After getting shafted on AA earning for a RTW ticket, I spent over an hour on the phone with AA Customer Service about earning EQD on complex tickets. They informed me that there is now a calculator they have access to that will give the earning for each segment prior to flying, but you would have to call AA CS to get that answer. There is of course the projected earning on AA.com prior to purchasing, but it doesn't work if there is any non-AA coded segments.
