Is this still about Istanbul? On another thread, I just accused Platinum Guy of intentionally taking inflammatory stances, but I will have to concur on this point, there is no problem with Istanbul airport.

It's a safe place. I'd have no problem sitting down on a bench and falling asleep there. I would never, ever, ever even DREAM of doing that in half the neighborhoods in Brooklyn.
