The layover was very long. Other than that, great trip so far

Elderly traveler with disability was bumped from extra legroom to economy with little legroom. He couldn’t bend his knee to fit in the seat. Very uncomfortable for a 7 hour flight and will be reported to DOT. Then the food was disgusting. Boiled chicken with boiled rice and steamed veggies. 3 slices of carrot and one broccoli. We couldn’t eat it. No salt or pepper provided. Disgusting.

Good flight. Mass boarding. Seats fairly comfortable. Food okay although may have upset my stomach a bit.

The crew were nice and courteous. Exonomy seats were worse than expected. Overhead bin space was non existent thanks to loose enforcement of the carryon size and letting passengers put up their purses jackets and backpacks up there leaving no space for others with a small conforming carry on. Food was not good at all. Perhaps worse chicken I ever had in my life. I had to have them take it after tasting how bad it was. Whoever made that should not be in food making business.

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

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

Seat was lumpier than I’ve ever remembered it to be although comfortable when tilted back. I don’t recall being that hungry after being served food from SAS before. Flight attendant on the second flight to Aalborg seemed to be having a bad day.

On this shorter leg and with an older plane, just mediocre. On the connecting long haul (Chicago to Copenhagen) everything was great.

My outbound flight was incredible... Milan to Chicago. The crew worked so well together. Each passenger felt spoiled and incredibly valued. The crew on this flight was fine. Nothing to complain specifically about but could not give top rating only because of the superior crew, hospitality, warmth we felt on the first flight. Unfortunately. You managed to lose my luggage ..my only piece checked in. Lost in Copenhagen so I had the added stress, time wasted to file the report. To make things worse, Italian rail decided to strike that Sunday so I could not take the train as planned back to Switzerland. Horrible waiting time and poor communication for boarding substitution bus. The substition bus to the town of Stabio did not run on time and was late about 40 minutes.

The flight was cancelled early on and messed up the whole vacation and hard to get a refund from Kayak as they owned the ticket and of course they did not believe that SAS cancelled the ticket. Definite bad side to third party. SAS had rescheduled but overlapped the connecting flights. That did not work. Flight was cancelled long ago but Kayak still has it. Like it was taken? Bad IT ? Or all assumptions and no follow up which is the whole IT world. It needs to wake up and be more efficient. Especially as the world is going, there will be no freedom to do anything. And we will be living like the Middle Ages. Yeah, go read up on that while you still can.
