We had a hard time traveling with you. Our flight was scheduled for October 6 at 3:40 pm. We did the check-in immediately after we got the email from Condor. We arrived at the airport 5 hours in advance. Everything seems smooth. It was announced that the boarding will be at the gate B 48. We arrived there in time (before 2.55 pm). When the boarding time came and nothing happened, we double-checked at the screen. There was no update over there. After that, I found an airport employee at the counter and asked about an update for Toronto flight #DE 2402. He said everything is according to the plan with small deleys. We sat down and waited. About 10 minutes later, some airport employee (lady) arrived and announced that the gate was charged to B 43. We immediately headed there. When we got there, it was a huge lineup. We stood up and waited for a couple of minutes. When we got closer, we realised that on the screen is a different destination. I went to the counter and re-asked. The employee answered that Toronto #DE 2402 is on gate B42. When we got there, the employees said that the gate as well as the flight is closed. They intentionally confused us due to overbooking. They lied that they announced about boarding. we stayed 10-15 meters away, and there was no chance we couldn't hear it. We were not alone it was another couple of families with the same issue. Per the time when we arrived at gate B 42, the plan was still visible through the windows. But the employees denied getting us to the board. When we got the Comdor customer service, they provide to us flight for the next day. They apologized for any inconvenience as well as accepted the fault. We really appreciate this solution, but this flight deleys had impacted our next flight in our trip (another 2 plane). When we changed the date for the next day in order to accommodate further traveling, we paid $2500. Also, we $220 for the one stay in the hotel overnight. Also, we missed one day of work. You can do your own investigation and verify that there was no proper communication. We are expecting a peaceful solution when you compensate all our extra spent. All references are attached.
