zakami,

I did fare checking and the best you're going to get from there to S. Florida, at least this particular weekend, is $500-600 on AA. DL had a few cheaper, but I imagine you want to stay with AA for miles and upgrading.

I don't know if it's because of Memorial Day weekend. But, per my previous posts, you can get much better deals $200-300 range other times so keep looking.
