Food could have been better. My pasta was microwaved into a solid block. Inedible.

Food could have been better. My pasta was microwaved into a solid block. Inedible.

SAS is very good at service, the lounge was great, and flights were on time. Boarding is fast and efficient!

No TV screen, free WiFi or power outlets, but seats were comfortable, food and drinks were great, service was awesome!

Very difficult to clearly hear the dialogue on videos due to airplane engine sound. Flying to Copenhagen audio was very clear. Food was excellent. Returning flight--Lunch and breakfast food was the worst I've experienced. Audio was terrible. Why the difference?

You changed our seats without letting us know. We booked two seats on the side of the plane including an aisle, but you ended up putting us in between two other people in the middle of the plane. My husband is 6' 6" and I'm 5' 11", so we need an aisle seat. We were able to move thankfully because the flight wasn't full, but I had to ask the stewardess. You also didn't give us a meal for several hours on the return flight, and it wasn't great (toast with olive/cheese). Finally, you lost our checked bags in Copenhagen so we had to wait an hour after we arrived before we realized they weren't coming. We put in a claim so hopefully we'll still get them.

The check in not ok! Demanding that we check our carry ons on check in! When there was plenty of available space inside the plane! And the staff at check- in was rude and not helpful and I was traveling with my autistic son and his service dog! Boarding was easy since we were priority boarding! The crew was ok expect from one guy flight attendant that was actually great!

Crew was unresponsive to request for a soda. Food was horrible and I’d venture to guess many others thought so as well by the amount that they trashed. Made me sick to my stomach and ended up in bed the remainder of the day once we arrived. Screaming child for 3/4 of the almost 8 hour flight. Crew had no headphones whatsoever for free or purchase. Seating way too tight and we upgraded our seats. I do not see us ever flying this airline again.

Standard short hop flight. No food, no entertainment. Just get in, get something to drink, and try to be as comfortable as you can for an hour.

Travelling coach, comfort is all in one's perspective. Movie choices were great. Food was OK. Flight crew were pleasant. Tip: If they come through asking if you want tea or coffee, do not ask for water. They get miffed. So use the call button after they pass through.

Cancelled my flight. Only option had a layover in Italy. No compensation for the 4 extra hours of travel time. The travel agency, cheapflightfares, blamed Scandinavian airlines and said there was nothing they could do. Scandinavian airlines said since it was booked through a travel agency there was nothing they could do. The entire thing was incredibly frustrating. Never booking through kayak or with Scandinavian again.
