About time for my annual trek to Vegas. Anyone have problems getting thru security checkpoints with Ecigs?

Depends on the operators level of experience with PV's.... If asked, just say exactly what it is.. Of course, you might have to dumb it down some and say it's an e-cigarette...![]()
In more than 3 years, traveling 2-3 times a year, I've never had difficulty carrying on vaping supplies. Liquids in your quart size carry on baggies, the rest of your liquids in checked bags.
BUT (double check this with the TSA regs) I think you have to carry on batteries - i don't think they're allowed in checked baggage.
By batteries do you mean like 18650's etc or ego type or both?
Federal Aviation Administration (FAA) prohibits loose lithium batteries from being transported in checked baggage.
I took my ego-t on a trip to Dallas from Florida and had no issues, also was able to smoke in airport and on the plane with no questions. BUT, I am very careful with 'smoke' coming out, I usually just hold in in for a few seconds longer than normal and no smoke comes out at all- I do it in college classes all the time- most people just think I am playing with a pen lol. I had a friend I have known for almost a year notice smoke come out the other day when we were outside and she had no idea I had been smoking for the last year!
I think the issues come up when people blow an excess of vapor out and it can be mistaken for actual smoke. As long as you are not obnoxious with it I don't see any problem personally.
