We found our way to the Ukraine Airlines desk and we are given a Turkish Airlines ticket for tomorrow. I fly a lot and I have never had such a terrible experience. 3.5 hours inside a hot plane in 40-45 degrees with no explanation! 24 hrs before the flight got a notification the flight (of 1h 35min) would be delayed for 7 hrs.
No explanation about reasons, though it is required in their internal rules.
Do yourself a favor, take a different airline so you don't have any regrets and an empty pocket. They just don't go further, and the service is painfully slow and disorganized.
