When you click on that hyperlink or button, you may be directed to the credit card issuer’s website where you can review the terms and conditions for your selected offer. Each advertiser is responsible for the accuracy and availability of its ad offer details, but we attempt to verify those offer details.

    Get Free TSA PreCheck With These Cards!

    There are several cards that will cover the price of enrollment in Global Entry or TSA PreCheck, including:

    After you use these cards to pay for Global Entry or TSA PreCheck, you’ll get a statement credit for the expense!

    I recommend signing-up for Global Entry instead of TSA PreCheck.

    That’s because when you have Global Entry, you’ll also be approved for TSA PreCheck on most flights.  And Global Entry also helps you avoid the long lines at US Customs & Immigration when you return to the US from overseas.  So it’s like getting a 2-for-1 deal!

    Here’s how to fill out the Global Entry application.

    Bottom Line

    If you have Global Entry or TSA PreCheck, be sure to add your Known Traveler Number (KTN) to your airline accounts so you can get expedited screening next time you fly!

    It only takes a minute.  And can save you lots of time and frustration at the airport.  Especially if you fly with any of the airlines that participate in TSA PreCheck.
