I'm going to be flying for the first time with my IBTanks. If I have loaded tanks stashed in their Thingy can I just put them in my 3-1-1 bag with other liquids? On another note, what if I check my bag with the Thingies containing the loaded tanks? Will I have leakage problems due to the pressure changes? I guess I'm also concerned about the extra e-liquid. I would imagine it also just goes in the 3-1-1 bag. Anyone with experience with this. This is all in-country here in the U.S.
