Yup, the bulk luggage x-ray machines will damage film. At our airport they specifically ask you is you have any film in your checked bags. I almost forgot about it and let 4 of those disposable sports cameras get run through.
So definetly leave your film to in your carry on.
I don't see film going away until they can make a cheap underwater digital camera or the digital cameras of good quality become really cheap. And then there will always be the photographers that swear that only film can give them the quality they want.
