Nonrev to CCS

I travel to CCS frequently to visit family, and normally fly confirmed as I always go during peak times like Easter or Carnival... I am considering going standby and am trying to see what is best. I can use AA from MIA to CCS as they have about 4 direct flights daily. I can go DFW to CCS with AA as well or I can look at Delta from ATL. For those that work for DL and AA, what are the loads generally like for CCS? I know CO from IAH are almost always full or oversold... Is there anyone on here who has nonrev'd to CCS or that may have any information for me?

Thanks
