I got caught about five years ago by TSA,the woman handed the shit back to me and said have a nice day,it was only a quarter oz.and it was a domestic flight. That being said,I can tell you as someone who travels for a living,DON'T TRY IT!!! If you get caught and it is a domestic flight it is no big deal actually because it is a simple possession charge but anyone that tries it on an international flight is a damn fool,I fly internationally at least once a month mostly to Colombia and other south american countries and you will get caught,I know very well how the system works due to my travels and I am pretty sure I know how to beat it but I have also seen the inside of third world prisons and would never have the balls to try it.
Mail it or just wait until you get there and buy some.
