rhondak, what dates are you flying in October? You might want to take a look at Southwest. They are offering $50 one-way internet specials right now. If you get that they are "unavailable" try adjusting the date by a day if you're at all flexible. As I said before, I saved $600 by flying Thursday/Saturday rather than Friday/Sunday.
I just tried to search AA again, but I get a system error right now.
