Same here, altough I still have some time left to figure this one out.
Could you share the double miles promo from EY? I'm afraid I have missed this.
Furthermore, I tend to write or call AA because I don't think that it was intentional to exclude EY Z-fares from any earnings.
I can fully understand that they don't want to grant bonus miles for Z vs bonus miles for I or J, but it's not very logical that one would earn 0 miles for Z, which is still more expensive than a regular ticket in coach (or even discounted tickets in coach). For the latter one still would earn 100% of the miles flown.
