Shawn, like the others have said, it doesn't have to be a huge issue. They definitely will pick up on the fact that there's something 'foreign' on your body, though. When I fly, I try to make sure that my pump is on me somewhere easily accessible. As I'm stepping into the full-body scanner, I tell the person working there that I have an insulin pump on my abdomen (or arm, whatever). That gives them a heads up. Then, when you get out of the scanner, they will want to test for any explosive residue. So they will have you touch your pod with both hands and then will swab your hands and then do a quick test of that swab for any residue. It's quick and not too intrusive. But the fact that they want you to touch your pod is why I suggest trying to have your pod in an easily accessible spot. If it were on my thigh I'd have to pull down my pants and would want a private room for that. If it were on my arm and I had short sleeves on, I could just do it there quickly in the middle of the security area without much fuss. As a female, it worked to have an untucked shirt and I could touch the pod easily with both hands on my abdomen. Hope that gives you a better picture of what happens!
