There's over a hundred people sharing that space, and we need to be courteous to everyone else for the small amount of time we're crammed together.
The question is: if I am not allowed to bring (potentially expensive and/or hard-to-find) e-cigs on board, what do I do when I land? Can I put them in checked luggage? Do I have to throw them out if I forget they're on me? Too bad?
I don't have any answers but I personally use an e-cig to keep me from going back to the real thing (real cigarettes that is).
How do you think this actually change impacts people _while_ on the plane since vapes have already been banned from carry-ons? Your comment doesn't seem to be relevant to this change.
That's not true. They are allowed on carry-on, but not checked bags. The change only bans their use on planes, not their presence.
