Airlines are reducing flights at 40 airports under FAA orders. Here’s which airports are affected and how travelers can prepare for delays and cancellations.

On Wednesday, Nov. 5, U.S. Department of Transportation Secretary Sean Duffy announced plans for the department to reduce flight traffic by 10% at 40 airports across the country. Here's how it could impact your travel plans.

American Airlines said that the 4% reduction will mean 220 canceled flights per day. The vast majority of impacted American Airlines flights are regional, and there’ll be no impact to international flights including Mexico, Canada and the Caribbean, CEO David Seymour said in a letter to employees. Further hub-to-hub routes impact will be minimized.

Transportation Secretary Sean Duffy announced that 40 major airports will see a 10% cut in flights, starting the morning of Nov. 7.

Travelers with upcoming travel plans can expect to see fewer flights to many major U.S. cities. The Federal Aviation Administration reduced traffic across 40 airports starting Friday to ease the load on the nation’s air traffic controllers.

“Even if the government reopens quickly, the impacts of the shutdown are still likely to be felt for days and weeks to come as airlines and airports get back to business, so don’t expect air travel to revert to normal anytime soon,” he noted.

Airlines are reducing flights starting Friday under a new FAA directive. Here’s how United, Southwest and American are handling it.

The Federal Aviation Administration is expected to announce Thursday which airports will be affected by nationwide flight reductions, prompted by the ongoing government shutdown.
