In the United States, the federal Passenger Facility Charge (PFC) 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.
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. However, in some locations the fee must be paid at the point of embarkation. This often creates difficulties for departing passengers who are unfamiliar with this type of procedure, or for departing international passengers who have already exchanged all their local currency. The amount varies usually between US$10 and US$30. In some instances, the fee continues to be charged long after construction has been completed (i.e. Ottawa Macdonald-Cartier International Airport). A legitimate reason for this is that the airport must finance the cost of the improvement and then pays off these costs over an extended period of time.
Airports currently collecting an explicit airport improvement fee include:
