The Department of Homeland Security (DHS) has announced the suspension of the TSA PreCheck and Global Entry airport security programs as a partial government shutdown continues. With the funding lapse, millions of travelers are expected to lose access to these trusted-traveler programs, which are critical for expediting airport security processes. As major airports face disruptions, U.S. airlines have expressed concerns over the impact on travel. The shutdown reflects ongoing political stalemates regarding DHS funding, with negotiations seemingly at a standstill.
