Severe staffing shortages at TSA checkpoints, caused by a partial government shutdown freezing paychecks, have led to extensive delays and long security lines at major U.S. airports, notably at Houston’s George Bush Intercontinental Airport where wait times have stretched for hours. The shutdown has forced over 400 TSA officers to quit and many others to call out, prompting deployment of ICE agents and additional TSA personnel to assist, while airlines and travelers face growing frustration and operational disruptions. As lawmakers remain deadlocked over DHS funding and immigration enforcement reforms, airports nationwide continue to experience significant delays, with experts advising passengers to arrive much earlier than usual for flights.
