your bag must go in the overhead bin for the whole flight.
• Wing blocks the view (14 seats: 27A, 27J, 28A, and 11 more) — The wing sits directly outside this window, blocking most of the view — but you also get one of the smoothest, quietest rides on the aircraft.

Frequently asked

How many seats does United Airlines' 787-9 have in this configuration?

257 seats in total, arranged as J/W/Y/Y/Y/Y. This is one specific configuration — United Airlines' fleet may include other configurations of the same aircraft type, covered below.

Is this the only cabin layout United Airlines flies on the 787-9?

No — United Airlines flies 2 different cabin layouts on the 787-9, roughly 85% of the fleet for this one. Check your specific flight's aircraft registration where possible, since booking the same route twice can put you on a different layout.

Which seats should I avoid?

Seat 12B in United Polaris is worth avoiding: A galley is directly next to you, so expect crew activity, cart noise and light throughout the flight, especially during meal service. The full seat map marks every seat we'd steer you away from, with the specific reason for each.

Does the 787-9 have wifi and power in this configuration?

Has a real person checked these individual seat scores?

Not yet for this specific configuration. The scores above come from our rules engine, which reasons from real aircraft geometry, but they aren't marked as human-verified until someone has actually reviewed the unusual ones — see the verification section below for the current status.
