Just got back from Kodiak, AK round trip from Pensacola. I carried on 3 Ego Twist, a VAMO, several Vivi Novas, and a half dozen 30ml bottles of juice. I was able to vape without hassle in P'cola, DFW, Portland, Seattle, Anchorage and Kodiak. No one gave me a second look. TSA knew what my gear was and was not impressed or alarmed. One guy in Kodiak had to explain to his partner what it all was, but was cool about it. I do not suggest vaping on the plane. I didn't even want to go there. Hope my input helps.
