On a plane all my e-liquids are in bottles in a quart size bag....even my filled Aspire Nautilus tank. Just before boarding I go to the bathroom and clean my tank out and dry it with paper toweling.
When landing and taxing to the gate I refill my tank and it's ready to go once I get off the plane.
As long as the caps are on tight the bottles won't leak.
I have taken a Provari, ZNA, 8 16850 batteries in cases, several
tanks, coils, battery charger and a lipo bag in my carry on. I only pull out my quart size bag of
e-liquid, and my battery cases and place them in the bin.
I keep my Provari and ZNA in the original box....never taken them out of my carry on and have never been stopped or questioned.
Good Luck to You!!
