I understand that it needs to be in hand luggage. BUT am rather alarmed that spare coils show up as bullets (apparently) on the screeny thing. I won't be able to buy abroad. Also, does all the e juice have to go in hand? It might be so much easier to just smoke abroad but I don't want to. Gave up on the 20th March so not doing too bad.
Just empty out the liquid from the tank and put the liquids in clear plastic bag. There won't be any other problems. I have done it several times to lots of countries. (keep in mind they are illegal in some countries)
