What type of fee does an airport charge for the amount of fuel pumped at its facilities?

The correct answer is the fuel flowage fee, which is specifically designed to charge for the amount of fuel that is pumped at airport facilities. This fee is typically assessed on fuel suppliers and is intended to cover the costs associated with the infrastructure and services provided by the airport for refueling operations. It helps airports manage the environmental impact, ensure compliance with regulations, and maintain the safety and efficiency of fuel-handling operations.

The reason this fee is distinct from other types of fees is that it directly relates to fuel distribution rather than general operational or facility use. For example, a landing fee is charged for aircraft landing on the runway, while a terminal rental fee pertains to leasing space at terminal facilities. A concession fee usually relates to sales rights or services provided within the airport, such as retail or food services. The fuel flowage fee specifically addresses the activities and infrastructure connected to the transfer and storage of aviation fuel, making it the most appropriate choice in this context.
