U.S. airlines started cancelling hundreds of flights on Friday, hours after the Federal Aviation Administration ordered the cuts amid the more-than-monthlong government shutdown.The cuts were ordered as air traffic controllers have missed their paychecks due to the government shutdown, now the longest in U.S. history. Air traffic control staffing shortages have been disrupting flights at several major U.S. airports, vexing travelers and airline executives alike.Air traffic controller shortages were delaying flights at several major U.S. airports on Friday, including Newark Liberty International Airport in New Jersey, San Francisco International Airport and Hartsfield-Jackson International Airport in Atlanta.The sudden flight cuts this week forced airlines to scramble with schedule adjustments and make sure crews are where they need to be despite the last-minute changes.More than 700 U.S. flights were canceled as of 9 a.m. ET Friday, according to aviation data firm Cirium, about 3% of the total schedule for the day. That scale of disruption is fairly common for routine disruptions like major thunderstorms, but the Department of Transportation warned that cancellations could ramp up.Travelers wait in line at a security checkpoint at O’Hare International Airport in Chicago, Illinois on November 7 2025.

That period also included a Southwest Christmas meltdown after severe weather and mass delays at Delta Air Lines last summer in the wake of a CrowdStrike tech outage.The financial impact of the latest disruptions isn’t immediately clear. The cancellations could help lift airlines’ unit revenue with customers competing for fewer seats, “but we also believe the prolonged shutdown and widespread cancelations will impact booking demand in the near term,” Scott Group, an airline analyst at Wolfe Research, wrote in a note Friday.The cuts come during a generally low-demand period for travel ahead of the Thanksgiving holiday, but it still sent many travelers searching for alternatives. Rental car company Hertz said that reservations over the past two days for one-way rentals spiked more than 20% from the same period last year.[embedded content]Ma …
