I guess this (120 days') practice was introduced to care for the needs of Turkish expats (mainly coming from Germany and other European countries...) for their summer vacations and stays.
-Exactly that is the case. I have friends have been doing it for years and they only visit Turkey once a year. They change the US SIM just before landing. No need to get a new SIM card every year, since the system recognizes the IMEI no on the phone.
But, just like you say. It is Turkey, anything can happen
-Finally, great news from Eksi of THY: TK is working on new uniforms and will be unveiled with the new airport. IIRC, they were designed by an Italian designer, Ettore Bilotta. Pretty, pretty please, please NO overall RED!!!
-TK Business Lounge will have different sections; he says, Business Class passengers, Elite's and Elite Plus's. So, may be 2 lounges one for Elite and one for Elite Plus like SAW domestic. Not sure where you put Star Gold and Business Class paying pax. Any ideas?
