I am really new to vaping (about 10 days), and I've asked a few posters here about their experiences with public vaping and vaping while traveling.
I following the typical TSA regs about liquids (2 30ml juices and a full tank) in the quart sized zip lock, and breezed through security without a single issue.
I sat in the terminal 3/ concourse b food court at CVG and vaped openly while reading for 40 mins without a single question or comment. I did notice a few people walk "closer", and were obviously sniffing the air, but no one said or did anything.
At the moment, I'm sitting in a common eating area at Hartsfield Jackson Intl Airport in Atlanta (concourse b). I have been vaping quasi-discreetly for the last 30 minutes, and haven't encountered a single issue! There was even a young lady (non-smoker, I couldn't smell her. Lol) sitting right beside me eating her lunch without paying me any mind at all.
Just wanted to pass along my experiences and say that vaping is becoming a better and better decision for me with every passing day!
