Global Entry if you ever fly internationally (it includes PreCheck). PreCheck alone if you only fly domestically. CLEAR only if you fly a lot from airports where it operates and lines are long — it stacks with PreCheck but doesn't replace it.
| Program | What it does | Cost (approx.) | Best for |
|---|---|---|---|
| TSA PreCheck | Faster security lane; shoes, laptops, liquids stay | $78 / 5 yrs | Domestic flyers |
| Global Entry | PreCheck + fast US immigration on arrival | $120 / 5 yrs | Anyone flying internationally |
| CLEAR | Biometric ID check that skips the ID line | ~$199 / yr | Very frequent flyers at CLEAR airports |
Stacking: CLEAR + PreCheck gets you to the front of the ID check and then into the PreCheck lane. Global Entry members also get NEXUS-style benefits into Canada on some lanes.
Tips: many credit cards reimburse PreCheck or Global Entry; Global Entry interviews can be done on arrival at many airports; add your Known Traveler Number to every booking or the benefits don’t appear.

Is TSA PreCheck worth it?
If you fly two or more times a year from US airports, yes: shorter lines, shoes and laptops stay put, and many credit cards reimburse the fee. Global Entry costs slightly more and includes PreCheck plus faster US immigration — the better buy for international flyers. Full answer →
How long does airport security take?
Usually 10–30 minutes, but 45–60+ at large hubs during morning and holiday peaks. Many airports publish live wait times; PreCheck, Fast Track and off-peak departures are the reliable ways to shorten it. Full answer →
