Air travel is currently being disrupted nationwide as the US government shutdown continues to worsen longstanding air traffic control shortages. The Federal Aviation Administration (FAA) reported staffing shortfalls at a dozen facilities across the country on Monday. Both Newark Liberty International Airport (EWR) and Denver International Airport (DEN) saw average delays exceeding 30 minutes, and Burbank Airport (BUR) even had no controllers in the tower for five hours and saw traffic directed remotely.
