If the elite and the other individual are on the same PNR and the elite uses their miles to request the upgrade for both then the 2nd traveler with inherit the elites status priority.
All very interesting and useful, thank you.
I ended up abandoning the MUA and going for the buy up. It did not look promising. SFO/LHR the last week is 90% booked in business and premium economy, while economy is largely empty with many passengers having entire rows to themselves
