If possible, get a Global Entry Card. That allows you to go directly to the metal detector. Pumps - and CGM's- shouldn'tbe exposed to the imaging technology.I carry copies of the warning pages of my user manual just in case the TSA agent "knows" (or thinks he does) more about my pump than I do. Your pump is likely to set off the metal detector alarm, so have it in an easy to access place, and have your infusion set in a place that is easy to disconnect. I offer to let them hold my pump while I walk through the metal detector again and that seems to do the trick. They may also wand your body, and check your hands and pump for banned substance residue.
As n addedtip,for some people, and I have experienced this, the change in pressure and "G force" during take off and landing can cause some insulin to be"squirted". I disconnect during those times and have no problems. I found out the hard way after a 14 hour flight to Amsterdam and a major hypo.
