When I am traveling by air, I carry a brand-new, clean sandwich-sized baggie in my purse or pocket. While I’m standing in line waiting to go through, I detach my pump and put it in the plastic bag, and as I approach the belt to put my purse through, I ask for the pump to be visually inspected. The pump is only off my body for about 5-7 minutes, and so far, every airport I’ve been in has been really nice about it. And, you could always inject an extra unit or so if you’re afraid that short time off would cause you to go high.
