Need Help with "snakes on a plane"!

[4theSNAKElady]

Ok. So I knew the data that I needed would be found nowhere else but from you fine folks! Here's the situation: a friend of mine is visiting from LA, and she wants to take home one of my baby cornsnakes. I printed her a caresheet, even shopped for her plastic shoebox, and gave her a book. I have also provided her with a very small sterilite box "travel container" (it's about 4"x6") thinking, she'll just be slipping it in her carry-on bag for on the plane. She wants to take it right home with her, and the plane may be making a stop along the way. I wouldn't think it will be a problem, but she did pose some very good questions, that i did not think about, considering the security on planes now. First of all, would she be allowed to do this? Second, if so, is the x-ray machine gonna harm the snake? or is there an alternative "security check" for it? It's just a wee baby corn, probably indigenous to the whole country. If anybody has had this situation, or knows how it's handled, please let me know! It's for my friend, and she's so excited about having this little snake! In my opinion, it shouldn't be a problem transporting him on the plane in a tiny plastic box, as long as its tightly secured. But you never know...why I'm asking.......
