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.

I got scammed. The flight I booked did not exist. The flight was suspended more than a month ago & I did not get any notices or e-mails. When I arrived the airport there is no flight, no people working. I'm trying to get a refund, but they said they are not sure I can get full refund. I booked the partnered-agent called Chatdeal. You guys need to drop these people from listing on Kayak, they are completely scammers.

The flight was great. The flight crew were all gorgeous women who were very helpful. The seat situation is not as awarsome but only because I’m a 6’8” giant!
