TSA PreCheck renewals have dropped $15 for online registrations starting October 1. That takes the cost from $85 down to $70 (the cost of initial enrollment for a five-year membership remains $85, however).
Many of those looking to renew will benefit from the price shift without having to change their plan or routine much: More than 95 percent of PreCheck renewals already take place online, the TSA noted in a press release.
