I have a 7 hour layover at Ataturk both coming and going. Anybody know if there is free wifi anywhere in the airport? I am going Economy so I won't have access to the TK lounge and I don't think I would pay to get into one of the other lounges just to use wifi. I heard that greenport cafe has free wifi but i'm not sure if that still holds true now. Does the starbucks have free wifi? Thanks!
