aa.com will not allow you to ticket the same passenger twice on the same flight. You can use two browsers to cancel the old hold just seconds before placing the new one. Or, you can book the new one without your FF number and go back and add it after cancelling the old one.
Keep in mind that the hold is valid for the remainder of the current day and all of the next day so if you make the hold one minute after midnight in the departure city you get nearly 48 hours. Just be careful with time zones.
