Airline reviews

I loved the food. The veggie option was delicious. I also appreciate the sense of sustainability with Airline's choice of packaging. Hosteses were super friendly and courtous. I also appreciate that checked luggage was included with the airfare. The entertainment portal could see some improvements. The touch screen responsiveness in Solitaire game was poor and it doesn't seem to be hardware related as other screen functions were just fine. It was hard to move cards between piles and system skipped cards from the deck. Also, there was no option for winnable vs random draw. Sudoku was cumbersome regarding touch screen, too. In addition, the difference between medium and difficult levels in Sudoku was huge. Medium was actually too easy.

This was my return flight and it was 100% different than my out bound. Better seats and great food for sure. As i was disappointed last time but this time they made up for it

Flight was good but the passport control in airport for outbound passengers was a mess, fortunately they pulled passengers making connections to this flight for expedited processing so we made the connection.

My daughter always gets sick when we order the gluten free meal option. Internet didn’t work as advertised.

The flight was very cold, and the seats were rather uncomfortable. The food has been better on our other SAS experiences. Most significantly, the luggage with most of my wife's personal items and clothes didn't make the flight. Hoping for a quick resolution, but no real opportunity to speak with a Human has us concerned.

It was so hot on the plane. No air jets above the seats

Please see my comments for the flight from Chicago to Copenhagen

We were sitting in SAS plus. Super friendly, service that went above and beyond on a Full Flight too! Meals were deliscious and trays were cleared promptly. Generous drinks offered throughout the flight. Would like to suggest better movies on offer to watch.... In all genres and maybe more cooking shows? There was only 1, Nadia's Everyday Baking... Thank you

This was my first time flying SAS and used them for 4 flights. The crews, flight and communication was outstanding. I flew premium economy and was extremely impressed by their SAS lounges. I will 100% ise SAS again. Everyone was so pleasant!

little entertainment choices. Seat/bed too firm an no sleeping mat

Very comfortable plane. The food was very good (for airplane food). The crew was great

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.

It was good. The seats in economy weren’t bad

Very good. Comfortable and I felt well taken care of from start to finish

We were in premium economy seats that appeared to be locked in plae, No reclining. My aching back.

I don’t understand how they charge as much as they do for such a poor experience

I wish the plane had pod seating for business class. I had a window seat (8K) and I had to climb over the person sitting on the aisle when I needed to get up. Also there is no partition between the seats for privacy when sleeping. The Asian airlines have much nicer business class seating. Their seats are wider for better comfort when sleeping.

The seat space seemed small especially when the person ahead reclined but other than that, very good.

Food was poor quality and the screens for entertainment didn’t work properly

Boarding process was late Could do a pre-announcement of flight status.
