Finnair is my goto company when traveling from Norway to Asia. I travel at least 2 trips a year to different destinations in Asia like Japan, Korea, China etc. While they are not on the tier of Qatar/ANA/Cathay etc they are on the tier just below. they also do have more and more of the newer airbus 350 in use on these long haul flights which makes the difference between them and the tier above less noticeable.
On all of these flights you get two meals with free drinks, free water at any time, blanket, a good selection on the entertainment system and the stopover in Helsinki is really fast. Also I did not notice any difference between Finnairs Airbus 350 and Qatar Airways Airbus 350 in regard of seat space and entertainment system (flew both the same year). If not for the different color scheme I wouldnt be able to tell the difference if asked in a blind test. However Finnair also do still use older airbus 330 and these are of course out dated compared to the 350. So sometimes you get to fly the new airbus and sometimes you end up on the older version. This is also one of the reasons Finnair is a tier below ANA/Cathay etc.
However when everything is ok, then Finnair really shines and there is nothing to complain about them at all. They also got great prices to Asia and have a shorter flight time for people traveling from Scandinavia.
But the negative is that Finnair is not always the best at solving customer issues.
They are a bit slow to answer and you sometimes have to be persistent about your rights before they approve. However they have never outright refused to comply to anything that is my right as a passenger and most of the times there are no issues with them at all.
There are also a two incidents I have had where I ended up writing a long complaint after my trip. One was when they left my luggage in Helsinki and it took 5 days before it arrived in Tokyo while they put blame on another airliner.
The good thing is that they seems to understand and tries to make it up to you after wards since after i complained about the entire ordeal they offered my a nice compensation. But all in all their customer service is way better than the likes of Norwegian and SAS, but not quite up there where the top tier airliners are.
But the overall experience for me after using them over 14 times is that they are the best option when it comes to price, service, comfort and flight time traveling from Scandinavia to Asia, and i will use them again.
