If yes, there are at least 9 vacant seats available for sale. If not, try, 8, then 7...... etc.
If the flight is outside of 48~72 hours, there are bid upgrades that AC would want to consider. Once check-in opens, there're also LMU for purchase. AC may have incentives to leave all free eUpgrade for lower tier members until the gate. My sense is that those willing to pay to upgrade would always be preferred over "free" upgrade particularly lower tier members.
