Apologies, but I just want to be doubly sure of my options re: Status Exceptions.

I took a status match challenge last year and hit platinum, which will be expiring this month. Living in NY I did all my flying on Delta and hit DM for 2018. Now it looks like we will be moving to Miami in April this year -- would I be able to do any sort of matching/challenging to AA as it would be a much more useful program to have status on over there? Many thanks
