Many TSA agents, who are not getting paid due to the partial government shutdown, have stopped working. That means long waits at airport security.

TSA said Sunday that its PreCheck program would remain operational after previously saying it would be suspended during the partial government shutdown.

DHS reversed course on suspending TSA Precheck, which is used by more than 20 million people, after an outcry from industry groups and passengers.

Being part of just one airport program that speeds you through security may not be enough anymore, especially when events like government shutdowns, major storms, and system outages can create long lines and travel disruptions.

TSA Pre-Check will remain operational for now, a reversal from previous directives from the Department of Homeland Security. The expedited screenings were originally on hold amid the ongoing partial government shutdown.

The Transportation Security Administration programs are designed to help speed registered travelers through security lines. Suspending them due to the partial government shutdown could cause delays.

The department said that it would suspend the priority airport security programs on Sunday, about a week after its funding lapsed.

The Department of Homeland Security reversed course, saying TSA PreCheck remains operational despite the government shutdown.

The Department of Homeland Security announced emergency measures that could affect air travelers nationwide and at Phoenix Sky Harbor Airport.
