My experience with Corendon (Dalaman to Cologne, 8th of September) was quite disappointing. We were forced to pay an extra €60 for baggage, the online check-in was not available which caused unnecessary hassle, and yet they still charged us for the in-person check-in. To make matters worse, my seat ...

Corendon Airlines is hands down the worst airline I have ever flown with. They charged me €20 (₺ equivalent) at the airport, claiming I didn’t complete the online check-in.
