Flying and vaping: Everything you need to know (2025 update)

This guide will give you a detailed answer: Can e-cigarettes be taken on airplanes? How to carry and use? What common mistakes should be avoided?

✈ Can I bring e-cigarettes on board an airplane?

Yes, but you must carry it according to regulations.

Most airlines and airport security agencies allow passengers to bring e-cigarettes with them, but they must be carried on your person (in your hand luggage) and not checked in . The main reason is that e-cigarettes use lithium batteries. If stored in checked luggage, they may cause a fire when the pressure changes or short circuits.

✔Carrying method suggestions:

E-cigarette devices should be packed in hand luggage, preferably in a dedicated box or anti-collision packaging.
Never pack e-cigarettes in checked luggage.
It is recommended to shut down the device or remove the battery to avoid accidental startup.

🔋Battery and charger regulations

Electronic cigarettes often use lithium batteries, including 18650, 20700 and other models. According to the International Air Transport Association (IATA) and most airlines:

All spare batteries (not installed in the device) must be carried with you and in their original packaging or short-circuit-proof packaging (such as a plastic box).
Most airlines allow 2 to 4 spare lithium batteries to be carried on board, but the upper limit varies by airline.
If a mobile power bank is used to charge e-cigarettes, it must also be carried by hand.

⛔ Do not charge e-cigarettes during flight.

🧃 Vape Juice Specifications

E-cigarette oil is classified as a liquid and is subject to standard liquid security inspection regulations:

Each bottle should not exceed 100 ml (3.4 oz) .
All liquid containers must be placed in re-sealable transparent plastic bags with a total capacity not exceeding 1 litre.
It is recommended to carry 2 to 3 small bottles of juice as backup to avoid confiscation.
Please do not bring large bottles of juice in your hand luggage as they may be thrown away.

🚭 Can I smoke e-cigarettes on an airplane?

Can't.

Whether on short or long-haul flights, all airlines explicitly prohibit the use of e-cigarettes in the cabin , including in the toilet.

Reasons include:

E-cigarette vapors may set off smoke alarms.
Flight safety and other passenger comfort considerations.
