Southwest Airlines said it was cutting more than 400 flights scheduled for early this week due to ongoing air traffic restrictions issued during the federal government shutdown.

While the shutdown appears poised to end soon, the government has not yet reopened and the Federal Aviation Administration's (FAA) order to reduce air traffic remains in place. Air traffic controllers have worked without pay during the shutdown, with some not showing up for work as it has dragged on.

"We have now reduced our flight schedule through Wednesday across 34 of the more than 117 airports we serve, taking steps to protect the health of our crew network and prevent further unplanned cancellation," Southwest said in a Nov. 10 statement.

The airline said it canceled approximately 140 flights for Monday, Nov. 10, another 155 for Tuesday, Nov. 11 and 145 for Wednesday, Nov. 12, to meet the FAA’s requirements.

The cuts come after Transportation Secretary Sean Duffy said on Nov. 5 that 40 major airports will see a 10% cut in flights. Duffy had previously warned of staffing shortages among air traffic controllers across the United States amid the record-breaking government shutdown. In a Truth Social post on Monday, Nov. 10, President Donald Trump demanded air traffic controllers return to work immediately, threatening to dock the pay of those who didn't.

FAA Administrator Bryan Bedford told CEOs of major airlines that the flight cuts would begin at a 4% reduction on Nov. 7, rise to 5% on Nov. 8 and 6% on Nov. 9 before hitting 10% this week.

Southwest did not specify which 34 airports would be impacted by its cancellations.

What happens if my Southwest flight is canceled?

Travelers with flights booked through Thursday, Nov. 13, may choose to adjust their travel plans at no cost or receive a refund if they choose not to travel, even if their flight is not affected, the company said in a statement, adding that the "vast majority of our customers’ flights will not be disrupted."

International flights are not impacted, the company said.

"We will continue to update customers as this situation evolves," Ashley Persons, a spokesperson for the airline, told USA TODAY. "We continue to urge Congress to immediately resolve its impasse and restore the National Airspace System to its full capacity."
