I just had my first TK experience on the IST-ZRH route. The flight itself was on time, but check-in was something out of a horror movie. I overheard a couple of PAX saying there was a strike, hence the mile-long check-in line at IST. It took 55 minutes to reach the counter. It might have been a one-off and like I said, the flight left on time. I was just happy to be one of those "at the airport two hours before departure" people.
