The crew was very helpful and friendly. Food was good. The only issue was the legroom -- not great. The seat in front is also too close to see the entertainment screen properly.

The crew was very helpful and friendly. Food was good. The only issue was the legroom -- not great. The seat in front is also too close to see the entertainment screen properly.

Everything was perfect. I would’ve liked better selections for entertainment, but I slept most of the time, so it wasn’t really an issue.

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

They lost my luggage and there is no update, no luggage and no hope that they will find it. It has been 26 hours since we landed

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.

A Lufthansa flight operated by SAS with a jettime plane. Fight was nice, no food but free tea and coffee.

Good food, overall very comfy. The flight was full so obviously not optimal, but it is what it is.

I tried both on line and by calling the Customer Service line to arrange for a special meal as i have food intolerances. I was under the impression from your service representative that I was successful. I was not. I cannot eat spicy foods and get very ill if i eat bell peppers. I could not eat either menu choice and no special meal was actually ordered. ( your representative tried to order it for a flight that did not have meal service!!! - found this out later). Your wonderful cabin crew managed to put together a fruit, salad, roll and cheese tray for me so I had something to eat. WHY WOULD YOU SERVE SPICY FOOD, WITH NO MILDER OPTION,ON AN INTERNATIONAL FLIGHT???

I liked Quiet people around me. Crew could have helped people with overhead luggage so they aren't moving other peoples bags around and causing problems for people that had there bags there first

The plane was delayed by two hours in Chicago which led to us missing the next flight. Lufthansa rebooked the flight and booked us a hotel for the night in Frankfurt. The level of customer service and getting us taken care of was superb. The flight crew and the service on the ground was superb.

The row of seats were so cramped it was difficult to get in and out of your seat. I even upgraded. A long flight and sad accommodations 😵‍💫 the shorter flight was very comfortable and the seating was spacious

I have flown with many airlines. My first time was several years ago. Now I remember why I avoided them for so long. Lufthanza is the only airline who has ever raised a size/weight issue with my modest standard size carry on. I had to repack three times to meet their carry-on weight criteria. (Apparently the rules of physics apply differently on Lufthansa flight than on other airlines.) In the meantime their staff was quite rude, repeating meaningless phrases like "Rules are Rules." And ignoring the additional fact that weight is also weight, whether it is in found in your carry on or in your suitcase. They eventually acknowledged that customer service and satisfaction is, for them, a low priority. Never choosing Lufthansa again.

They are professional. Nice crew. Still flying Boeing 747. Thank you for that. I love this airplane. Traditional.

The seats were extremely uncomfortable. I spent €25 on internet and never gained access to it. A flight attendant told me she would file a complaint/report on my behalf but it put me in a very difficult situation.

Boarding was easy and well organized, Breakfast was not very good.

Seats much smaller/less leg room than united from Phx. Biarding was very poor and unroganized.
