I recently experienced the same that fungirl mentioned above. I am 2 years into the Family Plan since my wife and 4 kids travel with me every summer to Russia for a few months. Their miles all posted a few days ago to my account at the 70% rate for each instead of just for my wife and then 40% for the rest. Very nice.

I also am able to add/take away additional family members with a simple email to Aeroflot Bonus as sometimes my mother, my mother in law or my father in law travel with us. Actually, I've added non family members as the 7th person a few times just for one flight they were taking with me and noted as much in my email to Bonus to have them added. No problem at all.

EQM status is only for me though. None of their miles have ever posted to my as EQMs. All in all the program works for me/us just fine. I get more miles quickly which I use exclusively for the purpose of upgrading Q fare tickets to Business Class.
