Airlines and their customers (passengers and shippers) pay many special taxes and fees to a variety of authorities, both at home and abroad. Among the stated purposes of these taxes and fees are homeland (national) security, environmental protection, agriculture inspection, infrastructure enhancement, airport and airway operations and maintenance, and agency financing. U.S. and foreign taxes have grown in number, amount, and scope since the advent of air transport. The amount a passenger pays in taxes and fees on a ticket varies according to his itinerary, including the number of times he or she boards a new flight and at what airports. In addition to the special taxes and fees captured in the table below, the Federal Aviation Administration also charges overflight fees to operators of aircraft that fly in U.S.-controlled airspace, but neither take off nor land in the United States.
