I have booked 32J (economy comfort) on A350 HEL-BKK and wonder if I should change this to the seat with extra legroom on exit row (51J).

It will be my first time with finnair economy so I don’t know what the seats are like. I wonder if the the exit row seat can recline or not and whether the armrests are fixed. I can’t find the new finnair layout on SeatGuru either.

I am 178cm tall with a slim/normal build. Any advice will be much appreciated. Thank you!
