No crying babies the whole flight would be nice. Impossible to sleep. No free snacks , only the main meal

The crew was amazing. Our seats was not very clean and even that was not a full flight but our seats was right beside the WC which did not let us to have a moment of rest.

Excellent service, and came on time! Thank you for your dinner that was chicken with salat/, and 🍰 it was good quality food , the breakfast was very good with good cheese , butter,etc and the tea was very good quality. The space where I was seat was nice so I could stretch my legs. I dit not have the bread as I am in a keto died. Have great time everyone in Scandinavia airline.

The first flight was delayed. We missed the second flight, which was rebooked 9 hours later. We missed all our arrangements for the first day of vacation.

Old plane, food not that great - lacked taste. Crew was nice but strict.

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.

I really enjoyed how clean and big the aircraft was, as well as how friendly the crew was.

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 WiFi wasn’t working, so no one could watch any entertainment for 5 hours. The plane also was delayed and did not leave, nor did the staff prioritize those with connecting flights to de-board first. Everyone with a connecting flight to Munich missed their flight by 5 minutes. Then the next flight to Munich was 14 hours later. The airport could not compensate us because the closest hotel was about 2 hours away. This did not seem like the truth. I was not pleased with this traveling experience.

I paid for our seats and when we boarded and went to our seats it was the last row. I would have never paid for my seats knowing I’m sitting in the last row. The airline must have moved our seats and I didn’t realize it when we checked in.

I had no idea that my ticket only paid for my right to get on the plane. They charged me $130 for my carry-on bag because it was 1 inch too big she claimed but it wasn’t! Then they wanted another fee for everything. I had no idea that Icelandair had changed to such a bargain basement airline. I was very disappointed.

The staff was kind and helpful. There was no food, and you needed to bring your own earphones to use the entertainment, which I didn’t know.

Iceland air transfer was bad. They lost my luggage and I just received it 11/1

Seat was hard and uncomfortable and the temperature too warm and uncomfortable.

Everything was good. Only issue comes from being vegan and flying. The food options are super limited.

Overall good for an economy fare. IMO the movie selection could be improved. Great that you can now connect bluetooth headphones to the entertainment system.

7 hours 15 min flight from SEA to Iceland with no inflight entertainment and no power to charge your own devices, also no meal service, not even any snacks/cookies. You have to buy food and the options are extremely limited (i.e. ham and cheese sandwich and spicy cup noodles). I didn't think Iceland air was a budget airline, maybe I was wrong, the cost of the ticket didn't feel like it though.

Very nice flight, easy connections in Keflavík, and friendly crew.
