Did she end up getting upgraded?
Sometime if there was space in business she was upgraded, but i was not in charge of passenger and cabin sitting issues. I was a commercial cargo agent-manager for various e. and w. coast US stations, and only dealt with excess weight, units allowed, and over sized luggage.
I am not a monster, SU/Aeroflot any given station managers are not monsters... if a flight was fairly empty she could load her extra luggage at no charge, but so were allowed mothers with kids, families, etc. But with a fairly full flight she had to pay like all others. after all.. there is an indirectly relevant matter of "Center of Gravity positioning " in luggage and cargo loading process, and at some point there are costs involved that relate to weight the aircraft is carrying, and work required to load/off-load... it's not free to the airline itself..
People like to help when they can, it's TAT's sense of entitlement that's unacceptable. MIA and JFK station managers still "remember her" with a few choice words...
I am talking 90's, and not only "big wig" TAT was on those flights to Russia...... but also presidents and chairmans of major corporations and MOST importantly their top researchers, scientists, and developers (Exxon, Mobil, Boeing, Airbus, Coca-Cola, Pizza Hut, etc).
These guys all bought 1st/business class with perks, but when something went wrong, they had no issues flying passenger. They never even raised an issue of not paying for excess baggage.... even when they were carrying equipment and supplies that would Directly (!!!!) benefit Russia...
And here is a skating coach claiming all these free perks and bossing people around...as if she prevented WWIII...
