CLEAR and TSA PreCheck both get you through airport security faster, but they shorten different parts of the line. TSA PreCheck, run by the Transportation Security Administration, lightens the physical screening itself: shoes stay on, laptops and liquids stay in your bag. CLEAR Plus, a private biometric service, replaces the ID-check line with a fingerprint or iris scan and walks you to the front of the screening queue. Because they attack separate bottlenecks, plenty of travelers carry both.
The Core Difference in One Paragraph
PreCheck changes what happens at the screening machine. After a background check at enrollment, you get a Known Traveler Number that links to your reservation and prints a PreCheck indicator on your boarding pass, routing you into a lighter-touch lane where you keep shoes, belts, and light jackets on and leave electronics and liquids packed.1Transportation Security Administration. TSA PreCheck2Transportation Security Administration. TSA PreCheck FAQ
CLEAR Plus changes what happens before you reach the machine. Instead of waiting to show a TSA officer your ID and boarding pass, you step to a CLEAR kiosk, verify your identity biometrically, and a CLEAR employee escorts you to the front of the screening line.3Transportation Security Administration. TSA PreCheck Enrollment and Renewal Provided by CLEAR Once you get there, though, you go through standard screening unless you also have PreCheck. Shoes off, laptop out, liquids in a bin.
That’s the whole comparison in mechanical terms. PreCheck without CLEAR: normal ID line, easy screening. CLEAR without PreCheck: no ID line, normal screening. Both: skip the ID line and get the easy screening too.
What They Cost
PreCheck is a one-time fee for five years of membership. Through IDEMIA, the longest-running enrollment provider, new enrollment is $76.75 and online renewal is $58.75.4IDEMIA. Apply for TSA PreCheck – Enrollments and Renewals Other approved providers, including CLEAR and Telos, run slightly higher, with new enrollment reaching about $85 and renewals from $66.75 to $79.95 depending on whether you renew online or in person.2Transportation Security Administration. TSA PreCheck FAQ That works out to roughly $12 to $17 per year.
CLEAR Plus is $209 per year at the standard rate. United MileagePlus members pay $199, and United Premier 1K members pay $129. Adding family members or friends to your account costs $125 each, up to three additional adults, and children under 18 use the CLEAR lane free with an enrolled parent.5CLEAR. The CLEAR Family Plan
Several premium travel credit cards reimburse the CLEAR Plus fee. American Express offers up to $209 in annual statement credits for CLEAR Plus on eligible cards, including The Platinum Card, the Green Card, the Business Platinum Card, and the Hilton Honors Aspire Card.6American Express. CLEAR Plus Membership Travel Benefit If a card in your wallet already covers it, the effective cost drops to zero, which changes the decision.
Where They Work
PreCheck operates at over 200 airports with nearly 100 participating airlines.1Transportation Security Administration. TSA PreCheck Effectively every major and midsize U.S. airport has a PreCheck lane, and the airline list covers almost any carrier you’d fly domestically or out of the U.S. internationally.7Transportation Security Administration. TSA PreCheck Participating Airlines
CLEAR Plus is at 59 airports, concentrated in larger metros and major hubs. If your home airport and typical destinations are on the list, the membership can pay for itself in saved time. If you fly mostly out of smaller regional airports, you’ll rarely see a kiosk, which makes $209 a year hard to justify.
One caveat worth knowing about PreCheck: it isn’t guaranteed on every trip. TSA uses randomized, unpredictable measures, and any traveler can be routed through standard screening regardless of membership.2Transportation Security Administration. TSA PreCheck FAQ Most members get the expedited lane the vast majority of the time, but the occasional standard-screening trip isn’t an error.
Who Can Enroll and How
PreCheck is open to U.S. citizens, U.S. nationals, and lawful permanent residents.8Transportation Security Administration. Who Can Apply for TSA PreCheck You start online, then book an in-person appointment at an enrollment center for fingerprints, document verification, and a short background interview. The appointment itself usually runs about ten minutes.
CLEAR Plus is open to U.S. citizens and legal permanent residents 18 and older with a valid government-issued photo ID, and to citizens of select international countries traveling on a valid passport, giving it a slightly wider eligibility pool.3Transportation Security Administration. TSA PreCheck Enrollment and Renewal Provided by CLEAR Registration starts online and finishes at a CLEAR kiosk the next time you’re at a participating airport, with no separate appointment to schedule.
Traveling With Kids
Children 12 and under can use the PreCheck lane with an enrolled parent or guardian whose boarding pass shows the PreCheck indicator. Teens 13 to 17 need the indicator on their own boarding pass, which requires being on the same reservation as the enrolled parent.9Transportation Security Administration. TSA PreCheck for Families
CLEAR is simpler for families: anyone under 18 accompanies a parent through the CLEAR lane free, no enrollment required.5CLEAR. The CLEAR Family Plan
Stacking Both
The fastest route through security uses both. You verify at the CLEAR kiosk, get walked past the ID line, and step straight into the PreCheck lane, where you keep everything packed and everything on. At a large hub during peak season, the combination can turn a 45-minute security experience into five minutes.
Whether the stack is worth it comes down to how often you fly and from where. PreCheck alone, at roughly $15 a year, is close to automatic for anyone flying more than a couple of times annually. Adding CLEAR at $209 a year mostly pays off for frequent travelers at busy hubs, or for anyone whose credit card already covers the fee.
What They Do With Your Biometrics
Both programs collect sensitive data, and the handling differs.
PreCheck collects fingerprints at enrollment, and those prints don’t stay only with TSA. The FBI may retain them in its Next Generation Identification system and runs recurrent criminal history checks throughout your membership. TSA also shares biometrics with the Department of Homeland Security’s biometric identification system for ongoing vetting tied to criminal history, lawful presence, and terrorism ties.10Federal Register. Revision of Agency Information Collection Activity Under OMB Review – TSA PreCheck Application Program
CLEAR collects fingerprints, iris scans, and facial images. The company states that it does not sell biometric or sensitive personal data and says it discloses personal information only when required by law or legal process.11CLEAR. Privacy Policy – Your Privacy Matters PreCheck data sits with federal agencies operating under established legal frameworks; CLEAR data sits with a private company operating under its own privacy policy. Different risk profiles, not a clean better-or-worse.
REAL ID Applies Either Way
Since May 7, 2025, federal REAL ID enforcement means you need a REAL ID-compliant driver’s license, state ID, or another acceptable form of identification to clear airport security for domestic flights.12Transportation Security Administration. REAL ID Neither PreCheck nor CLEAR removes that requirement. Both programs require compliant ID to enroll and to fly. If your state-issued ID lacks the REAL ID star, handle that before deciding which expedited program to join.
