No, it does not work this way on TK. Unless there are good operational reasons, the flights will not be cancelled. There are too many connecting pax on these flights. Can you imagine the nightmare it will be to rebook pax? - so random flight cancellations are not going to happen.

Book the flight from Nevsehir and in the unlikely event that your flight is cancelled for some reason, ask to be rebooked from Kayseri the next day.
