Airport Bag Hacks from Frequent International Travelers

Use a dedicated tech pouch

Prevent cables and devices from tangling or hiding important documents.

Stash an emergency $20 and credit card separately

For secondary screening or lost wallet scenarios, never store all financial means in one place.

Pack a second pen

Airport pens are often missing, dirty, or out of ink.

Use color-coded pouches

Assign certain colors for documents, medications, or electronics for quick grabs.

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.

Is a printed boarding pass still useful?

Always have a paper backup—scanners, batteries, or apps fail more often than you'd expect.

Where should I put customs forms and a pen?

Easy access pocket or travel wallet—do not bury in your main pack.
