EDITED Nov 12
I’ve flown to and from Toronto with my Ping, and it has set off every metal detector everywhere (Halifax, Toronto, Newark) even though I take the belt clip off.
EDIT: On my most recent flights (Nov. 5 & 8), I removed my belt clip and did NOT set off the metal detector. In Halifax, the screener saw my pump before I walked through. I told him it was an “insulin pump for diabetes” and he said, “Okay, no problem,” and that was that. In Toronto, no one saw the pump (in my pocket) and the metal detector did not go off. So the people who say to remove the belt clip and expect no problems are right
In Toronto, they asked to swab the pump for explosives residue and were very nice about it. They did not want to touch the pump; the security person asked me to hold it while she swabbed it.
In Newark, I got taken aside for a pat-down and they swabbed my Ping. They were nice, too, mostly out of fear of offending me, I think. I carry a letter in my glucometer case saying I am diabetic and need needles, insulin, etc., but no one’s ever asked to see it.

From now on, pat-downs in the U.S. will be conducted using the fronts of the hand (palm-side) instead of the backs of the hands.
Another piece of advice: I downloaded the user manual in PDF and I keep a copy of it on a thumb drive in my diabetes kit. That way, I have all my instructions with me in case anything goes wrong, but I don’t have to carry a heavy book around.
