Hey there. I am also an airline employee in Houston. I am at IAH. I have found this thing a life saver. Hopefully I can run into you soon if you are at the same airport. I usually stick with my 3.7 volt at work, but a lot of people have been interested. No such thing as stealth vaping a 6 volts with the Silver Bullet. My only concern is an over achiever in TSA wondering what the little box with a switch and batteries is at airports where I have to do that dance.
