I keep my air purifier near me in the bedroom, takes care of both vapor and dog dander.
On flying, realistically, after years off of cigarettes, even though I'm a constant vaper I have no problem not vaping when circumstances dictate. A handful of lemon balls, soda water, a headset and a book on my tablet make a flight go by quickly.
When I had a minor procedure last year I had to go zero nic for a couple weeks. In that case I could vape, just no nicotine. I was glad when I could start nicotine vaping again (I do like the minor stimulant effect), but it isn't like I was climbing the walls when I couldn't.
