Airlines largely kept schedules Friday even as more than 1,000 flights were cut amid the government shutdown, with the FAA ordering reductions at 40 of the nation’s busiest airports. Air traffic controllers, unpaid for nearly a month, are calling out, prompting cancellations and long security lines from Atlanta to Denver. Reagan National saw the biggest hit, while carriers trimmed mostly regional routes and rebooked many passengers. International flights were not expected to be affected. The FAA plans to ramp cuts from 4% to 10% next week; officials warned cancellations could reach 15%–20% if the shutdown persists.
