The U.S. government shutdown has led to widespread travel disruptions, with airlines canceling over 1,200 flights in a single day and continuing cancellations affecting major airports nationwide. Experts warn that if the shutdown extends into the weekend, the situation could worsen dramatically, impacting Thanksgiving travel. The FAA has mandated flight reductions across 40 airports, resulting in increased delays and cancellations, especially in states like California. Air traffic controllers and TSA screeners are also struggling due to understaffing, further complicating travel plans. While a resolution to the shutdown may be on the horizon, airlines and officials caution that recovery for air travel could take an extended period, with disruptions likely lingering even after services resume.
