The longest government shutdown in U.S. history, now in its 36th day, is severely impacting air travel. The Federal Aviation Administration has mandated a 10% reduction in flights at 40 major airports starting Friday due to staff shortages, with 13,000 air traffic controllers and 50,000 security personnel working without pay. Airlines are adjusting schedules, affecting approximately 1,800 flights and 268,000 seats, though international flights remain unaffected. Major airports including New York, Washington D.C., Chicago, Atlanta, Los Angeles, and Dallas are among those impacted. Passengers are facing delays, cancellations, and uncertainty, with unions and officials emphasizing safety concerns. The shutdown stems from a congressional deadlock over federal spending, leaving government operations paralyzed. Airlines are offering refunds and alternative arrangements, while authorities stress the importance of maintaining safe airspace despite the unprecedented disruption.
