In the United States, the federal passenger facility charge (PFCs) program allows the collection of PFC fees up to $4.50 for every enplaned passenger at commercial airports controlled by public agencies.
Airports use these fees to fund FAA-approved projects that enhance safety, security, or capacity; reduce noise; or increase air carrier competition.
Federal law limits use of PFC funds strictly to the above categories.
[1] Depending on the location, the airport improvement fee is included in the cost of traveller's airline ticket, in which case the airline will forward the fee to proper agency.
[citation needed] In some instances, the fee continues to be charged long after construction has been completed (e.g. Ottawa Macdonald–Cartier International Airport).
