Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

The food was terrible especially for a 15 hour international flight. The crew was unpleasant as well.

Really low quality food especially for an international flight. The crew also was surprisingly unpleasant except couple of ladies. I know we were not in first class but that’s no reason to treat customers as less.

Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.

Quick check in. Everything went smooth. I don't know what can be done about airline food.

Crew was good. The reservation got mixed up and they didn't have my TSA number. I am also a Silver Medallion and wasn't able to use Sky Priority.

Delta made it easy, comfortable and timely. The crew was fantastic.

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

Nothing special. The crew never went out of their way for anything.

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

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.

Love thiscsirlibe. So civilized and kind. Good food. Good treatment. On time. Excellent communication.

Online check in of SAS is very poor. Even the kiosks at London had system problems. Either it would print boarding tickets or luggage tags. Many other customers had problems . SAS staff was good and helped.

No choice of food. Needed to pay more even for a can of coke!!!

It was great, used to fly them a lot back 20 years ago but since did KLM as my flight route changed, but very happy with my experience and will come again!

The seats were really close together and hard to get comfortable. The food was okay. The cheese was amazing! I loved the cold towels they gave us.

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