Personal Bag vs. Carry-On: Where to Store What?
| Item | Personal Bag (Underseat) | Carry-On Luggage |
|---|---|---|
| Passport/ID | Always on you for easy access | Risky—could be overhead or out of reach |
| Completed Forms | Slips into travel wallet or side pocket | Can get crumpled or misplaced |
| Electronics | Top pouch for fast removal in security | Good for backups/chargers only |

FAQ
Bagging Essentials—FAQ
Should I carry my Global Entry card?
Keep it in your personal bag, especially for land crossings and as backup at airports.
Can I keep meds in my personal bag?
Yes, and you should—carry prescription & daily meds in your underseat bag, not checked luggage.
