Putting it in a bag is super helpful, if for nothing else then your handles not being touched, you don't get a million "is that a parachute?" questions. The last time I flew with my rig I didn't have a stash bag for it and just walked on with it. The TSA workers just asked if it was a parachute and said cool. I also don't have an aad, if you do make sure you have the proper paperwork for it and you shouldn't have any problems.
have some fun jumps when you get there. dont sweat the petty things and dont pet the sweaty things
