U.S. airports have been lobbying Congress for more money, at the expense of the flier.

USA Today reports that airlines have asked Congress to raise the "passenger facility charge" – a fee fliers pay, which is included in the overall price of airline tickets.

Currently, the charge is $4.50 for each flight on the booked trip but airports would like to see the fee increased to $7.50 per each leg of the trip. The money goes to fund airport improvements including runway rebuilding and terminal redesigns.

In order to see addition funding for airport projects, airports have to apply for approval to the FAA for every project that needs additional cash flow. These projects are usually paid for from airline ticket fees and federal grants.

Funds from the passenger facility charge are supposed to be used only for construction projects that enhance safety, security or capacity, reduce noise or increase air carrier competition, according to the FAA.
