Airport Edge Cases
Weird, expensive, confusing things people travel with — checked against airport security, cabin baggage rules, checked baggage, customs, batteries, biosecurity and destination restrictions.
Tech & batteries
Lithium cells, drones, expensive electronics. Most of this stays in the cabin — checked luggage is where it gets confiscated or catches fire.

Wellness & biohacking
Ozempic pens, peptides, hormones, syringes, supplements. Keep medication labelled, carry a prescription, and check the destination — some countries restrict what your pharmacy sells over the counter at home.

Biosecurity panic
Dairy, meat, honey, seeds, plants. Airport security usually lets these through. Customs at the destination is where they get refused, fined, or seized.

Three rules, one item at a time.
Airport security, airline checked baggage and destination customs are three separate systems. An item can pass security and still get refused at the border — that's why edge cases trip people up.
