American Airlines Information Gathering

matt-fu writes "Cory Doctorow posted a story on boingboing.net this morning describing a recent hassle while flying American Airlines. It seems that since he was traveling from the UK to the US with a Canadian passport, he was actually asked to give out the names and addresses of everyone he would be staying with in the US! He has written an open letter to AA in response. Has anyone else had something like this happen to them?"
