You do not need both — they serve different purposes and work together, not as alternatives

CLEAR is a biometric identity verification service that scans your eyes or fingerprints to confirm who you are. TSA PreCheck is a background check program that lets you go through a faster security line. CLEAR gets you to the front of the security queue; TSA PreCheck gets you through the screening itself faster. Many travelers use both because they stack — CLEAR moves you ahead, then TSA PreCheck speeds up the actual screening — but you can use either one alone, and many people do.

The choice depends on how often you fly, how much you value speed, and your budget. CLEAR costs around $189 per year (prices vary by airport and membership type). TSA PreCheck costs $78 to $85 for five years, or about $16 per year. If you fly once or twice a year, TSA PreCheck alone probably saves you enough hassle to justify the cost. If you fly monthly or more, adding CLEAR can cut your total security time to five minutes or less.

Key Takeaways

  • CLEAR uses biometric scanning (eyes or fingerprints) to verify your identity and move you to the front of the security line; TSA PreCheck uses a background check to let you keep shoes and belt on and use a faster screening lane.
  • You can use CLEAR alone, TSA PreCheck alone, or both together — they are not mutually exclusive.
  • TSA PreCheck is cheaper and covers five years; CLEAR is more expensive but saves time at every airport every time you fly.
  • CLEAR is most valuable if you fly frequently (monthly or more); TSA PreCheck is worth it if you fly a few times a year.
  • If you have a TSA PreCheck membership, CLEAR will automatically integrate with it and give you access to the PreCheck lane after biometric verification.

How CLEAR and TSA PreCheck work separately

TSA PreCheck is a background check program run by the Transportation Security Administration. When you are approved, you receive a Known Traveler Number (KTN). You enter this number when you book a flight, and TSA flags your reservation. At security, you go to a dedicated PreCheck lane where you can leave on your shoes, belt, and light jacket; keep your laptop and liquids in your bag; and move through screening faster. The screening is still thorough — you still walk through a metal detector or body scanner — but the process is streamlined.

CLEAR is a separate service run by a private company (also called CLEAR). It uses biometric data — either an iris scan or fingerprint scan — to verify your identity when ready. When you arrive at the airport, you find a CLEAR kiosk (usually near the security entrance), scan your eye or finger, and CLEAR confirms who you are. A CLEAR agent then escorts you to the front of the security line, ahead of everyone else, including TSA PreCheck members. You still have to go through the actual security screening, but you skip the wait.

What happens when you use both together

If you have both CLEAR and TSA PreCheck, the two services work in sequence. You arrive at the airport, use CLEAR to verify your identity and jump to the front of the line, and then enter the TSA PreCheck lane for faster screening. The result is the shortest possible security experience: no waiting in the main line, and no removing shoes or electronics.

CLEAR automatically integrates with your TSA PreCheck membership — you do not have to do anything to link them. When CLEAR verifies your identity, it passes that information to TSA, and you are routed directly to the PreCheck lane. This integration is why many frequent travelers find the combination worthwhile: CLEAR eliminates the line, and PreCheck eliminates the hassle of the screening itself.

CLEAR is available at major airports; TSA PreCheck is available at most U.S. airports

CLEAR operates at about 50 airports in the United States, mostly major hubs like Atlanta, Los Angeles, New York (JFK, LaGuardia, Newark), Chicago, Dallas, Denver, and San Francisco. If you fly out of a smaller airport, CLEAR may not be available there. You can check CLEAR's website to see which airports near you have the service.

TSA PreCheck is available at over 200 U.S. airports, including most regional airports. If you fly domestically, you will almost certainly have access to a PreCheck lane. This wider availability is one reason TSA PreCheck is a safer bet for most travelers — you can use it almost anywhere in the country.

Cost comparison and how often you need to fly for each to pay off

TSA PreCheck costs $78 to $85 for a five-year membership, or roughly $16 per year. The time savings per trip is modest — maybe 5 to 10 minutes — but it adds up if you fly several times a year. If you fly four times a year, you save 20 to 40 minutes annually for $16, which most people find reasonable.

CLEAR costs around $189 per year, though some airports charge slightly different rates and discounts are sometimes available. The time savings per trip is larger — often 10 to 20 minutes, depending on how busy the airport is — but the cost is higher. If you fly 12 times a year (once a month), CLEAR saves you roughly 120 to 240 minutes annually, or 2 to 4 hours. Whether that is worth $189 depends on your schedule and how much you value your time.

Some people bundle the two: they keep TSA PreCheck active for the five-year term and add CLEAR during months when they know they will fly frequently, then pause it during slower periods. CLEAR allows you to pause and resume your membership, so you can adjust based on your travel plans.

Who should get TSA PreCheck, and who should add CLEAR

Get TSA PreCheck alone if you fly a few times a year (two to six trips), do not mind waiting in line, and want to avoid the hassle of removing shoes and electronics. The cost is low, the benefit is real, and it works at almost every airport. This is the choice for most casual business travelers and families who take an annual vacation.

Add CLEAR if you fly monthly or more often, travel during peak hours (early morning, evening, holidays), or have a tight connection and cannot afford to wait in a security line. CLEAR is also worth it if you travel with young children or have mobility issues and want to minimize time standing in line. The higher cost is offset by the consistent time savings across many trips.

Get both if you fly frequently (monthly or more) and value speed and convenience above cost. The combination gives you the shortest possible security experience and is standard practice among business travelers and frequent flyers.

Get neither if you fly rarely (once a year or less) or have a very tight budget. The time savings will not justify the cost, and you can still get through security reasonably quickly, especially if you arrive early.

How to sign up for each service

To sign up for TSA PreCheck, visit the official TSA PreCheck website (tsa.gov/precheck). You will fill out an online form with your personal information, pay the fee, and schedule an in-person appointment at a TSA PreCheck enrollment center. The appointment takes about 10 minutes and involves fingerprinting and a background check. You will receive your Known Traveler Number (KTN) within days, and you can start using it when ready when you book flights.

To sign up for CLEAR, visit the CLEAR website (clearme.com). You will create an account, provide your personal information, and schedule a biometric enrollment appointment at a CLEAR kiosk at a participating airport. The appointment takes about 5 minutes. You will receive your CLEAR membership when ready and can use it the same day. If you already have TSA PreCheck, CLEAR will ask for your KTN during enrollment so it can link the two accounts.

Frequently Asked Questions

Can I use CLEAR without TSA PreCheck?

Yes. CLEAR gets you to the front of the line, and you will still go through standard security screening. You will need to remove your shoes, belt, and electronics. It is less convenient than using both together, but CLEAR alone still saves significant time by eliminating the wait.

Can I use TSA PreCheck without CLEAR?

Yes. TSA PreCheck alone is the most common choice for casual travelers. You will wait in the regular security line, but once you reach screening, you move faster because you can keep shoes and electronics on. Most people find this balance worthwhile.

If I have CLEAR, do I automatically get TSA PreCheck benefits?

No. CLEAR and TSA PreCheck are separate programs with separate fees. However, if you have both, they integrate automatically — CLEAR verifies your identity and routes you to the TSA PreCheck lane. You must pay for and enroll in both to get the combined benefit.

Does CLEAR work internationally?

CLEAR only works at U.S. airports for domestic flights. For international travel, you may be able to use TSA PreCheck if you are flying out of a U.S. airport, but CLEAR does not explore once you leave the country. Some other countries have their own trusted traveler programs, but they are separate from CLEAR.

What if I lose my CLEAR or TSA PreCheck membership?

If your CLEAR membership expires or is revoked, you lose access to the biometric verification service and the front-of-line benefit. If your TSA PreCheck is revoked, you lose the PreCheck lane access. Both programs have appeals processes if you believe a revocation was made in error. You can contact each program directly to understand why your membership was affected.
