Not good. We returned on united airlines and the food was horrible.

The return was painful because of the flight that was canceled. Nobody was able to help us out. It took hours and a lot of walking on two different airports to get a new flight

The cabin was warm and few used the blankets. I should’ve upgraded.

The plan was delayed for takeoff by an hour, but we ended up making the landing on time which was a nice surprise.

The crew was very friendly and nice! Very smooth flight.

The whole experience was positive. Crew very friendly and helpful. Very greedy with pre-seat allocation. Web site too complicated

The meal was wonderful and strawberry ice cream was a plus.

Absolutely amazing! Best airline i have flown with, huge difference to United!

All the flight to USA were arranged to E terminal whereas from Dubrovnik arriving on Zurich is on A80, have to walk all the way from A to E, even need transfer bus , for short transfer time like in an hour, we have to work fast, as soon as arrived at E, it is about time to boarding, pretty tight schedule, I hope Zurich airport can make some rearrangement so that transfer people do not have to walk long way. For short transfer time people, such as 50 min, this is even impossible if still like this.

...as stated previously, red tape should be shorted by Swiss in terms of generating refunds...

Helpful crew in a comfortable and well designed aircraft. My kids also loved the striped design of the airplane.

The return flight, the food was better. Didn't like that even at checkin we still had to pay when only 5 seats were available. Had to pay or would be stuck in the very middle between two others. I had to pay for an aisle and a middle seat. Both were considered prime seats but the two other middle ones were not.

There was one flight attendant who was exceptionally rude about the fact that they didn’t have any meatless options left when I told her I was a vegetarian. The boarding process was a bit disorganized and unclear but everything else was very good.

Seats are not comfortable. Some of the food was good and some not so good.

Really, nothing. I flew economy, and received a very good economy experience.

Flight attendants were polite but not attentive. They did not clean cabin throughout trip, and the airplane upon disembarking looked disastrous! Garbage everywhere ! The state of the cabin did NOT leave passenger with a ‘cared-for’ feeling. It looked a total mess. They also closed themselves off in the back of the plane and passengers felt like they needed to knock to get a glass of water. Very dissppointing.

Seats were not comfortable, and the problems started when we landed at Frankfurt airport. We waited more than 3 hours to collect our luggage, as a result we missed the connected train to Brussels. Our plans for the trip were ruined that day.

I missed my connection in Frankfurt and was booked to another flight to New York. Different destination and got downgraded from Business Class to economy. No Support from Condor at all. Very Bad experience

Flight 1.5 hours late; missed connection. Ground support for rebooking inadequate to the point of ridiculousness.

Flights delayed, and not communicated to the level I accustomed to by other airlines. The crew seems to be hating their job and it shows. It costs you nothing to smile and be a bit more friendlier. Also, no jet bridge, passengers have to use stairs, which is hard for my elderly parents. What's the point of ordering wheelchairs?
