Over the years the pumps have become more sensitive to X-rays as the electronics in them have shrunk by orders of magnitude and are using much lower voltages. These days it would be unwise to expose either a pump or a CGM to X-rays or to the scanner at the airport especially since we are advised to not do so by the manufacturer. Not everyone is like Medtronic, if you misuse the device they may refuse to replace it.
I travel often and just started the CGM a month ago. I’ve had no problem handing my CGM to TSA in a bag with the page from the user manual that says “don’t X-ray or scan” and they just check that my Dexcom receiver is not a bomb (Duh). When I’ve been asked to go through the AIS I simply say “I am wearing a medical device and going through the scanner could END VERY BADLY.” I just leave it at that and I get the pat down. As someone with diabetes, the best thing I ever did for travel was get Global Entry which comes with Pre-check which assures me at most major US airports I have expedited security and only metal detectors.
