for the medication; it's exempt from the 3oz rule. Have it in it's own bag, have perscriptions with you and tell the security agent that you have liquid medications in <insert compartment>. my experiences have usually been just fine. Every bag gets opened though. Once, i could hear them trying to figure out what my vest and compressor were from the xray screen. -That- was funny. "Is it a tv? a monitor? I just don't know. Hey dave... what -is- this ... Looks like an old tv to me.." It was great fun for me. Just be ready for them to ask questions, swipe everything with bomb detection pads and it should all be good. I've flown quite a bit with all my stuff, and have never had a real issue, *knock on wood*. PM me if you have more specific questions or anything about flying and equip. Be well, and good luck!
