I was wondering if anyone has had problems flying with their ecig. I plan on traveling with one complete filled 510 on me and packing everything else (liquid, battery, charger). I'm a little concerned about having it confiscated while going through the security check. I don't plan on using it on the plane, or even in the airport. I just want to have it on me when landng. Any info would be appreciated. BTW-I'm flying within the continental US if that makes a difference.
