Yes the OP did and that was answered (no one knows yet), but oldgoldflyer's post didn't distinguish EQM's from RDM's, and neither did I when I said it was impossible for me to believe that they'd mess with miles already in people's account (which includes both EQM's and RDM's).
In other words, anyone having an AA and US account can count on the total miles in those accounts being combined. Only EQM's for this year or whatever year they combine accounts are in limbo.
