BD (before digital) and even recently with a film camera (as back-up to digital), I've put my film canisters in a lead bag, in my carryon - thru at least 9-airport machines in Southeast Asia - no problem. Film developed beautifully.

Otherwise, with digital, not a concern at all.

Good idea, as mentioned above to have various size media 256Kb, 512Kb, even 1Gb - in case camera is stolen. Also a good idea to remove the media if leaving the camera in your room - luggage or safe - when out for dinner.

Memory cards can indeed go bad although I have been lucky. I have used IBM Microdrives exclusively up until about six months ago, and many people don't like the fact that Microdrives (which fit into a CF slot) have moving parts, but mine have never failed me. But I've talked to several people who had memory cards completely fail on them. There's always a chance no matter how you shoot photographs that something will screw up, however - it's just the chance you take! With digital, making a 2nd copy as soon as possible minimizes that risk.

Robespierre, looks like we were posting at the same time about turning up the x-rays to see through the lead bag.

I've had film fog - my photos from Russia in 1987 (wow, that makes me old!)- ALL my negatives are foggy. Granted, their x-ray machines at that time were outdated (to put it mildly), but it can and it does happen. Its wonderful that many have not had problems, but it can happen.

Does it make me sad? Absolutely. Those are pictures I can never get back. I hope that it wasn't a once in a lifetime visit so I have the opportunity to re-shoot.

Also depends on the speed of the film you are using -
