The flight left 1.5 hours late but there was no information about the delay. My business class cabinet had two small children who cried much of the trip. Service seemed rushed.

The flight left 1.5 hours late but there was no information about the delay. My business class cabinet had two small children who cried much of the trip. Service seemed rushed.

I didn't like breakfast, I prefer plain rolls with butter.

Part of our luggage was lost and we had to wait 48 hours before receiving it. Also someone had to wait in the hotel to get it!!! Frustrating & disappointing

Could have a friendlier crew. The entertainment should be updated to be more current

The attendants were nice, but I was freezing the entire nine hours and so cramped. Please provide more blankets or make it known how to borrow a blanket for such a long flight. Even in already expensive economy class, people really need a bit more leg room and two more inches between seats to comfortably fly for 9 hours. Our family works very hard, but the extra expense of economy plus is just not in a lot of customer's budgets, and we still want to fly in equal peace and comfort. Please create future aircrafts that reveal reasonable care for us, the cramped- to- death customers more than the question of "how can we jam a few more human beings into this already cramped flight to impress our higher ups making a few more dollars. It's just Wrong. People need a reasonable amount of leg room and a blanket when the airline attendant said the extreme air conditioning could not be turned off. The food was tasty, but a bit more protein and less fluff would be appreciated. Thank you.

It was very good! Crew was very friendly, food was very good. I was on economy so the comfort was ok. Other than that, I would fly Condor again!

Breakfast was terrible. Sugary yogurt, inferior pastry, poor quality fruits. No protein.

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.

Not a valued customer..just a herd of cattles that is being shuffled around. Employees just lie into your face. Last time I flew with LH companies. No customer service at all. The customer is their enemy.
