The disruptions, which have left some travelers waiting hours in line, have reignited interest in expedited screening programs like TSA PreCheck and CLEAR, with Google search interest spiking in recent days.

Air travelers have a new way to shorten their wait times at the security screening line at the airport. The Transportation Security Agency (TSA) is allowing frequent fliers to sign up for TSA PreCheck Touchless ID.

This is all due to the partial government shutdown that has taken place because of the lapse in funding for the Department of Homeland Security (DHS), which oversees the Transportation Security Administration (TSA).

Touchless ID is especially relevant now as the partial government shutdown continues to create long security lines at airports across the country.

If you’re thinking of getting TSA pre-check to deal with massive spring break crowds at airports, it may be too late.
