I haven't travelled in more than a year, so I'm not up to date, but if I had two 2Gig cards I wouldn't let them anywhere near any scanning device. Too big an investment to lose to some dumb machine which isn't even looking for them anyway.

X-ray machines won't hurt the CF cards, but the magnetic scanners that you walk through will. Just be sure you send your cards through the x-ray and don't carry them in your pockets. It's much easier to get digital "film" through airports than to try to pass normal film around the x-ray machines or worry about fogging as it goes through. U.S. airports have to hand check film if you request it, but foreign ones don't and most of the ones I've been through lately refuse to hand check.
