It also isnt as simple and quick as PTY where you get off the plane and then hop right back on at the same gate. If you have your boarding pass for the next flight, you have to follow the signs for "international passenger transit."
I guess I missed that part. Banking on everything being on time coming in from Miami is risky at best. He can still stay air side and avoid customs and immigration, but there is the risk of missing the outbound flight. If it's part of his single RT ticket, then AA should be responsible with dealing with any delays that they may cause. Worst case scenario would probably be the morning flight out the next day.
