Just in case you're traveling for an extended period of time, you can put as much juice as you want in your checked luggage. Just seal it up well so if the liters of juice start to leak you don't mess up all your clothes. You can also put as many mods and tanks you can cram in there as well. You just can't put batteries in checked luggage.
That's interesting. For some reason I always thought the quart bag in carry-on was all you got.
I wonder if you could get away with putting bottles of 100mg nic in checked baggage. Do you know if there any specific rules about that? Doesn't seem like there's any basic difference between 10mg flavored juice and 100mg unflavored juice unless they specifically say there is. I know there are people who actually vape up to 50mg juice.
It would have to be packed to withstand all the stuff airlines do to bags, like in heavy duty plastic bottles in bubble wrap. Probably in a rigid suitcase. And labelled as e-juice in case they did a random bag check on it. If a bottle of 100mg broke it would put out some pretty noxious fumes. I get a picture of customs agents lying on the floor gasping and choking, and me being led away in chains by guys in biohazard suits.
Always assumed if I moved from US to UK I would have to leave my nic stash behind. Maybe I could dilute it down to 50 and take some with me. Even diluted down to 20mg I could take a useful amount. Or put it in the shipping crates I would be having sent over. That's got me thinking.
