There is nothing to like about Finnair. Zero service, a mediocre aircraft even though it's an Airbus A350-900 it does not have individual fresh air vents which obviously must be a Finnair option when ordering as Qatar Airways A350-900s do indeed have ................ but they ARE a 5* airline and Finnair is very much NOT. Full flight, no A/C running and as I said no fresh air vents, so it was very stuffy and uncomfortable. I had chosen my seat, as I am a fellow One World member (Qatar Airways Gold member), and isolated myself. When I made check in I looked again and repositioned myself, because obviously Finnair doesn't value my OW tier, and yet when I reported to the desk they had re-assigned yet me another seat sat next to a 'mini-whale' - so poor passenger seating allocation. To give a comparison - flew on a very full A380 QR003 DOH-LHR just 3 days earlier and I was informed by cabin crew that there only about 4 empty seats on that flight and yet 'one of those' was next to me !!! That is how you treat a Gold Member .... but not Finnair.
