Looking for input/help.

Currently returning from Europe in June BCN-MIA-DFW-SAT in Business. Arrive in Miami at 335PM (on 6/21) and depart 700PM. With all the observed delays in Customs, is that realistically enough time?

Or, should I try to change to BCN-LHR-DFW-SAT (arriving DFW at 655PM and departing at 840PM)? There was a schedule change, so I may have an opportunity to switch.

I'm new to AA and haven't been to MIA or DFW in many years, so any insight appreciated.
