Upon departing and landing, the man seating in front of me had his seat leaning back. Taking off nobody told him anything. Landing someone from the crew said something but the passenger ignored him and nobody followed up. Felt a bit unsecured. If this that is some of the basics are missed, what else was overlooked?

On time, reasonably comfortable for economy, decent food. All in all a very good experience.

Every flight got canceled or delayed. Customer service was awful.

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.

The two transatlantic flights we took on Scandinavian, between Los Angeles, and Copenhagen, were significantly less enjoyable than other SAS flights we have taken, particularly within Europe. The flight attendants seemed overworked. There should have been more attendants servicing the plane. The food was particularly disappointing. Lettuce on the salad was frozen. A snack of a tikka masala pita was less than tasty. The flights did leave and arrive on time.

They lost my luggage and can’t find it. My trip is ruined. Online tracking of lost luggage doesn’t work

Flight attendants were attentive and friendly. Enjoyed the peppered shrimp snack. Check in was easy. Only negative was the time it took to get checked luggage, but that was the slowness of CPH staff.

Better food; taste, portion. Bottle of water per seat was great.

Excellent business class seats, service and food. No airline does it better.

The only negative thing was boarding a Copenhagen-bound flight in Toronto. The middle aged woman at the desk gave me some bad time, claiming they wouldn't allow me to board the flight, switching to russian in the process. After I asked her to speak English and explained her that I had to reroute with the airline due to flight cancelations that where beyond my contro and will be leaving the Shengen zone promptly, she told me I had to check in my small bag because the flight was full and they needed someone to give up their cabin luggage. After I refused, she told me she would have to check my bag if it fits the allowed dimensions, which it did. I understand she's not an SAS employee, I understand she needs to check the documents and also make sure there's enough room for overhead bags on a plane. What really made me mad was her hostike tone and the beyond poor communication skills. Basic politeness would go a long way.

Although our departure (DUB) was slightly delayed we reached our destination (LBA) ahead of schedule. The price was very competitive too (around €100 return). Plus, the departure times for both legs were very good: 13:05 and 15:10, respectively. I gave a neutral rating for Food and Entertainment because I didn't avail of either.

Just pushing back from gate now. Boarded into fourth aircraft with 13 hour delay to scheduled departure. Crappy experience.

Notified as to why there’s a delay with our flight.

On time departure; arrived early into Faro. Air Malta operating flight, crew friendly and efficient.

I need assistance and I could not fault it at all. I suffer anxiety and I was always put at ease by assistance staff, and the banter was good. On board the staff was so very nice and kind and showed empathy. Thank you to them. It was my first time travelling since I lost my husband and was so grateful to them.

Buy-on-board through the app is a great feature!

Flying from Newquay was an absolute dream! Would 100% recommend flights from there!

From boarding to disembarking, the whole operation was very efficient.

They were extremely unprofessional and unhelpful at check in. They did not understand laws related to Spanish residents flying with family It was very discriminatory the way we were treated.

They boarded us but somehow did not manage to record us boarding, so rather than check if we were onboard they removed our bags from the aircraft. I got a call from Ryanair staff in Dublin when I landed in Madiera asking me where I was!!! When I said I was in Madiera I was told what had happened. Our bags were to be sent to Madiera the next day via Manchester, they didn’t arrive. They are now due to arrive two days before we leave. I don’t see myself using Ryanair again unless I am forced to and even then I may just refuse.
