The Federal Aviation Administration is cutting flights at 40 U.S. airports beginning Friday, Nov. 7, as air traffic controllers and TSA agents continue to go unpaid during the government shutdown.

Forty major U.S. airports will experience a 10% reduction in flights due to the federal government shutdown.

Transportation Secretary Sean Duffy warned this week there could be chaos in the skies if the shutdown drags on long enough for controllers to miss their second full paycheck next week.
