S. 5387 — DCA Air Safety Act

This section reduces the Airport Arrival Rate at Ronald Reagan Washington National Airport to no more than 28 aircraft and converts it into binding 30-minute interval caps that evenly distribute arrivals and departures. It permanently eliminates 30 slot exemptions at the airport, at least 26 of which must be beyond-perimeter exemptions, phased in with 6 eliminated each year from 2028 through 2032. It also establishes the Ronald Reagan Washington National Airport Slot Exemption Evaluation Commission to study ongoing safety and operational impacts.
