I had no issues with Hawaiian airports or the smaller ones in So Cal. But when I went to LAX, I literally was told I had to pick the full body scanner or an x-ray. When I questioned the full body scanner I was told that was what everyone picked when they wore devices and it was one or the other. When I asked again can't you just be manually checked as I had before, (a few years before this) I was then told I would have to go to another terminal to check in differently. I know someone that calls the day before to let them know and they direct her to a specific area. And going through the full body scanner I was still wanded and checked for residues.
At the time I didn't really think about it as I had just fractured my back a few weeks earlier and in a wheelchair for the airport, so I wasn't feeling the greatest and I don't think I wanted to care too much??? Later I did learn it's not recommended but it did function completely okay. The Insulet Omnipod people when I first called them a couple of years ago I thought they said an x-ray was okay for the pod, but then the next time I called they said no. But mine has been through an x-ray a couple of times and been okay. (the pods themself only) But I believe there is the chance it might not be.
I was ready to kick and scream the next time, but it wasn't LAX and I didn't have an issue at any other airports. I also took all my "supplies" with me on the plane. Too important to have any of it in my luggage and possibly lost.
