How Are Overflight Fees Calculated And Paid?

Sun Jul 14, 2013 5:13 am


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?

It varies from nation to nation but most common its distance based from entry point to exit point of applicable FIR.

Some nations is actual distance flown, while others its based on filed intended route. Also fees for some are fixed per distance measure unit, while others also have a weight factor involved.

Individual country specifics can be found in their AIP publications, while trade groups like IATA also publish data regularly.

Not sure if you have seen this, but here is the FAAs overflight feed website:

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.
