Two days ago I posted that as part of the merger, status was updating across both programs. As of today, the mileage balances have combined. You should also see your current progress towards elite status.
There may still be some kinks to be worked out but overall the transition should be smooth. According to the email that American sent out today, it seems that the loyalty program combination is now complete. Hopefully there won’t be any major hiccups with the new integrate programs.
