I just flew home Sunday from Ft Hood TX after being there for my son's home coming from Iraq after a year (YAY FOR HIM AND US!)
Anyhoo......he flew with his PV from Iraq, NO problems. I flew home, Jet Blue, again no problems. I packed my battery charger and batteries in a make up type bag in my carry on, juice in the quart zip lock bag, and PV right in my purse, all assembled. Not a peep from security or anyone else for that matter.
If you want a good laugh, my fiance isn't quite on the PV yet, but still smokes analogs. He was outside in the freezing 30 some degree weather getting a last "fix" while I sat inside, right next to a TSA agent and puffed away. I was fine, fiance was frozen....lol
On the plane I pulled out the PV and vaped away when I felt the need. I put the air vent on full blast, and when I exhaled downward the vapor just disappeared. My fiance kept giving me dirty looks and telling me to "put that away..." before I got caught...lol
After about 30 min my fiance gave in and asked if he could use my PV. We both happily vaped the rest of the trip with no troubles at all. Of course we didn't blow clouds up into the air, and if we saw a flight attendant heading towards us we just didn't take a draw, but all in all there were NO problems with gear or use.
I like to drip too, but I just pre-filled a couple of carts for travel. It was easier that way. Oh, and the whistle tip carts will draw more attention than the round tip carts. Those round ones on a solid black 510 look just like a pen. No problems at all.
Gotta love my PV!
