) Anyway, I bought a little 510 stick with clearomizers filled em up and threw the juice, charger, accesories in a zip lock baggie and put it in my suitcase. As for the pv itself i put it in a metal cigar tube and put it in my pocket in case of leaks. When i got to the security area i was thinking that it had to look suspicious under the xray. Not a problem, I actually went through the xray a few more times with it getting back on the ship whenever i left. 
Gotta love kids!
