dont know about the airport but sending a controlled substance through the mail is deff a felony busy travel times and days are better i went through customs last thanksgiving and it was so crowded they were waiving every one through as soon as you showed your passport i would vacum seal and place in your checked luggage take a speed stick type deoderant roll the contents all the way out and place weed inside bottom of container and then replace the contents you will have to cut it down a little to allow for the weed in the bottom this is still not 100% safe so try at your own risk but so far it has served me well good luck
