As the partial government shutdown continues, small U.S. airports may be forced to close due to increasing absences among TSA staff. Officials warn that funding disputes could lead to significant operational challenges, including longer security lines and potential airport closures. The situation is exacerbated by unpaid TSA officers calling out in large numbers, leading to significant delays and cancellations at major airports like Philadelphia and Atlanta. Airline CEOs are urging Congress to end the shutdown and ensure TSA workers are paid, emphasizing the negative impact on travel and airport operations. With reports of financial hardship among TSA workers and some having to quit their jobs, the escalating crisis raises concerns about the safety and efficiency of airport security.
