How's your TSA PreCheck status? Thousands of PreCheck memberships are set to expire this year. The bottom line for travelers is that it pays to remember your PreCheck anniversary.

This year is a big year for expired memberships because TSA PreCheck memberships last for five years. The TSA first began selling memberships at airports in December of 2013. The TSA managed to register more than 420,000 members during the first six months of the program's launch. That number was nearly doubled by the end of PreCheck's first year. That means that close to 800,000 travelers need to get serious about renewing their memberships in the months to come.

The good news is that you won't be forced to pay a higher price for TSA membership than what you paid when you enrolled for the first time. The price of membership has held steady at $85 for five years. TSA officials expect that most members will make the choice to renew their memberships. You can renew your membership up to six months in advance at an enrollment center or using the PreCheck website.

The TSA is notifying members of soon-to-be-expired memberships by email and telephone. You can also check the status of your membership using the PreCheck website. Members of the Global Entry program should also be aware that expiration dates are looming. That program also offers membership on a five-year basis.
