Here's a tip when carrying your camera on a trip. Put all undeveloped film and cameras with film in your carry-on baggage. Checked baggage screening equipment will damage undeveloped film. If you've gone digital, you'll be OK at the x-rays.
No matter what type of camera you have, if you've invested in a fancy schmancy removable lens, and you are pulled aside for additional screening by TSA, ask them kindly to be careful regarding your lens. I have seen more than one expensive piece of equipment fall onto the hard floor at the airport screening area. Ouch! That's gotta hurt!
