| This turned out to be a nightmare experience. I purchased the ticket with Turkish Airlines AUH-IST-KSC. Transiting time in Istanbul of 2hrs was sufficient enough - so I thought - to get refreshed, buy a cappuccino and some croissant. Wrong. For some unexplained reason, IST airport started with Security control checks in the transit area. Don't ask me why. I have an aviation background and I failed to understand logic behind this decision. Passengers coming from the airplanes and transiting to another flights are cleared already, but obviously not for IST airport authorities. I understand the high security threat of potential attacks, but to force passengers in the transit area to go through security checks (again) simply doesn't make any sense to me. Especially when the airport doesn't have procedures to speed up the process or to accommodate passengers with shorter connecting times. There were definitely more than a thousand people waiting, waving with their boarding cards, trying to get the attention of oblivious airport staff, chaos everywhere and waiting time approximately 2 hours. There is no process for passengers with short connecting times and staff clearly do not care. When we approached them, it was like speaking to a stone. No interest, no friendliness, no pro-active approach. They told us that this is the everyday case (hundreds of people with short connecting times not being able to make it for their flights due to the waiting times at new security checks) and they don't care, procedure is procedure. I was told that if I miss my flight, I should go back to the Turkish Airlines transit counter and they will help me to get to my next flight. My next flight would be in three days - and only that was the argument that finally counted and someone from the Turkish Airlines helpdesk helped me to get through. I'm positive I wouldn't have made my flight otherwise. Other than that, this airport can't surprise me anymore. I've never been able to connect to Wifi, shops are okay, but nothing special and staff are fine too. I'd never recommend to anyone to fly through this airport with a shorter connecting time than 3.5hrs.
