Why do people keep asking questions when they are flying ? Dude , just stay there at airport. What are you going to do in 12 hrs? Of course there will be hassles here and there unless you are special passports or the prince of arab.Two hours min for the hassles . You will have max 10 hours . 6 hours to sleep . So what will u do with 4 hours ? Too many questions about how is the flight how is the route how is this how is that .
