The FAA issued two NOTAMs mandating temporary flight pauses at Ronald Reagan Washington National Airport on 3 and 4 July 2026, totaling nearly 15 hours to accommodate Independence Day rehearsals. These regulatory closures restrict all nonscheduled general aviation and pause operations at select times for military flyovers, aerial displays, and evening fireworks tied to the 250th anniversary observance. Operators must file alternate routes or delay flights, while commercial scheduled carriers may face minor schedule adjustments if relying on DCA for connections during the pause windows. The NOTAMs specify no flights after noon on 4 July to ensure airspace safety for ceremonial events, with precise timing detailed only in the full NOTAM text.
