Wife and I are trying to purchase tickets to watch Galatasaray in Turk Telecom Arena on 01 September. We are leaving for Istanbul soon and have not been able to find tickets online. I've tried biletix.com but do not see them for sale yet. What is the best way to purchase tickets? I'm afraid they will be sold out if we try to purchase them on match day. I emailed our hostel and they told me to purchase the tickets when I arrive at the Biletix but not online...? Not sure what they meant. Any advice?
