don't check anything with any electronics or obvious valuables. Carry on as much as possible. TSA steals everything, super shady. I was at a friend's house and he had all these video game systems, cameras, etc. I was like "what the hell is this?" He said his friend worked for the TSA and his friend gave his wife a gift card that he stole out of a suitcase and she got arrested and put in jail. His friend dumped the rest of the evidence (all the stolen stuff) onto him. This isn't like an isolated person's actions, apparently it's pretty common for them to steal from you, and I've even heard of them taking digital cameras and then putting the memory cards back in the bag, I guess as a favor to the person so they don't lose their photos.
