Taking a quick look at the American Airlines timetables (in a variety of formats) on AA.com would yield you the most detailed answer you could want.
However, as it didn't occur to check the airline's timetable to see where they go, I'll do it for you:
Boston: 2 x EMB-135, 1 x EMB-140
Dallas: 4 x MD-80, 1 x EMB-140, 2 x EMB-145
New York/LaGuardia: 5 x EMB-135
Chicago/O'Hare: 1 x CRJ-700, 1 x EMB-140, 8 x EMB-145
Raleigh: 2 x EMB-135, 1 x EMB-140
St. Louis: 3 x EMB-140 (operated by Chautauqua)
Edited to add: This is for tomorrow specifically, 12 April.
