Airport and Airway Development Act (1970)
Congress created the Airport and Airway Trust Fund, funded by taxes on airline tickets, aviation fuel, and cargo. The law made that money available for airport and air traffic control improvements.
Airports gained a dedicated federal funding stream for infrastructure, independent of the general budget.
The trust fund remains the main source of money for FAA airport grants and air traffic modernization.
This is the funding pool that the $21.4 million Chicago taxiway grant draws from.
