Other than a delay that had nothing to do with the staff, it was a very pleasant experience.

Other than a delay that had nothing to do with the staff, it was a very pleasant experience.

SAS is the representation of the Scandinavian minimalism, which I like. I wished they had a more relaxed policy on free water distribution beyond one bottle (500 ml) per person and two drinks, including water, per overseas flight.

Much better, not their fault but my plane was so delayed causing me to have to take this airline rather than my earlier connecting flight

TERRIBLE! Staff was unfriendly, rude, and demeaning. One flight attendant touched me to grab the complimentary blanket off my neck because I couldn't take it home, while a bunch of other people took theirs home. I have never been so ill treated. I am not happy at all. And flight was delayed, no information until short notice for everything. Lost an entire day at my destination. I expect a full refund for that experience. Never will fly with them EVER again

My return flight has been changed to JFK from EWR without any notice or reason

This was my first time flying SAS and used them for 4 flights. The crews, flight and communication was outstanding. I flew premium economy and was extremely impressed by their SAS lounges. I will 100% ise SAS again. Everyone was so pleasant!

I upgraded to economy plus and it’s so worth the price. The crew is exceptional and the food is pretty decent. I would definitely fly with them again.

They lost my luggage. Tromso in winter without warm clothes is not fun.

The flight was on time and loading was fine. I really disliked that all drinks other than coffee or tea had a cost. Deplaning was also an issue as people did not wait for those in front of them to get out before they pushed forward

Flight was delayed 3 hours. Pilot cancelled flight under 4 people volunteered to change their seats to economy from business class.
