The DCA Air Safety Act aims to reduce congestion and improve safety at Ronald Reagan Washington National Airport by limiting the number of aircraft operations at the airport. The bill requires the Federal Aviation Administration to reduce the Airport Arrival Rate to no more than 28 aircraft within 90 days and establish binding 30-minute interval caps to prevent clustering of flights. The legislation also mandates the permanent elimination of 30 slot exemptions over a five-year period from 2028 through 2032, with at least 26 of these being long-distance flight exemptions. The bill establishes a permanent commission composed of representatives from the FAA, Department of Defense, Virginia, Maryland, and Washington D.C. to study DCA conditions and make recommendations to Congress. These changes respond to capacity constraints at the airport, where Congress has authorized 64 additional daily flights since 2000 despite safety concerns highlighted by the January 2025 midair collision involving an American Airlines flight and an Army helicopter.
