I've read several posts here about this airline banning e-cigs and that airline banning e-cigs... But, I travel every week and take mine right through (fully assembled and ready to go). Even use it in the line to go through security, at the gate and on the plane itself. No big deal... I just whip it out and use it. Don't even get a second stare from other passengers or employees. Just act like you're SUPPOSED to be doing it and the rest falls right in line. Every once in a great while, I'll have someone ask me if those "things" really work....LOL
