I agree, no need to hide! I travel frequently and have never been stopped for ecigs. Last week, coming in from mexico, they asked to look in my bag, ruffled through everything (and I do mean everything) and pulled out a pair of cutical nippers and said I can't take them on the plane! Go figure, better to replace a pair of nippers than my Ego! I always travel with several mods, paranoid of being seperated from my check-in luggage and being without. I throw everything in a back-pack, chargers, cords, batteries, attys and even my juice box (no juice in it), no problem. I put the juice in the little baggy. It usually takes them a few minutes to look over everything in the xray machine but no problems.
Funny story...when I first started vaping, I took a tin box with literally 10-12 801 battys and attys, I was asked what they were! Maybe just because of the way they were packed. The TSA guy said, "do you know what they do to us?? You know what they look like?" He laughed and passed it on. I pack it different now, just to save time.
DSHACK- Just remove the battys and atty and I doubt it would even be noticed.
I really don't think it's considered a "not on the plane" item and IMO, they can't stop you from taking it. I stelth vape the whole trip too. Makes flying alot nicer!
