The first flight was delayed. We missed the second flight, which was rebooked 9 hours later. We missed all our arrangements for the first day of vacation.

Terrible airlines, kept lying to me about the fact that my connection flight was cancelled. Left me hanging until last min. NEVER AGAIN

Cancelled flight, wasn't refunded paid selected seats. Poor customer service. Called airline and they didn't realize the flight was cancelled until several hours after the email notice was sent.

5 of my 7 pieces of luggage are missing and they cant call to find out where it is. I have to fill out a form and wait for them to mail it to me in several days (if they find it). That does not work for my travel itinerary. I need my full ticket cost refunded please.

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..

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

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

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

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.

Business class seats narrower and the most uncomfortable Business class I've ever experienced. Clothes on the seats was itchy, head of the bed was elevated causing us to slude down even though they were "lie flat seats". Plane was way too hot. My partner and I were both sweating just sitting in our seats. Staff appeared sad or depressed
