Wouldn't hurt! One of my former students dad is a dispatcher for AA and he has been walking in a lot of resumes, all have gotten interviews. Try Claudette Carol, she would be a good start. She is the head of pilot recruitment. Chances are they will probable call you for an interview. Also fill out an app off of americaneaglecareers.com and that will get you in the system. With only 4 people showing up at the last ground school they will at least give you an interview if you have the mins. Good Luck! Study the ATP, get some sim time, know 121 rules, and know your jepps and you should be fine.
