New Federal Aviation Administration regulations mandating the shutdown of runway operations at Washington's Reagan National Airport during President Donald Trump's helicopter movements are causing significant disruptions for airlines and passengers.

What Happened: The restrictions, implemented after the Jan. 29 collision between an Army helicopter and an American Airlines jet that killed 67 people, have forced dozens of flights to circle in holding patterns or divert to alternate airports including Dulles International, Baltimore-Washington International, Marshall and Richmond International, reported Washington Post, citing sources.
