As E-Cigarettes and Vaping have become more common, there is some confusion as to the rules of how to pack your e-cigs, Juuls, and vape pens and juice when flying. It gets more complicated as individual airlines have their own rules for flying with e-cigs and vape pens, with may differ from those set out by the FAA, TSA, and CATSA.
Be sure to note that no matter the country or airline, NO SMOKING and NO VAPING rules apply on all flights, so no vaping on any airplane. This includes in the lavatories.
The TSA and FAA prohibit any electronic cigarettes or vaping devices in checked baggage. This ban is due to the batteries in the devices and the risk of fire from these devices in the baggage hold. Battery-powered E-cigarettes, vaporizers, vape pens, atomizers, and electronic nicotine delivery systems may only be carried in the aircraft cabin (in carry-on baggage or on your person). Remove all electronic cigarette and vaping devices from carry-on bags if checked at the gate or planeside.
Flying with Marijuana/Cannabis?
Take a look at the Flying with Marijuana - Rules for Flying with Cannabis page for rules and laws about flying with Medical Marijuana, Recreational Cannabis, and Edibles in both the USA and Canada.
Because vaping liquid or juice is a liquid, it falls under the TSA's 3-1-1 Liquid Rules. This means that you may bring it in your carry-on, but it is limited in quantity to a bottle no larger than 3 oz, packed into a 1-Quart transparent plastic / ziploc bag. Only one of these bags is allowed to be brought through security.
If bringing more than 3 ounces of vaping liquid, you will have to pack this separately into your checked luggage. If this is the case, just keep in mind that the vaping pen must still be carried with you on your person or in your carry-on.
We recommend a Smell Proof Bag, such as the Helmet Head Smell Proof Case
NO! Like smoking, it is strictly prohibited to vape or smoke electronic cigarettes while on the plane. You may not turn on your vape pen while on the plane, and it is also prohibited to charge your e cigarette while on board the plane. We recommend disconnecting the battery from the vape pen before boarding the airplane, so it does not turn on accidentally.
Individual airlines have varying rules for flying with electronic cigarettes and vape pens, some of which are stricter than the TSA and FAA guidelines that set out what can and cannot be brought through security. Be sure to check with your specific airline for their rules regarding carrying electronic cigarettes onto the plane.
If travelling internationally, be sure to check the rules and laws regarding the country you are visiting, as vapes and electronic cigarettes may be banned or treated differently in the country you are visiting. Some countries have recently banned the entire electronic cigarette industry, and you may get into trouble with local police if caught with a vape pen or electronic cigarette on your person.
