Just got back home(near Phila. Pa. U.S.A.). No real problems to report. I had my Provari, with a DID on top, on me at all times. I just put the atty in an old pill bottle for its ride on the scanners. My juice,extra wicks,and tools all went in small zip bags inside the larger one for carry on. They asked what it was. Then they wanted one, when they watched me put it back together at the end of the line.
I went from Phila. to Chicago, then Liberia Costa Rica. The return was by way of Houston Tx.
In Costa Rica I did not spend much time off of the Four Seasons Papagayo grounds. I was told to use "smoking rules", go outside and stay on the sides. Most of the resort workes wanted a hit untill they found out it was only nic. My vape gear was fine, I was the one that got sick! Best wishes on your travels!!
