As the government shutdown approaches its second month, U.S. airports are experiencing significant flight delays due to staffing shortages, with over 5,000 delays reported last Sunday alone. Transportation Secretary Sean Duffy expressed concerns over air traffic controllers working unpaid and highlighted a shortfall of 2,000 to 3,000 controllers. He noted that ongoing delays and cancellations are necessary to maintain safety amid the staffing crisis, although the situation is frustrating travelers. Duffy reassured that air travel remains safe, stating that the Transportation Department would intervene if conditions became unsafe.
