When I was there several years ago, the AA GM introduced himself after I checked in and escorted me to a small but comfortable lounge that was near the boarding gate. I assumed this was an AC, but on retrospect may just have been an area they were using to allow Premium Class passengers cool off before boarding the flight northbound. Don't recall whether I was headed to MIA or DFW at the time. Point is it was a dedicated area for Premium Class passengers. No payment was involved.
