On Sunday, more than 2,700 flights were canceled primarily due to the ongoing government shutdown and the Federal Aviation Administration's (FAA) directive to reduce air traffic.
U.S. Transportation Secretary Sean Duffy warned that if the federal government shutdown continued through the busy Thanksgiving travel season, air traffic could “slow to a trickle.” The reduction in flights affected 40 of the nation’s busiest airports and marked the third consecutive day of severe disruptions.

The FAA ordered cuts in flights after some air traffic controllers, unpaid for nearly a month, began not showing up for work. On Sunday alone, close to 10,000 flight delays were reported, according to FlightAware, a website that monitors air travel disruptions.
