I usually ask for a hand inspection before walking through the metal detector. I was told by one security person that film should not be carried through these. I usually have less the ten rolls and they will swab a couple and give the rest back and I'm off to my gate. However, thanks now to the Xmas terrorist there's no telling what one may expect. I'm taking a trip soon that will require me to bring 75-100 rolls of Arista Premium. I'm thinking to avoid any hassles sending them ahead to my destination. However, doesn't FedEx and UPS routinely x-ray packages? If they do, then maybe it's better to take ones chances with carry on through the airport.
