MORE than 800 flights across the US have already been canceled as millions of travelers brace for even more chaos.
Airlines have frantically cut routes after federal officials ordered 40 major airports to slash capacity.
It comes as US vice president JD Vance warned the country faces an “aviation emergency.”
“The shutdown has now passed from farce into tragedy, and the consequences of this national emergency fall on every senator and congressman who refuses to open the government,” he railed.
The total number of canceled flights now stands at more than 800, according to FlightAware.
Dozens of flights originating out of Chicago airport, Hartsfield-Jackson in Atlanta, Denver and Fort-Worth have been axed.
Forty flights departing Chicago have been axed, and 38 from Atlanta.
Southwest has canceled more than 120 flights, which is 3% of its total, while United has cut 2%.
At least 20 flights heading out of Los Angeles, Newark, and San Francisco have also been culled.
More than 1,200 flights are experiencing some form of delays.
Five percent of flights leaving JFK airport and Chicago are delayed.
Passengers arriving into Newark were met with three hour delays on Thursday night.
One airport worker told The New York Post the situation on Friday will be a nightmare.
“Tomorrow, the FAA will just shut down. Get out while you can,” they warned.
Federal officials have warned how the current shutdown is unprecedented.
“I’m not aware in my 35-year history in the aviation market where we’ve had a situation where we’re taking these kinds of measures,” Bryan Bedford, the FAA administrator, said.
“Then again, we’re in new territory in terms of government shutdowns.
The current shutdown is the longest in US political history.
It surpassed the 2018-19 federal government closure, which Donald Trump also presided over, in terms of length.
FAA officials ordered a slew of airports to reduce capacity.
This is part of a bid to keep the skies safe while there is a shortage of air traffic control workers.

Air traffic controllers have gone without a full months pay because of the shutdown.
Airports on the FAA’s list include major hubs such as Los Angeles International, Orlando, New York’s JFK airport, and Miami.
San Francisco and Oakland airports are also on the list of hubs ordered to cut capacity by 10%.
Earlier this week, Transportation Secretary Sean Duffy told Americans that air travel would need to be reduced to prevent any casualties.
“We will restrict the airspace when we feel it’s not safe, if we don’t have enough controllers to effectively and safely manage our skies,” he said.
Airlines have responded to the FAA’s order.
Scott Kirby, the CEO of United, revealed schedules will be updated on a rolling basis.
The airline’s international flights are not impacted by the restrictions.
He revealed travelers can apply for a refund even if their flight isn’t delayed or canceled.
He expects the carrier to still offer around 4,000 flights a day despite the restrictions.
Southwest Airlines has said it will rebook impacted customers.
And, American will liaise with travelers about new flights if they are impacted.
Meanwhile, on Capitol Hill, lawmakers are working to end the shutdown.
Senate Democrats have voted 14 times not to reopen the government.
But, Senate Republicans want to bring forward new funding bills that will see the government reopen.
One bill top GOP lawmaker John Thune is proposing would see programs funded until December or January.
