I fly with them regularly throughout Scandinavia and to and from UK.
I've flown SAS Go and SAS Plus - both products are great and do exactly what it says on the tin. Self service check in and bag drop are great and I've never had to wait for a machine to print off a baggage label or subsequently scan the baggage label at bag drop.
I've never had a problem with them either on the Ground or in the Air.
The aircraft are always clean.
Crew very pleasant.
Coffee Strong!
