The Passenger Facility Charge (PFC) Program allows the collection of PFC fees up to $4.50 for every eligible passenger at commercial airports controlled by public agencies. PFCs are capped at $4.50 per flight segment with a maximum of two PFCs charged on a one-way trip or four PFCs on a round trip, for a maximum of $18 total. Airports use these fees to fund FAA-approved projects that enhance safety, security, or capacity; reduce noise; or increase air carrier competition.
