For a UA-ticketed (016) revenue flight on AC metal, will I earn Aeroplan miles based on the UA fare class indicated at the time of purchase? For example, will an R class 016 ticket operated by AC earn 100% Aeroplan miles?

I very rarely fly *A but have periodically run into issues with ST codeshare flights booked in an eligible fare class being excluded from earning miles based on the codeshare flight number range, so I wanted to confirm before buying. I don't see any similar restrictions listed on the AC website's partner earnings schedule for UA.

Thanks in advance.
