I've taken weed on planes several times using a similar method each time. I always use some type of check bag whether it be clothes, or my golf bag. First I'll seal it well in a rolled baggie, then throw it in a small zip lock and bend it in half so its about the length of your thumb and however fat. Next I find some place within something within something....(two socks rolled into eachother-put it in one sock, gum package in a jean pocket, golf glove in a golf bag pocket and more). It seems risky but I have become very comfortable doing so flying out of several airports all up and down the Eastern states, never had a problem. Throw a stick of deodorant next to it if it makes you feel better about the chance of smell. Even nowadays when they place your bag in the giant scanner all it really does is scan for hazardous materials, none of which are in the fire im burning on. Be confident, fly, and get high.
