I don't think there are many airports in that part of the world that will permint the disembarkation of uniformed troops. Although if you want to wander around an middle eastern airport in your combats you are welcome to try!
I am also pretty sure that 216 don't get to pick and choose their routes / refuel stops "for their convinience." Factors such as fire cover, PCNs and Dip Clears are all taken into account.
Just a guess mind.
