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.
