We had 2 short flights, within Finland, with Finnair and they were both very pleasant. Our 2nd flight was cancelled due to weather but they rebooked us on a flight leaving a couple of hours later. They board the plane section by section and were very strict about that, so boarding was hassle free even on the second completely booked flight. Due to weather issues at our destination, we spent some time on the plane unable to leave, but the captain kept us updated on the delays regularly and the flight attendants offered water. All in all it was a good experience with Finnair.
If you can get an exit row, it is worth the extra cost for the extra legroom.
