@Bebop thank you! I don't blow clouds in public anyway, and the airport I'm flying out of luckily allows vaping in all terminals when I checked earlier. I don't know about the other ones, but I'm hoping they do too.
@Tam thanks for the advice! I checked with where I'm flying out of so far, and they allow vaping in all terminals. I usually don't blow clouds in public, I try not to bug anyone with it or make it noticeable.
@BirdDog thank you! I'll have to check out their guidelines. I didn't think it would be a problem, and I'm glad to hear it isn't. TSA is a ***** at my airport so I hope they won't stop me just for the hell of it. It's happened before because I have metal rods drilled into my entire spine and the person had some weird thing against me being disabled.
