Condor's computers do not work. They do not leave enough time to catch a connecting flight. Condor had to book passengers on a different airline to make their destination. They lost my niece and nephew's luggage. The bathroom had pee all over it before the flight took off.

Condor's computers do not work. They do not leave enough time to catch a connecting flight. Condor had to book passengers on a different airline to make their destination. They lost my niece and nephew's luggage. The bathroom had pee all over it before the flight took off.

Awful!! We got stuck in the passport line for two hours. Condor acknowledges that the lines are really long but says it is not their problem and would only rebook us in two days. We are stuck in Frankfurt for two days and it cost us $500. Condor stated that they gave us a 1.5 hour layover which was more than enough time and in the next sentence said, yes we know the lines are a problem.

I used Kayak.com to buy plane tickets, which sent me to Underpricer. Immediately upon buying the tickets I started getting phone calls telling me that my "tickets were not guaranteed" unless I paid more money. I told them that if they've sold me on just the idea of a ticket, and not an actual ticket, then refund my money immediately. We argued, but they eventually said they would do that. They didn't, I refused the charge on my CC, the CC company eventually charged me anyway, and Underpricer still didn't cancel that ticket because I kept getting alerts to get on that flight. In complaining to Underpricer, they insist that it's my fault and that the most they can do is refund the fees. This company is using deceptive practices and harassing people, and the company needs to be banned from Kayak and from doing business in the US.

Premium economy meant only extended legroom and when the passenger in front of me leaned back, I lost the little space I paid for. Food was not great. Movie selection is okay. Feels somewhere between a mainstream and a budget airline.

The jet is quiet but the food is uneatable and the new seats are horrible .One cannot find comfort on them. When do airlines learn that there is a better service for your clients. Go to a flying wing design save fuel offer a human seat where your arm does not interfere with your neighbor . Provide food that tastes good and offer free drinks

Horrible. Another delayed flight. So cramped! Poor food. So many unnecessary announcements.

One of the female flight attendants had an attitude. The snack toward the end was pretty bad. My husband and I were both sick the next two days.

It was freezing cold, the flight delayed and then I got rebooked to a different connecting flight with a four hour waiting time even though I would have easily made my initial connection

The flight was fine. The food was much better on the second flight. I have NEVER paid for a carry on bag on a zero economy flight booking. I'm very dissappointed about that, and will never fly Condor again.

Great flight, nice options for food and beverages. Fairly comfortable seats for a large person
