Excellent service throughout. Airport process is quick and easy. Very courteous staff. Great service in the plane! Just outstanding punctuality and service overall!!

I have paid for extra legroom on my flight. My seat was broken and did not recline. The crew could not fix it and refused to provide me with another seat

Over all experience was good. However the connection time was too short at CPG. We missed our connecting flight to AMS as the passport control line was too long and by the time we got our passport control done it was too late I wish there were some SAS staff to help us out at the passport control center Though they put us in a KLM flight from CPG to AMS, That flight was also delayed by over two hours

No vegetarian option was provided for the regular meal or the pre-landing snack.

The Scandinavian flight was excellent, however the second flight was partnered with TAP Portugal which was not so good. crowded gate area with no chairs, delayed flight, bad boarding process, no entertainment system onboard, and the baggage didn’t get to the carousel until well over an hour which caused our taxi that was waiting to leave. Love SAS, hate TAP.

Great logistics and timeliness as we arrived quite early. Flight smooth and fast. Excellent entertainment. Plane itself was a bit tired and the crew mostly indifferent. Baggage took forever but that’s on CPH. Would use SAS again for sure.

Will not recommend SAS for business travel. Food was so-so. Service was very good. First leg was very good. Second leg from Copenhagen to Barcelona was terrible. We paid a LOT for business class and to have seats worse than most coach seats with no entertainment and no charging available for 1/3rd of the whole trip was not acceptable. Very disappointing. I thought they were coming back in the U.S. with style, NOT YET.

I do not have a problem with the airline but both my two suitcases that were supposed to go from Hawaii to Copenhagen didn’t get on the plane in Seattle. I arrive on Monday the 21st at 10:30 in the morning. I did not get my two suitcases before Friday late afternoon that is unacceptable.

No choice of food. Needed to pay more even for a can of coke!!!

The seats were really close together and hard to get comfortable. The food was okay. The cheese was amazing! I loved the cold towels they gave us.
