Airline reviews

Flight was cancelled without notice or any reason given. I found out coincidentally when i was checking the baggage allowance on the app, When contacting the airline, the only option peresented to us meant we lost a day of our weekend getaway. Had a lot of contact with airline prior to flight, trying to get them to resolve the issue. We could have traveled the first stretch ourselves but the airline refused to accommodate this. The airline outright refused to be forthcoming in agreeing to alternatives that would let ut keep the date we had booked, and so a third of our holiday effectively vanished. This meant a lot of hassle, changing hotel nights, activities etc. Furthermore and after the flight, customer service refused to answer our complaint unless we used their very restrictive online form, which gave us no chance to properly explain what our issues were. They have of course denied our complaint, and so i have to bring the matter further. If you have an alternative airline to use, please do. SAS treats its customers as a necessary evil.

Yes avoid JFK airport at all costs. A horror to navigate.

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

Food was underwhelming. One free coke, charged $$ for one wine. Last year one wine was included. And prices were much lower.

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
