The Department of Homeland Security on Sunday suspended the TSA PreCheck and Global Entry security programs that speed through airport security checkpoints, citing a partial government shutdown.

The move comes as the U.S. Northeast braces for a massive winter storm that could disrupt airline flights for days.

The pause took effect at 6 a.m. ET on Sunday, DHS said.

“TSA and CBP are prioritizing the general traveling population at our airports and ports of entry and suspending courtesy and special privilege escorts,” DHS Secretary Kristi Noem said in a statement.

TSA PreCheck has more than 20 million active members, according to an agency count in 2024.
