Flight operations across the U.S. are facing significant disruptions due to a shortage of air traffic controllers stemming from an ongoing government shutdown. Major airports, including Los Angeles International Airport (LAX), have issued ground stops as staffing issues intensify. The FAA warns that delays are expected to grow worse, with transportation authorities emphasizing the decreased safety of air travel. Air traffic controllers are reportedly turning to side jobs for financial support, while pilot unions are calling on Congress to end the shutdown. The situation is raising concerns over the impact on upcoming holiday travel and overall passenger experience.
