How to transport my weed across state lines?

Ok so im flying out to missiouri in two weeks and want to get four joints out there but idk how i would do it. It was either find some way of getting on my flight with me (checked or carryon) or fedexing it to myself but ive never done either and could use someone with experience to help. All i need to do is get four joints from here in new hampshire to missiouri for my vacation. Also getting somethere is pretty much out cause ill be with my family the whole time i wont be able to leave to go find some. At most ill be able to go out in the back field play guitar and smoke up. So anyone that could help me out would be awsome thanks!
