I travelled across canada with over an ounce of Purple Kush, and over an ounce of Willy Nelson, along with 4 big bottles of tincture. I began at a 'smaller' airport, only changing planes once and my 'checked bags' went on through... I made it. I was shitting bricks collecting my bags at my final destination, eyeballing the crowd, and damn near running out of the airport. I think I made it due to the following factors:
I pushed it out of my mind ANY time I began to think about it.. (made me look nervous and suspect)
I sealed it in a jar and tried to mask smell further by packing DIRTY laundry around it (inside a bag, so the rest of your clothes don't smell like socks and ginch...
I began at a small airport that RARELY, IF EVER dealt with international flights (no dogs... unless I am super unlucky and get busted the day they are doing some training with the local k9 unit), and my bags were still being re-routed 'domestic', international flights and luggage usually see more anti-drug measures
I was a lucky mutherfucker.
Given more fore-thought... I would fed-ex it. (still using deceptive packaging!!)
