These 5 California Airports Will See Flight Reductions

SAN FRANCISCO, CA — Five California airports will see fewer flights as the government shutdown drags into a second month.

The cuts will start to take effect on Friday. Travelers should check with their airlines to see if their flight has been cut. The Federal Aviation Administration said the move is intended to keep the airspace safe during the shutdown.

San Francisco International Airport (SFO) will be one of five California airports subjected to flight restrictions.

SFO has experienced mounting flight delays over the last month, in part due to staffing shortages at the control tower caused by the federal government shutdown.

SFO is ranked the 13th-busiest airport in the country, according to an analysis of 2024 passenger traffic in North America by Airports Council International, a global trade association.

The other four airports expected to have flights cut are:

• Los Angeles International Airport (Ranked 5th-busiest airport in the United States)
• Oakland San Francisco Bay International Airport (Ranked 48th- busiest airport in the United States)
• Ontario International Airport (Not ranked in the top 50 of busiest airports in the United States)
• San Diego International Airport. (Ranked 28th-busiest airport in the United States)

Official confirmation on the targeted airports is expected later Thursday.

Experts predict hundreds, if not thousands, of flights could be canceled. The cuts could represent as many as 1,800 flights and upwards of 268,000 seats combined, according to an estimate by aviation analytics firm Cirium.

“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,” Bedford said Wednesday. “We’re in new territory in terms of government shutdowns.”

Air traffic controllers have been working unpaid since the shutdown began on Oct. 1. Most work mandatory overtime six days a week, leaving little time for side jobs to help cover bills and other expenses unless they call out.

Mounting staffing pressures are forcing the agency to act, Bedford said Wednesday at a news conference.

“We can’t ignore it,” he said, adding that even if the shutdown ends before Friday, the FAA wouldn't automatically resume normal operations until staffing improves and stabilizes.

Major airlines, aviation unions and the broader travel industry have been urging Congress to end the shutdown, which on Wednesday became the longest on record.

The shutdown is putting unnecessary strain on the system and “forcing difficult operational decisions that disrupt travel and damage confidence in the U.S. air travel experience,” said U.S. Travel Association President and CEO Geoff Freeman in a statement.

Duffy warned earlier this week that there could be chaos in the skies if the shutdown drags on long enough for air traffic controllers to miss their second full paycheck next week.

Some controllers can get by missing one paycheck, but not two or more. And he has said some controllers are even struggling to pay for transportation to work.

Staffing can run short in both regional control centers that manage multiple airports and individual airport towers, but this doesn't always lead to flight disruptions. Throughout October, flight delays caused by staffing problems had been largely isolated and temporary.

But the past weekend brought some of the worst staffing issues since the shutdown began.

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. But during the five weekend periods since the shutdown began, the average more than tripled to 26.2 facilities.
