About this cabin

United Airlines' 777-300ER in this configuration seats 350 (J/W/Y/Y/Y/Y). This is our best current estimate for this layout, built mainly from secondary sources — treat exact seat-by-seat detail with a little more caution than usual. United Airlines flies only this one cabin layout on the 777-300ER — no version lottery on this type.

Quick pick, by traveller

If you're…PickWhy
Travelling solo2AA window seat rated highly with nothing working against it — lean on the wall, control the shade, nobody climbing over you.
Travelling as a couple2BThis row's layout puts a genuine two-seat pair here — no middle seat exists in this group, so it's just the two of you.
Tall passengers33BGenuine extra legroom that also still reclines — not every extra-legroom seat does.
Nervous flyers33BOver the wing, close to the aircraft's structural centre of gravity — the smoothest ride on board when it's bumpy.
Trying to sleep2AA window seat away from galley and lavatory traffic, so aisle lights and trolley passes are less likely to wake you.

Known quirks on this aircraft

  • Seat doesn't recline (36 seats: 19A, 19B, 19C, and 33 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, 17A, 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: 15B, 15C, 17B, 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 (42 seats: 1A, 1B, 1C, and 39 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 (16 seats: 33A, 33K, 34A, and 13 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.
