A Quick Guide to TSA PreCheck

Travelers often dread going through TSA security lines, but by signing up for TSA PreCheck, you can save a lot of time and hassle at airport security.

Exactly how much time can you save? We'll put it this way: In April 2024, 99% of TSA PreCheck passengers waited less than 10 minutes at airport security.

Travelers with TSA PreCheck can use dedicated security lines, keep their shoes on and leave their 3-1-1 liquids and laptops in their bags. These benefits are available when flying on dozens of airlines at over 200 airports.

TSA PreCheck is a membership program that offers dedicated airport security lines and streamlined screening at a few hundred airports across the U.S.

Upon approval, members receive a Known Traveler Number that lets the airlines know that you are eligible for TSA PreCheck benefits.

More than 90 airlines participate in TSA PreCheck to provide a smoother airport screening process. Simply add your Known Traveler Number to your flight reservations to receive a "TSA PreCheck" designation on your boarding pass and use the dedicated security lines. On some flights you may not receive TSA PreCheck benefits based on the airline you're flying, which airport you are flying from or TSA procedures.

Children up to 12 years old do not need their own TSA PreCheck membership. As long as they are traveling with an adult who is a member, they can use the TSA Security lanes too. Children ages 13-17 can travel with TSA PreCheck member parents so long as the TSA PreCheck indicator appears on the child's boarding pass as well.

Differences between TSA PreCheck and Global Entry

While TSA PreCheck and Global Entry are both designed to streamline security checkpoints, each is targeted to a specific type of travel.

• TSA PreCheck makes domestic travel simpler, offering dedicated airport security lanes, lower application fees and several locations where you can enroll.

• Global Entry, on the other hand, is best for international travelers. This program includes TSA PreCheck benefits, but also simplifies the U.S. customs process when returning from outside the U.S.

This chart highlights some of the similarities and differences between TSA PreCheck and Global Entry.

The TSA PreCheck program is only open to U.S. citizens, U.S. nationals and lawful permanent residents.

Travelers interested in TSA PreCheck must apply online for pre-approval. Once your interview is booked, you are required to bring an unexpired U.S. government-issued photo identification, plus proof of citizenship. Accepted documents include your passport or a driver's license and birth certificate.

Immigrants can learn more about required documentation on the Homeland Security website.

The benefits sound great, but what is the fee for TSA PreCheck? TSA PreCheck costs $77.95 at Clear enrollment locations, $78 at Idemia enrollment centers and $85 at Telos enrollment centers. The membership lasts for five years. After the initial application fee, PreCheck renewal only costs $70 if completed online. As detailed below, some travel credit cards will help offset this cost.

While you can pay for TSA PreCheck with your credit card or debit card, you can actually get it for free instead of paying cash. Here are four ways to do just that:

Randomly issued. Some passengers may randomly receive TSA PreCheck as a way to introduce them to the benefits of being a member. Consider this a marketing effort by the Department of Homeland Security to encourage people to sign up for TSA PreCheck.

Military benefits. All active members of the U.S. Armed Forces can receive TSA PreCheck benefits by entering their Department of Defense identification number as their Known Traveler Number. This includes those serving as Reserves and National Guard, as well as cadets and midshipmen attending a military academy.

Redeem rewards. Some airline and hotel loyalty programs, such as Marriott Bonvoy and United MileagePlus, allow you to redeem miles and points to pay for TSA PreCheck application fees.

Credit card benefits. Many travel cards reimburse TSA PreCheck application fees every four to five years. Among them:
