I had a request to explain how landing fees are computed, so here's a brief explanation:
The airport operator has a budget that it must meet, a budget that allows for makeup of reduced revenues, or credits to tenants if revenues exceed expenses.
The airport first computes its expected expenses for the course of the fiscal year. These include operational/maintenance expenses, capital improvement programs, debt service on bonds, personnel, etc, etc.
Then the airport computes its expected non-aeronautical revenues. These include revenues from the concession operations, parking garages, taxis/limos/shuttles, airline/rental car/other tenant gate and office space rental fees, etc.
The non-aeronautical revenues are then totalled up, and subtracted from the expected revenues. The dollar figure that is left over is made up via the landing fee, which is the base number that the landing fee is made up from.
As I mentioned previously, if the airport has a revenue surplus, that surplus is then credited back to the tenants. An underage would be billed to the tenants.
It's a bit more complicated than that.....but that's a Reader's Digest version.
