I've gotten on planes a bunch of times with weed. The first time was with my second wife coming back from Jamaica, we purchased too much to smoke, and didn't want to leave the half oz. there (it was just too fucking good). She put it in a little black plastic bag and rolled it tight, she then put that into another small plastic bag and rolled it tight. She did this 4 times then put 3 rubber bands around it, it ended up looking like a cigar. She then put that into a full shampoo bottle so no weed molecules could leak out. I thought it would be soaked with shampoo when we got home, but the shampoo only got through the first two bags and left the last two dry. Nobody could believe the quality of this weed.
When I'm flying somewhere, this is what I do: I get few hangers from the dry cleaners, the ones with the hollow, cardboard tube across the bottom. I carefully remove the tube and open one end, then I start shoving in tiny buds/shake and start packing it down with a thin dowel. Once it's tightly packed (I usually fit an eighth in easily) I then open the other end and shove in a foam earplug and do the same for the other side, close up the ends, and make it a hanger again. I hang my collared shirts on those buttoned all the way up. The weed can be a real bitch to get out of the tube, sometimes it's easiest to just break it in half and spill it out. I only do this with my carry on, never check those bags. I never had a problem, but once had a REALLY close call: I was at a tiny airport out east that I drove into, and only had a one way ticket. I was 'randomly' taken out of line to have my bags checked, I think the one way ticket sparked that. The guard and I spoke casually about random shit while he took out the shirts one by one, he even checked their pockets! No problems, I packed it up and got on my plane...
