There is noting you can do until at least 3 hours before flight time. This page on aa.com details the "Same-Day Travel Changes Program."


For a $25 fee you can get a same-day standy-by confirmed over the phone, assuming space available. Alternatively you can also ask to go standby on another flight at no cost when you are at the airport.
