E Cigs on planes?

Just curious if you are allowed to use these on planes? Will be flying Allegiant, thanks!

 

When I bought mine, the lady in the vapor shop told me that a friend of hers vaped away for an entire 3 hour flight once. So, technically yes it is allowed but I know that some vapor has an odor to it -- not unpleasant like real cigarettes -- but of whatever flavor liquid you have. I personally wouldn't want anyone to get offended so I wouldn't do it if it were me. I'd just wait until I got off the plane and then fire it up!

 

I believe there is a Dept of Transportation regulation banning e cigs on all domestic flights.

 

Thank you I guess it would not hurt to ask when I get there as well.

 

they were banned from use on all domestic flights in 2011. You can carry them on and use them in most airports in the US but can not use while on a plane.

 

Thank you all, I am glad I asked!
