Agree with the above especially the point of the Coolfire 2 (who the BLEEP thought it would be a good idea to design a mod that looks like a hand grenade anyway?).
Remove the batteries, juices in your ziplock, empty atties if possible if not they go in the baggie too, and slide on through.
Side note about atties. I do try to fly with my atties empty as the change in cabin presure will make many leak. If you have to you have to, I just wouldn't suggest filling them up before your trip thinking it will be super convenient to be able to just throw them on your mod and vape when you get where you're going. More than likely you'll have to rinse off everything that was in your ziplock, wipe down your atty or even remove the coil so you can blow it out, etc. which can be a total pain.
