Air passengers may encounter more disappointment as busy U.S. airports must meet the Federal Aviation Administration's loftier goal of cutting flights on Tuesday after already canceling thousands of flights to reduce demands on the nation's aviation system during government shutdown.
Last week, the FAA ordered domestic airlines to cancel 4% of their flights in 40 major US airportsstating that the absence and signs of stress among traffic controllers require action in the name of public safety. After more than 7,900 flights have already been canceled since Friday, the flight reduction target is set to rise to 6% on Tuesday and again to 10% on Friday.
More than 1,100 flights were canceled Tuesday, according to FlightAware, a website that tracks air travel disruptions. It is unclear exactly how many additional flights will have to be canceled that day.
The average flight cancellation rate over the past few days has already exceeded FAA requirements, according to aviation analytics company Cirium. The FAA also expanded flight restrictions Monday, banning business jets and many private flights from using a dozen airports already subject to commercial flight restrictions.
However, the dispatcher shortage continued to cause flight delays, including about five hours for incoming flights Monday night at Chicago O'Hare International Airport, where winter weather added to the personnel outages earlier in the day. The FAA warned that personnel at more than a dozen towers and control centers could delay planes flying to Phoenix, San Diego, the New York area and Houston, among other cities.
Freezing weather in parts of the country on Tuesday could lead to further flight delays and cancellations.

The Senate passed legislation on Monday to reopen the governmentbut the bill still needs to be approved by the House of Representatives and could be days away from final passage. Transport Minister Sean Duffy made it clear Last week's flight cuts will continue until the FAA sees air traffic control staffing levels stabilizing.
Many planes are also not where they should be, which could slow airlines' return to normal operations even after the FAA lifts the order, said Mike Taylor, who heads airport and airline research at JD Power.
Todd Walker said he missed his mother's 80th birthday when his flight was canceled over the weekend.
“All of this has real negative consequences for millions of Americans, and it is 100% unnecessary and avoidable,” he said.
The FAA came under fire after its initial order only covered a very small portion of private jets. But some want more to be done.
The Patriotic Millionaires, a group of wealthy Americans who advocate for more progressive taxes, are calling for all private jets to be grounded during the coronavirus shutdown.
“Rich people ride their bikes while average Americans can't get to grandma's bedside in time,” said Erica Payne, the company's founder and president.
She added that none of her members who still fly private have reported cancellations or delays since the FAA order went into effect.
Tuesday marks the second missed payday for supervisors. Some began quitting their jobs, citing stress and the need to find a second job.
It's unclear how quickly controllers will be able to get paid after the shutdown ends — it took more than two months to receive full compensation after a 35-day shutdown that ended in 2019, said Nick Daniels, president of the National Air Traffic Controllers Association.
President Donald Trump took to social media Monday to put pressure on supervisors to “get back to work NOW!!!” He called for a $10,000 bonus for those who stayed on the job and offered additional pay for those who didn't.
Daniels said the shutdown made the difficult job of dispatchers even more stressful, leading to fatigue and increased risks. He said the number of those retiring or leaving the workforce was “growing” every day.
