Had a problem before like that. We didn't get out of San Juan to Aruba until 9:30 at night when I should have been in Aruba at 1 PM. WE WERE LESS THAN THRILLED!!!!!!!!!!! However, after complaining to American afterwards, they made up for it with a voucher. Would rather the day in Aruba that was lost due to their messing up. hold your breath, it's beyond your control. I will say american is changing a lot of flights and seems to be losing control and their once great reputation. Wouldn't surprise me to see them go bankrupt within the year.
