I travel frequently. I had gotten the TSA thing down to a science -- because I have a knee replacement I always opt for the full body scanner if they have it. I typically disconnect and hand off my pump and they swab it. Yesterday was my first time through the Las Vegas airport. They were insistent that the scanner technology had been upgraded and I could now take my pump through it. Granted -- the machine did operate differently than, and looked different from, the ones to which I had become accustomed, but I still refused to let them put the pump through the machine. It was a bit of a battle, but I ultimately won. Does anyone know about a change in full body scanner technology that would allow a pump to go through? I thought it would still void the warranty. But more importantly, would it impair the function of the pump?
