20. The importance of including your Known Traveler Number

Ever wondered why some travelers zip through security while you're stuck untying your shoes?

The secret could be a Known Traveler Number (KTN). If you've signed up for TSA PreCheck or Global Entry, make sure this precious number is on your boarding pass.

It's like having a magic key to a faster security line. So, double-check your airline profile, or the next time you book a ticket, ensure your KTN is included. It's a small step with big rewards.
