The staff were great, the food was good. I just hate being crammed in a tuna can for 10 hours cause I can’t afford a better seat.

The staff were great, the food was good. I just hate being crammed in a tuna can for 10 hours cause I can’t afford a better seat.

Baggage was mis-handled; food and grocery items in the baggage were damaged.

It was a good flight. Everyone was professional and the flight was smooth.

SAS has too many other airliners. They don't need to exist.

Service, food was outstanding. They make every effort to make sure that your long flight is as comfortable as possible. The only reason I did not rate them excellent is the way they handled our cancelled flight. They were great about re-booking except for the hotel. A communication breakdown ensued regarding who was booking the hotel for our overnight stay: the city where the flight was cancelled or the city where we were going to lay over for the night. In the end, neither of them did, so we ended up doing it ourselves and were extremely lucky to get a room at all. Given that, I still would not hesitate to fly with them anytime.

I paid extra for our seats on the way coming back from Stockholm to New York the seats were changed and it was totally waved. This happened to three more passengers.

Love thiscsirlibe. So civilized and kind. Good food. Good treatment. On time. Excellent communication.

Online check in of SAS is very poor. Even the kiosks at London had system problems. Either it would print boarding tickets or luggage tags. Many other customers had problems . SAS staff was good and helped.

great crew, professional, funny, and great service. good condition plane too! great experience

When my flight was changed from delays they were quick to rebook me.
