Vaping isn’t allowed on flights domestic & international, here's the low down on vaping when travelling by plane.
The majority of airports have now formed a regulation on e-cigarettes. Depending on your location and desired destination, you may find select designated vaping areas before you board to fly.
PLAN, PLAN & PLAN AHEAD...
The best tip is to research the airport’s rules prior to packing your luggage. Interestingly e-cigarettes, mods and e-pens are not allowed in checked bags and must be taken in your carry-on bags through security. As the clearomisers has a risk of leaking during the flight, maybe empty it before you take-off and pop it into a sealed container to combat the altitude pressure. As for your e-liquids, they will need to be placed in a clear plastic bag as is the case with all other liquids taken through security, with no more than 100ml of liquid inside. Luckily, all our KiK e-liquids come in bottles of 10ml so you can cram as many e-liquids into those handy bags as you like, just don't go overboard.
