Can I take electronic cigarettes on board with me on the plane? And the battery?
The answer is yes you can! You will have to place your eliquid in a clear plastic bag for the security gate.
Am I allowed to vape in the airport and during the aeroplane flight?
Many airlines advise that they will not permit you to vape unless you vape in a designated smokers area. However they do permit you to carry your electronic cigarette and e-liquid onboard.
How much electronic cigarette eliquid can I carry in my hand luggage?
Quantity restrictions on the amount of ejuice you are permitted to carry onboard still apply, so the usual liquid quantity restrictions apply for e-liquids as they do for other liquids.
