Finnair's own seat map numbers each cabin on this aircraft from a fixed starting number rather than carrying on from the one in front — Business from row 1, Premium Economy from row 20, Economy from row 31, and the rear Economy section from row 51 behind the mid-cabin doors. The numbers in between — 9 to 19, 24 to 30 and 46 to 50 — are not used at all. Finnair does not say why it numbers this way; that reading is ours, from its own drawing.

Quick pick, by traveller

If you're…PickWhy
Travelling solo3AA window seat rated highly with nothing working against it — lean on the wall, control the shade, nobody climbing over you.
Travelling as a couple3DThis 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 passengers31BGenuine extra legroom that also still reclines — not every extra-legroom seat does.
Trying to sleep3AA 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 (11 seats: 23A, 23C, 23D, and 8 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 (11 seats: 2A, 2L, 8A, and 8 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.
  • Narrower than usual (12 seats: 65A, 65B, 65C, and 9 more) — This section is narrower than other sections of the same cabin class on this aircraft, so the seat itself will feel tighter than you might expect.
  • High foot traffic (25 seats: 1D, 1H, 2D, and 22 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 (20 seats: 1D, 1H, 20J, and 17 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.

Frequently asked

How many seats does Finnair's A350-900 have in this configuration?
321 seats in total, arranged as J/J/W/W/Y/Y/Y/Y/Y/Y. This is one specific configuration — Finnair's fleet may include other configurations of the same aircraft type, covered below.
Is this the only cabin layout Finnair flies on the A350-900?
No — Finnair flies 2 different cabin layouts on the A350-900, roughly 44% 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.

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.
