January 6, 2016: Any time an airline flies over a foreign country, they owe their host country rent for using their airspace. This worldwide service is governed by the International Civil Aviation Organization and includes the airlines right to land, refuel or repair — with additional fees if the plane has to make an unscheduled stop. The foreign air space fee in the US is around $57 a nautical mile. Airlines worldwide might alter their flight route based on the most cost efficient route to their destination.
