If you do happen to "forget" to pickup your bag in MIA, AA's left baggage storage area is located on the baggage claim level in the terminal E area (between doors 15-19, IIRC). Saves you time heading directly there if you know your bag is in storage rather than waiting at one of the baggage service desks.
