US Transportation Secretary Sean Duffy warned Tuesday that if the federal government shutdown continues another week, it could lead to "mass chaos" and force him to close some national airspace to air traffic, a drastic move that could upend American aviation.
"If you bring us to a week from today, Democrats, you will see mass chaos, you will see mass flight delays. You'll see mass cancellations, and you may see us close certain parts of the airspace, because we just cannot manage it," Duffy said at a press conference Tuesday.
US aviation has already faced tens of thousands of flight delays over the last month. The comments represented the Trump administration's most dire warnings of impending impacts from rising air traffic controller absences.
As the shutdown entered its 35th day, the Federal Aviation Administration delayed a new round of flights on Tuesday. Airlines said this week that 3.2 million passengers have been hit by delays or canceled flights due to a spike in air traffic controller absences.
FAA Administrator Bryan Bedford told Fox Business' "Varney & Co" on Tuesday that at the agency's largest 30 airports, "anywhere from 20 to 40% of our controllers aren't coming to work."
Democrats blame Republicans for not negotiating with them to reopen the government. The shutdown has exacerbated staffing shortages, forcing 13,000 air traffic controllers and 50,000 Transportation Security Administration officers to work without pay.
In 2019, widespread disruptions to air travel pressured lawmakers to end a 35-day government shutdown during President Donald Trump's first term in office.
Risky to travel
Duffy reiterated he would shutter the US aviation system if he thought the shutdown was making it too risky to travel.
On Friday, the FAA said nearly half of the 30 busiest US airports faced shortages of air traffic controllers in the single worst day since the shutdown began.
In New York on Friday, 80% of air traffic controllers were absent, the agency said.
