Look at the co.com version of partner earning (sorry...on BB now so cannot get the link easily; OnePass, Earn, Partners). You get 50% EQMs on L fares unless booked at copaair.com. CO got rid of that rule for their own metal but it still exists for Copa apparently.
You also only get 100% RDMs as a platinum (versus 200% booked online) I believe.
And I agree that just about anything is better than a 6 hour layover in MIA. Actually connecting in PTY is really nice. It is a very easy terminal.
