Very good seat, very comfortable, good food, and good service.

It was a good flight, very comfortable seats for sleeping in business class. Probably the most comfortable business class seat I've ever had (20+ times in business class on various airlines). Service was good, but the only downside is my screen didn't work and it had to be reset multiple times to get it to shut off. I had to block my eyes because the screen was white almost the entire flight and I wore an eye mask when I slept. But when eating and reading in my seat, my eyes hurt because the only way to turn the screen off was reset it and the screen would only be off for a few minutes at a time.

Everything was wonderful! AirBus seats are more comfortable to sleep in as compared to the Boeing planes.

All reviews good because...flight from BWI to London ,economy seats was miserable. I usually book 1,step up from economy but this would have added 1500 bucks 1 way. Bit the bullet and upgraded for retun flight, otherwise all ratings would have been rock bottom.

Great. It was awesome to have boarding from the front and back of the plane as it made the process go very quickly

It was okay. The airplane was a little smaller than a flight from Thailand to Helsinki.

This was an absolutely exceptional flight. The flight attendants were extremely attentive and very friendly. They seemed to go out of their way to make us comfortable and to make sure that we had everything we needed., We were in business and were very happy with the size and the details for our pods. We would definitely recommend Finnair and will definitely be flying with them again.

We had an excellent trip with Finnair. This was our first time and we’re very pleased. The only issue was with the boarding - it was a little bit confusing and needs a little bit of streamlining.

Crew very lovely. Arrived an hour late due to bad weather. We were given new tickets to an other flight but it could have been organised better, so we did not have to run through the whole airport to.

Flight delayed over an hour. They said they would hold our connection but then did not.

I was unable to rebook a flight booked through cheap flights. Could not rebook, despite premium eco.

Fantastic. The only thing - out of my six luggage one was lost in Copenhagen, however it was delivered Home 3 Days later so all great..

Our trip plan from Kayak stated we were flying SAS. That was not true. The first leg was a Delta flight. We wasted 25 minutes before finding out to check in with the correct airline. Then our SAS flight for the second leg arrived 25 minutes late, and our third leg flight with SAS closed the gate knowing the flight delay was SAS’s fault, and that this flight would only be backed up 5 minutes. The final kicker was that between Delta and SAS, they lost all our checked luggage.

Our originating flight into Copenhagen was an hour delayed, causing us to miss our main flight from Copenhagen to the US. There had been snow and we needed to be de-iced, but they seemed very slow getting the flight ready, with no explanation. The delay caused us to be put in with thousands stuck at the airport with an all day wait to get rebooked on a flight 2 days out.

Flight was completely full January 9th? I problem i had the stewardess was bumping into me constantly walking by? very annoying.. on Austrian air I dint have this issue at all...

The flight was very cold, and the seats were rather uncomfortable. The food has been better on our other SAS experiences. Most significantly, the luggage with most of my wife's personal items and clothes didn't make the flight. Hoping for a quick resolution, but no real opportunity to speak with a Human has us concerned.

I was surprised how good an American airline can be - I was really impressed.

Cut out the nickel and dime pricing for "seat selection" and baggage, To do this on an international flight is just mind boggling. Seriously, why treat customers this way??? Nobody wants these hidden extra fees and everybody hates them. Also plane was too warm and no air vent, and water dripped from the ceiling at one point,

It was a fairly old plane in which you couldn't buy an internet connection.

Scandinavian was perfect. Nice A350 with an on time departure and an an experienced crew. What a difference from TAP.
