The Federal Aviation Administration will pause hundreds of passenger flights from Ronald Reagan Washington National Airport to accommodate President Donald Trump’s extravagant military parade on June 14.

The flights will be disrupted to accommodate the planned flyovers over the National Mall and the fireworks display across the Potomac River. According to an FAA briefing document, viewed by the Washington Post, about 100 flights will be delayed at their departure airports for an average of three hours. Few, if any, flights will be allowed in or out of the airport from 6 p.m. to 9:30 p.m.
