Hi April @alr010,
You should not have any problems with airport security (TSA) issues when traveling with an insulin pump as long as you are “open” and don’t try to conceal - at least I haven’t. As far as an insulin pump being adversely affected, I haven’t encountered problems and I’ve been through all types of scanners; I don’t use CGM so I can’t speak to that but I suppose that the receiver will travel through security the same as a mobile phone.
This link https://www.tsa.gov/travel/special-procedures is to the TSA regulations; the regs speak to “disabilities” so you may need to point out to certain TSA agents that Type One Diabetes was the only disease specifically identified as total disability in Public Law 101-336 - The Americans with Disabilities law. Regretfully I once had to have an agent who insisted that I remove my pump taken off-line and sent for additional training. Other than that one instance I had only one delay when an agent asked if I could step aside and talk; her husband was considering starting on a pump and she had lots of questions.
