Did you mention to the agent that they state it’s allowed on their own website? Speak to another agent and direct them to their own website. If they insist ask to speak to their manager.
Or just take it with you and print out their own policy and the TSA page just in case (probably a good idea either way).
Or use another airline. I know from experience that Delta and United allow vapes.
Or ship your spare device (if you have one) to your destination a couple of days before you’re expected to arrive.
Check TSA guidelines before going on your flight. Here is my response to a thread on /r/electronic_cigarette, but it’s always a good idea to double check the guidelines prior to flying:
I’ve been on about a dozen flights with all of my vape gear and I’ve not once been questioned about any of it. Here is what I do:
MUST go in your carry-on – Mods and batteries (any spare batteries should be in cases, obviously). If you put either of these items in your checked luggage don’t expect to have them when you pick your baggage up from the baggage claim.
MUST go in your checked – If you are a rebuilder, like myself, scissors larger than 4" and wire snippers (alternatively to wire snippers you can use fingernail clippers and carry them on or check them, which is what I do).
Can go into either your carry-on or checked luggage – RDAs, Tanks*, RTAs*, juice**, battery chargers, other building materials (wire, cotton, tweezers, scissors under 4", etc).
* Most people suggest emptying the juice out of tanks/RTAs before you go through the TSA checkpoint. I don’t. I just unscrew the tank/RTA from my mod and put it in the ziplock with all my other liquids.
** If you are putting your juice in your carry-on your juice must be in bottles less than 3.4oz, which is equal to 100ml, and must be in a single quart sized ziplock style bag. Now, I never bring 100ml bottles with me even though they are allowed. I don’t want it to be confused for something larger than it actually is. I only bring 30ml bottles. If all you have is 100ml or 120ml bottles I suggest getting some 30ml or 60ml unicorn bottles and transferring your juice in larger bottles to those.
Well, when the poop does finally hit the fan with the airlines concerning vape stuff… if you have the time, rail travel is the way to go! Just took a 24 hour train ride (one way) to see my Moms… great experience, as always. Ninja vaped the whole way with no problems!
Suggestion, though… spring $$$ for the business class car ticket; it’s like a morgue on that car… clean and quiet!
I fly all the time on all airlines with multiple mods. Carryon only. My liquid and tanks go in my liquids bag. I generally pull my 2-3 travel mods out of my UD vape bag…when I don’t they usually swab that bag, which is inevitably coated in juice.
When they swab it, the glycerin (or something) always sets off their testers and then you get the mother of all pat-downs…I generally ask them if I’m in the normal range, um, sizewise. It makes them laugh. . .sometimes.
Anyway, I do this internationally and have for…damn 4 years. Pulling your mods out of the bag lessens the probability of getting the pat-down. I’ve got a KTN now, so we will see how it goes in the TSA Pre-check line…
And a lot of the Amtrak employees vape. They don’t stop the long distance trains very often, about every 3-4 hours. My daughter flew with lots of vape gear and a lot of liquid last spring.
Last summer I had to fly on a few flights to go on a Carnival cruise. I was worried about the mod thing to,so I went and bought a padded self addressed envelope had it in my carry on so if they gave me a hard time I could at least mail it back to myself.I had 2 mods with batteries in check on with batteries wrapped separately. I didn’t have any problems. Everyone that vaped on the cruise were bummed they didn’t bring their stuff. So maybe give it a try.
I’m glad this thread got started as was just getting ready to ask the same questions. I’m gonna be flying to Orlanda from Pittsburgh, so only a US flight and couldn’t find the information about transport. I’m only flying 1 way and renting a car to travel and then return with is why I was concerned. Whew…thanx OP for this thread!!!
