Update on this American Airlines fiasco! Not only has American changed the SJU-AUA segment to a prop plane, but today they have now changed the schedule! We now end up with a
6-hour layover in SJU on the way down, arriving AUA at 8:49 pm! Our return flight is even worse!! Our departure time has been changed to
7:30 am (!!!) leaving us a
9-1/2 hour layover 
in SJU!!! I SO wish we drove the extra couple of hours to get a non-stop out of Boston!
Has anyone had a situation like this and the airline accommodated a change in flights without a penalty???
