As a government shutdown persists, air traffic controllers are facing increased stress and staffing shortages, leading to notable flight delays at several major airports. Transportation Secretary Sean Duffy has highlighted that the shutdown places additional strain on an already understaffed air traffic control system. Reports indicate a slight uptick in sick calls from controllers, causing operational challenges. Key airports such as Newark, Denver, and Boston Logan are experiencing delays as a result. Meanwhile, essential air service funding is at risk of expiring soon, raising concerns over the impacts on rural air travel. Air travelers are being warned to prepare for potential disruptions as the shutdown unfolds, with ongoing efforts to address the staffing issues affecting the FAA and TSA.
