Under current U.S. air-safety rules, vaping devices and spare lithium batteries must travel on your person or in carry-on baggage. They are not permitted in checked baggage. The device must be protected from accidental activation, and it cannot be used or charged on the aircraft.
Check the FAA, TSA, airline, destination, and local rules again before every trip because requirements can change.
Pack the device in your carry-on
Turn it off or lock it and use a case that protects the button or draw sensor. The FAA lists measures such as removing the battery, separating it from the heating coil, or using a protective cover or lock.
If your carry-on is taken for gate checking, remove the vape and spare batteries before handing over the bag.
Protect spare batteries
Spare lithium cells must remain in the cabin and be individually protected from short circuits. Keep them in retail packaging or a proper battery case so their terminals cannot touch coins, keys, or other metal.
Damaged or recalled batteries should not travel.
Do not charge or use it in flight
The FAA prohibits charging vaping devices or batteries aboard the aircraft. Vaping is also prohibited. If a device overheats, smokes, or catches fire, alert the cabin crew immediately.
Prevent liquid leaks
Cabin pressure changes can push liquid through a pod or tank. Emptying the tank where practical, closing ports, keeping the device upright, and placing it in a protective leak-resistant bag can limit the mess. Follow airline liquid rules for bottles carried through security.
Check the destination
Possession, import, flavor, and use rules vary by state and country. An item allowed in your U.S. carry-on may be restricted at the destination. Use official government and airline sources, not an old forum post.
Before leaving home
- Put the device and batteries in carry-on baggage.
- Lock or deactivate the device.
- Protect every loose battery terminal.
- Do not pack damaged equipment.
- Recheck the airline and destination rules.
