The shutdown has taken a toll on the staffing levels of air traffic controllers, with roughly 13,000 working without pay.

The secretary of transportation predicted “mass chaos” next week if controllers have to continue to go without pay through a shutdown.

Transportation Secretary Sean Duffy warned that the ongoing government shutdown may result in the closure of portions of U.S. airspace, which he predicts will lead to "mass chaos."

The Department of Transportation might be forced to shut down the airspace in certain parts of the country if the government shutdown continues into next week.

Transportation Secretary Sean Duffy said the agency may need to close "certain parts of the airspace" if the shutdown continues.

Transportation Secretary Sean Duffy warned that flights across the country could be delayed or even canceled due to the ongoing government shutdown.
