The Federal Aviation Administration says it plans to reduce air traffic by 10% across 40 “high-volume” markets beginning Friday morning to maintain safety during the ongoing government shutdown.

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.

The FAA released the list of affected airports Thursday, with a focus on areas that have been struggling most with air-traffic-control staffing shortages. The list includes some of the nation’s biggest, busiest airports, including those in Atlanta, Chicago, Dallas and New York City.
