What I have done in the past when taking film thru airport security is to remove all outer packaging (boxs) and then put the canisters in a clear zip lock bag so they can see what it is, you may have to even remove the outer canisters now due to the higher security and then have them pass it around the x-ray machine. I have told them that in the past the machines have ruined my film and they pass it around the machine. But with tighter security this might not fly anymore, Probably best to buy film when you get there.
