Short answer: For a flight departing the United States, the FAA requires electronic smoking devices in carry-on baggage or on your person, protected from accidental activation. This does not mean every destination permits possession or importation. Check airline, transit-country and destination rules before traveling.

Pack the device for the flight
- Keep the device out of checked baggage, including a bag checked at the gate.
- Protect spare lithium batteries individually against short circuits.
- Do not use or charge a device aboard the aircraft, according to FAA guidance.
- Check separate liquid limits and local laws for every leg of the trip.
The old draft gave a blanket “yes” for international flights. Flight-safety rules and local possession laws are separate questions, and the latter vary by place and date.
Frequently asked questions
Does an FAA-compliant carry-on guarantee entry to another country?
