Great experience. Typically do klm to Amsterdam but may start taking this flight in future - greatxexperience.

The food was wonderful! The blankets and pillows were a nice touch and the staff were very accommodating, making frequent rounds to offer food, drink, etc. We were also told in advance when to expect meals to arrive, which is thoughtful. I liked the early notification about the lack of headphones as well, although unfortunately I'm not sure we received on for the first leg of the trip, which would have been nice to prepare for. The seats are a bit tight, and the bright monitors on the wall were on during an overnight trip, making it difficult to sleep for those close to them. .

The check in not ok! Demanding that we check our carry ons on check in! When there was plenty of available space inside the plane! And the staff at check- in was rude and not helpful and I was traveling with my autistic son and his service dog! Boarding was easy since we were priority boarding! The crew was ok expect from one guy flight attendant that was actually great!

Crew was unresponsive to request for a soda. Food was horrible and I’d venture to guess many others thought so as well by the amount that they trashed. Made me sick to my stomach and ended up in bed the remainder of the day once we arrived. Screaming child for 3/4 of the almost 8 hour flight. Crew had no headphones whatsoever for free or purchase. Seating way too tight and we upgraded our seats. I do not see us ever flying this airline again.

Standard short hop flight. No food, no entertainment. Just get in, get something to drink, and try to be as comfortable as you can for an hour.

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.

Sat on runway for 1.5 hours waiting on winds to change so we could take off. The pilots did an amazing job getting up in the air when they had permission to take off.

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.
