WarBlaze, I just flew for the first time since starting on vaping. I travel a lot, a whole lot, but usually drive. I recently flew from KCMO to DC for a week and they did not blink an eye at my vaping supplies. I do have the added "benefit" of medical supplies to distract them, but I did not mention them and they didn't either.
The other benefit, don't believe what you hear, vape in the bathrooms of the plane and not a sole will know... Same thing for hotels...
Probably frowned upon, but I decided I was willing to chance the $500.00 fine and vape in the bathroom of the plane, guess what, NOTHING happened... And I have probably spent 10 or more weeks in various hotels since I started, not a one has charged me the $250.00 fee for vaping in the "non-smoking" rooms...
Jus sayin...
