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..

The crew was friendly, the flight was pleasant. Thank you for your service!

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.

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...

Amazing! Everyone was so nice and the food was so good!!

Terrible customer service. The flight attendants were rude. We experienced significant turbulence for a large portion of the flight and there was very little check in from the flight deck. The space was extremely limited to the point where it felt like torture. Never again

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

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
