What do TSA PreCheck members wish they'd known before applying?

What's the biggest TSA PreCheck mistake?
The biggest mistake is assuming PreCheck works automatically. You must add your Known Traveler Number to every airline reservation, and even then, the airline has to put the marker on your boarding pass. If you skip that step, you'll be stuck in the regular line. Always check your boarding pass for the PreCheck logo before you head to security.
How do you decide if TSA PreCheck is worth it?
- Count your flights in the last 12 months; if fewer than 4, skip PreCheck.
- Check if your usual airline participates in PreCheck (most do, but not all).
- Book your enrollment appointment now, but expect 3 to 4 weeks total from application to approval.
- After approval, add your Known Traveler Number to every reservation and verify the PreCheck logo on your boarding pass.

How long does the appointment take?
About 10 minutes, once you're in line. The whole thing, from walking up to walking out, usually lands under 15 minutes. The wait before you get to the counter is what varies.
Does PreCheck work for kids?
Yes, kids under 13 ride free on your PreCheck. They don't need their own membership; they use your Known Traveler Number when you book. Once they turn 13, they need their own application.
Is Global Entry worth the extra cost?
Yes, if you fly internationally even once a year. Global Entry costs $120 for five years and includes TSA PreCheck, so the real question is whether you cross borders enough to use the kiosks.
