budget airline, not a lot of amenities but perfectly priced for a 3.5hr flight. Crew/Pilots were great, communicative, and overall provided a great experience for the price point. Have flown with Norwegian when coming in/out of Norway for the past x10 years now!

budget airline, not a lot of amenities but perfectly priced for a 3.5hr flight. Crew/Pilots were great, communicative, and overall provided a great experience for the price point. Have flown with Norwegian when coming in/out of Norway for the past x10 years now!

Unfriendly staff at boarding gate. Unclear announcement at about gate change. Low cost airline with no amenities on board. Bring your own water.

Terrible communication about cancellation of flight. Put on a flight the day after our departure day even though there were seats the following day

…not even a power outlet. Nothing but uncomfortable seating with unhelpful staff.

Overall flight was fantastic.i really enjoy the whole journey .

Little more legroom would have been nice. But it's a very short flight, so it was fine really.

Short flight, some waiting to board, but no issues and no frills.

No staff at the gate and the flights were not posted on the board so we missed our flight. Horrible experience. Be VERY careful flying Norwegian. Super limited ability to communicate with their slim staffing and restricted hours.

Tickets were cheap but it says no where that food was not included, I travel Austrian, Swiss and Turkish airlines all the time always food is included, never flew Norwegian again

Flight was ok but lack of communication cost me to literally beg to be put on another flight as connecting flight had departed

Over 1 Hr delay. No APU so no AC on ground. Plane was hot during boarding and then they closed the doors over 20 minutes before engine start so interior of plane was steamy hot and stuffy. Could have been helped by opening doors until ready to depart.

Ad experience - been flying many years with them but they are losing out to other carriers with their service and bagage / seating policy. My 2 12-yo kids were not placed with the parent. Absurdity.

Short flight so it was okay. Nice crew, all very pleasant and professional. We were near the back in row 27 so just as we got our drinks, we started our descent so had to drink very quickly!

KLM remains a quality flag carrier airline which maintains its standards whilst all their competitors are lowering theirs.

I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

You should not have to pay for WiFi in business class

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

The flight was cancelled without explanation, and the replacement flight was late

No vegetarian option was provided for the regular meal or the pre-landing snack.

The Scandinavian flight was excellent, however the second flight was partnered with TAP Portugal which was not so good. crowded gate area with no chairs, delayed flight, bad boarding process, no entertainment system onboard, and the baggage didn’t get to the carousel until well over an hour which caused our taxi that was waiting to leave. Love SAS, hate TAP.

1) SAS sent me emails that i could check in but that was just a waste of time because traveling to the us i actually had to check-in at the airport. 2) SAS evidently does not care about vegetarians as it does not offer regular veggie alternatives in the transcontinental flights.

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.

SAS has too many other airliners. They don't need to exist.

Only one choice for meal seats had no leg room

I didn't book special seats but the ones I got were great. The food wasn't good but on par with other airlines

Will not recommend SAS for business travel. Food was so-so. Service was very good. First leg was very good. Second leg from Copenhagen to Barcelona was terrible. We paid a LOT for business class and to have seats worse than most coach seats with no entertainment and no charging available for 1/3rd of the whole trip was not acceptable. Very disappointing. I thought they were coming back in the U.S. with style, NOT YET.

I do not have a problem with the airline but both my two suitcases that were supposed to go from Hawaii to Copenhagen didn’t get on the plane in Seattle. I arrive on Monday the 21st at 10:30 in the morning. I did not get my two suitcases before Friday late afternoon that is unacceptable.
