Which airports are being affected by FAA cuts? How can I navigate the chaos?

The Federal Aviation Administration's decision to reduce commercial air traffic at 40 airports by up to 10% starting Friday is expected to have wide-ranging impacts in California and across the country.

The cuts have been prompted by the government shutdown, which has left air traffic controllers working without pay. FAA officials say the goal is to maintain safe travel. Since the shutdown began on October 1, nearly 13,000 air traffic controllers have been working without pay or calling in sick.

With fatigue among controllers growing, Transport Secretary Sean Duffy said he did not want to wait until staffing pressures compromised safety.

What will change?

Up to 1,800 daily flights could be canceled throughout the country.

The cuts could affect about 1,800 flights and 268,000 passengers a day in the United States, according to aviation analysis firm Cirium. At Los Angeles International Airport alone, some 72 daily flights could be reduced, which would affect 12,371 daily passengers, Cirium estimated. An additional 105 flights could be canceled at the other four California airports slated for reductions.

When will the reductions begin to be noticed?

A shortage of air traffic controllers has caused delays for weeks, including at LAX and Burbank airport. But officials said the flight reductions will begin Friday and continue until they reach a 10% cut.

Authorities urged passengers to check with airlines about the status of their flights, but warned that flights could be canceled without notice.

  • The FAA has a website that tracks national airspace issues.
  • Experts recommend monitoring your airlines' websites and receiving alerts on your phone.
  • Here are more tips.

Officials said the decision to cut flights was motivated by data about which areas were facing increased staffing pressures that could compromise safety.

“This is not based on which airline … has the most flights from which location,” Duffy said. “Is it about where the pressure is and how to relieve it?”

What about international flights?

International flights are expected to be exempt from the cuts. But passengers taking connecting flights before heading abroad could face problems as the cuts affect several of the country's busiest hubs, including Atlanta, Denver, Dallas, Orlando and Miami.
