I was hoping someone could explain to me how airlines and aviation authorities around the world calculate, invoice, and pay overflight fees. Also, are the fees based on length of time spent in a specific country's airspace? Or is it a flat fee? Is the fee invoiced based on a planned route, actual? How and when is it invoiced and how and when is it charged? e.g. once a month, for every flight?

Now I cannot give you specifics on the answer to your question, but as an interesting piece of information the two airlines I have worked for have both restricted their MTOM of their aircraft to reduce overflight fees. Where and when this applies I could not say but I assume in Europe it is relevant in any EASA state (I am prepared to be comprehensibly corrected on this). The general point is that it is cheaper for the airline (operating predominantly in Europe) to reduce the MTOM of an aircraft to reduce the en-route ATC charges that they pay. The actual weight of the aircraft does not seem to be taken into consideration. I imagine to do so would be a ridiculously complicated task.
