Looking on Flightradar24 I am interested to see the rather odd routing that most flights use from Western Europe to SE Asia and Australia. It is extremely busy and not that direct, being too far north.
They all seem to use a very narrow airway from the Black Sea to the Persian Gulf, passing Mosul, Baghdad, Basra and Kuwait. There appears to be a ban on overflights of both Saudi Arabia and Egypt, as the only flights there are local, or other Gulf carriers. Flights to Africa pass over both countries, but not western carriers to Asia and Australia. Why?
Which countries currently ban overflights and why? Is it due to political, threats, military activity, or just a cheaper routing.
Is it more economic to fly over Northern Europe, through the old Eastern Bloc, than down through France, Italy and over the Adriatic and Eastern Med?
