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 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.

Very helpful in getting us off the plane first to make a tight connection.

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

Maybe more diverse entertainment. Although the inflight cameras were amazing 10/10

Boarding was chaotic and the flight left late but arrived at a decent time. This may have been because of the sxsw festival that was going on.

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

The flight got canceled and you just send an email in the middle of the night and no solution to how to get on the next flight or provide other solutions.

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.

Missed a connecting flight and SAS was at fault. I was awarded a $20 voucher in exchange for 8 hours of my time? Gfy.
