TSA PreCheck vs Global Entry vs CLEAR: the actual math

Airport line-skipping has become a three-way subscription decision, and the marketing works hard to blur what each product does. The short version: TSA PreCheck makes the security screening itself faster and gentler. Global Entry speeds you through US customs when returning from abroad — and includes PreCheck. CLEAR doesn't change screening at all; it moves you to the front of the line for the ID check. One is priced like a utility, one is a bundle, and one costs more than the other two combined.

What each program actually is

The first decision is nearly automatic: if you ever fly internationally, buy Global Entry, not standalone PreCheck. For $42 more over five years — $8.40 a year — you get everything PreCheck does plus a customs re-entry that takes two minutes instead of a 45–90 minute arrivals-hall line. Even one international trip per five years justifies the difference. The application takes longer (background check plus an interview, though 'Enrollment on Arrival' lets you do the interview when landing from a trip), but the value is lopsided.

Pricing your time in line

PreCheck's math is almost embarrassing. Say it saves a conservative 15 minutes per trip through security, and you take six round trips a year — twelve screenings. That's three hours a year for $16: about $5.30 per hour saved, before counting the unmeasurables like keeping your shoes on and not decanting your bag onto a conveyor. If your time is worth anything at all to you, PreCheck clears the bar at even two or three trips a year. It also removes the need to arrive as early, which compounds the savings.

The logistics, so they don't stall you

PreCheck enrollment is a 5-minute online application plus a 10-minute in-person visit (many Staples and IDEMIA offices do it), with approval typically in 3–5 days. Global Entry adds a deeper background check and an interview; conditional approval can take weeks to months, but 'Enrollment on Arrival' lets you complete the interview at passport control when landing from any international trip — no appointment needed. Two mistakes cost people their benefits after enrolling: forgetting to add the Known Traveler Number to airline profiles and existing reservations (no KTN on the booking, no PreCheck on the boarding pass), and letting the name on the application differ from the name on tickets — a mismatched middle initial is enough to silently drop the benefit. Fix both once, set a renewal reminder for year five, and the system stays invisible for the rest of the membership.

CLEAR: when $199 makes sense (and when it doesn't)

CLEAR replaces the document-check queue with a biometric pod and an escort to the front of screening. Stacked with PreCheck, it means front-of-line access to an already-short line. At full freight — $199 a year, versus $24 a year for Global Entry — it's hard math for most travelers: PreCheck lines average under 10 minutes nationally, so CLEAR is buying back single-digit minutes, and only at peak times when the line was long to begin with.

Three situations change the answer. First, discounts: several premium credit cards (Amex Platinum among them) rebate CLEAR entirely, and some airline elite statuses cut it to $0–$149 — free is a fine price. Second, home airport: if you're based somewhere PreCheck lines routinely blow past 20 minutes at your usual flight times, CLEAR's front-of-line jump has real value. Third, volume: 25+ trips a year with tight connections makes small per-trip savings add up. Outside those cases, CLEAR is the one to skip.

• Fly 2+ times a year, ever internationally: get Global Entry ($120/5 yrs) and let it carry PreCheck.
• Fly 2+ times a year, strictly domestic: standalone PreCheck ($78–$85/5 yrs) is enough.
• Check your credit cards first — many rebate the PreCheck/Global Entry fee automatically, making this free.
• Add CLEAR only if a card or status makes it free, or your home airport's PreCheck line is chronically slow.
• Add kids strategically: children 12 and under use PreCheck free with an enrolled parent; teens 13–17 can join on the same reservation.

The bottom line

Global Entry at $24 a year is one of the best time-for-money trades in travel, and it includes PreCheck; buy it (or plain PreCheck if you never leave the country) the moment you fly more than twice a year — ideally with a credit card that refunds the fee. CLEAR is a different animal: $199 a year to skip a line that PreCheck already made short, worth it only when it's free via a card or your home airport is a known disaster. Cover the whole household, set a renewal reminder for year five, and stop pricing your own airport time at zero — the lines were always costing you something.
