I just checked out the "Irma" section on the AA website, and there is a link you can click that takes you to a page where you can enter your ticket number, and they will let you know if you can cancel with a refund or not.
They have some very ambiguous instructions on an automated refund process. They say you must first cancel your flight to initiate the refund process, but why would you do that unless you have confirmed it's refundable? It also says that if your fare is refundable, there should be a cancel flight/change flight link on your "my flights" toolbar. Again, not very clear and not worth losing your $...I'm waiting until better info is available. My flight is in December.
