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.

They cancelled our flight home less than 24 hours before it was supposed to leave. It partially ruined our last day because I was on the phone trying to get 5 people home and the stress that it causes. We still arrived at the airport with no definite flight plans. The actual flight was good but my kids really misses the kids meals I had ordered for them which obviously didn’t make it to the new flight.

The seats were really cramped. The high backs on the chairs made you feel claustrophobic.

Nothing special or negative. Pretty typical flight…no freebies in the way of food etcetera, but none were expected.

They were all bad because SAS was at fault and cost me my time. I will never fly SAS again.

You cost me my time and did not compensate properly. Gfy.

Seat was lumpier than I’ve ever remembered it to be although comfortable when tilted back. I don’t recall being that hungry after being served food from SAS before. Flight attendant on the second flight to Aalborg seemed to be having a bad day.

I experienced trouble with the automatic bag check in. When I scanned the baggage tag I received, things were fine as the conveyor belt moved forward then abruptly stopped! My luggage traveled about 4 feet and I had to reach over a barrier to retrieve it. I went to another scanner position and when I scanned the SAS baggage tag, the screen told me it could not continue!! I went to another scanner position agent who had me put it on the conveyor belt by her & somehow sent it down the belt. I flew from Bergen to Oslo with a two 2️⃣ hour layover before connecting to LHR. My bag was NOT on the flight. I had no clothes for the next day when I flew to Boston. I filed a Lost Bag report and waiting for updates.
