JACKSONVILLE, Fla. – Travelers, brace yourselves — flight schedules are about to get tighter.
Starting Friday, the Federal Aviation Administration will cut air traffic nationwide because of the ongoing government shutdown.
U.S. airports in more than two dozen states are among those facing 10% reductions in air traffic.
A list distributed to airlines and obtained by The Associated Press includes airports in New York, Chicago and Los Angeles among the 40 that will see flights slashed.
The cuts could include up to 1,800 flights, according to estimates.

While Jacksonville International Airport is not on the list, a trickledown is expected because of reductions at important hubs like Atlanta, Houston and Miami.
“The entire system will be impacted” by the cuts, said Michael Stewart, Jacksonville Aviation Authority’s vice president of external affairs. “It is important that travelers check with their airline for any impact these changes may have on their scheduled flight.”
The FAA is imposing the reductions to take pressure off air traffic controllers, who are federal employees and have gone without pay during the shutdown.
In addition to reduced flight traffic, the shutdown has led to more flight delays, with experts advising travelers to check flight statuses before heading to the airport, among other tips.

Travelers News4JAX spoke with at JAX on Thursday said that even though the cuts haven’t started yet, the airports they were flying in from were already packed.
Frequent traveler Doug Mostrom, who was flying to New Orleans, said he understands why the cuts are necessary.
“It’s unfortunate it’s happening because of the political climate, but it’s necessary to maintain safety,” said Mostrom. “You can’t put airplanes in the air without air traffic controllers.”
Mostrom said he left a day early to avoid getting caught in potential delays once the reductions take effect.
Other travelers who arrived to Jacksonville from Iowa said their flights had not been affected yet, but they’re keeping an eye on the situation.
“We were a little worried for the trip, but when we got to the airport, everything went smoother than expected,” said Louie Wickett. “So, but I know they plan to do something Friday, so we’re a little worried about the way home.”
Airlines say they’re working to adjust schedules and limit the impact on travelers. It’s not clear when the reduced flights could end.
Here’s a closer look at what to know about the reductions.
Which airports are affected?
The list includes 40 airports with Atlanta, Denver, Dallas, Miami, Newark and San Francisco among them. A full list of airports facing reductions is here.
Why is this necessary?
Air traffic controllers have gone without paychecks during the shutdown of the federal government. That’s led to controllers calling in sick and contributed to staffing shortages that have been affecting air travel for weeks.
Most controllers work mandatory overtime six days a week during the shutdown without pay, the National Air Traffic Controllers Association has said.
That leaves little time for a side job unless controllers call in sick to the FAA.
When will the reductions begin and end?
They’re set to start Friday, with passengers expected to be notified on Thursday. Airlines have said people could see weekend travel plans disrupted with little notice.
It’s unclear when the reduced flights could end. Airlines, unions and the travel industry have urged Congress to end the shutdown, which on Wednesday became the longest on record.
What will the effect of the reduction be?
The cuts could include up to 1,800 flights and about 268,000 seats combined, according to one estimate.
United Airlines and Delta Air Lines both said they would offer refunds to travelers who opt not to fly, even if they have tickets that aren’t normally refundable.
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.
Has this happened before?
FAA Administrator Bryan Bedford said this week that he’s never seen these kinds of measures taken before in his nearly four-decade experience in the aviation field.
“We’re in new territory in terms of government shutdowns,” he said.
Staffing problems led to delays throughout October, but they were mostly isolated and temporary. Last weekend, though, saw a change.
From Friday to Sunday evening, at least 39 air traffic control facilities reported potential staffing limits, according to an Associated Press analysis of operations plans shared through the Air Traffic Control System Command Center system. The figure, which is likely an undercount, is well above the average for weekends before the shutdown.
During weekends from Jan. 1 to Sept. 30, the average number of airport towers, regional control centers and facilities monitoring traffic at higher altitudes that announced potential staffing issues was 8.3, according to the AP analysis.
