If you’ve ever stood barefoot in a long airport security line, juggling your laptop and toiletries while trying not to hold up the people behind you, you know how stressful flying can be. That’s exactly why TSA PreCheck was created.

Run by the Transportation Security Administration, TSA PreCheck is a trusted traveler program designed to make airport security faster and less intrusive for low-risk passengers. For many travelers, it transforms the entire airport experience from chaotic to efficient.

In this guide, you’ll learn what TSA PreCheck is, how it works, how much it costs, who qualifies, and whether it’s truly worth it.

What Is TSA PreCheck?

TSA PreCheck is an expedited airport security program available at more than 200 airports across the United States. Once approved, members can use dedicated security lanes that move significantly faster than standard lines.

The biggest difference? You don’t have to unpack half your carry-on bag.

With TSA PreCheck, you typically:

• Keep your shoes on
• Leave laptops inside your bag
• Keep light jackets and belts on
• Leave compliant liquids in your carry-on

While standard screening requires removing several items, TSA PreCheck simplifies the process. That convenience alone makes it appealing to frequent flyers.

How Does TSA PreCheck Work?

The process begins with an application and background check. Once approved, you’ll receive a Known Traveler Number (KTN). This number is essential—it links your identity to your trusted traveler status.

When booking flights, you enter your KTN into your airline reservation. If everything matches correctly, your boarding pass will display a TSA PreCheck indicator. That mark gives you access to the expedited lane at participating airports.

It’s important to understand that TSA PreCheck applies to security screening before departure, not to customs when returning from international travel.

How Much Does TSA PreCheck Cost?

As of 2026, TSA PreCheck costs approximately $78 to $85 for a five-year membership, depending on the enrollment provider you choose.

When broken down, that’s about $16 per year—less than many airport meals.

Even better, many travel credit cards offer reimbursement for the TSA PreCheck application fee. If you already carry a premium travel card, your membership could effectively cost you nothing.

How to Apply for TSA PreCheck

Applying is straightforward and typically takes less than 15 minutes of your time.

Step 1: Submit an Online Application

Complete the application form with basic personal information.

Step 2: Schedule an Enrollment Appointment

Choose a nearby enrollment center for identity verification and fingerprinting.

Step 3: Attend Your Appointment

Bring valid identification, such as a passport or driver’s license. The appointment itself usually takes about 10 minutes.

Step 4: Wait for Approval

Many applicants receive approval within 3–5 days, though processing can take a few weeks in some cases.

Once approved, you’ll receive your Known Traveler Number and can start using TSA PreCheck immediately when flying with participating airlines.

TSA PreCheck vs. Global Entry

Travelers often compare TSA PreCheck to Global Entry, another trusted traveler program.

Here’s the key difference:

• TSA PreCheck speeds up security screening before departure from U.S. airports.
• Global Entry speeds up customs processing when entering the U.S. from abroad and includes TSA PreCheck benefits.

If you travel internationally even a few times per year, Global Entry may offer better overall value since it includes TSA PreCheck automatically.

If you mostly fly domestically, TSA PreCheck alone is usually sufficient.

Who Is Eligible for TSA PreCheck?

TSA PreCheck is available to:

• U.S. citizens
• U.S. nationals
• Lawful permanent residents

Applicants must pass a background check. Certain criminal offenses, providing false information, or security-related concerns may result in denial.

The program is designed for low-risk travelers, which is why the vetting process exists in the first place.

Is TSA PreCheck Worth It?

For most frequent travelers, absolutely.

Consider how often you fly. If you take three or more round trips per year, you’re likely spending a significant amount of time in airport security lines. Over five years, TSA PreCheck can save you hours—if not days—of waiting.

Beyond time savings, there’s also stress reduction. Moving through security without removing shoes or unpacking electronics makes the airport experience feel smoother and more predictable.

Families benefit as well. Children 12 and under can typically use the TSA PreCheck lane when traveling with an eligible parent or guardian.

If you only fly once every couple of years, the cost may not feel justified. But for regular travelers, the value adds up quickly.

Frequently Asked Questions (FAQs)

1. How long is TSA PreCheck valid?

TSA PreCheck membership is valid for five years from the date of approval. After that, you’ll need to renew.

2. Do I always get TSA PreCheck on every flight?

Most of the time, yes—but not always. TSA occasionally conducts random security checks that may require standard screening, even for approved members.

3. Can I use TSA PreCheck for international flights?

Yes, but only for departures from U.S. airports. TSA PreCheck does not speed up customs when you return from an international trip.

4. Do all airlines participate?

Most major U.S. airlines and many international carriers operating in the U.S. participate, but not every airline is included. Always confirm that your airline supports TSA PreCheck.

5. Is the application fee refundable?

No. The TSA PreCheck fee is non-refundable, even if your application is denied.

6. Can my spouse use my TSA PreCheck?

No. Each adult traveler must apply separately. TSA PreCheck membership is individual and cannot be shared.

7. What happens if I forget to enter my Known Traveler Number?

If you forget to add your KTN when booking, you can usually update your reservation later through your airline’s website or by contacting customer service.

Final Thoughts

TSA PreCheck is one of the simplest upgrades you can make to your travel routine. For a relatively small five-year fee, you gain access to faster lines, less hassle, and a smoother airport experience.
