My wife, child and booked using CO miles on an AF flight from BOS-JNB in O (Business award) on Sept 2nd . When we booked it, we were not told that two of the legs (both BOS-CDG) were in economy (no O inventory). Anyway, we elected to continue with the tickets. After we checked the e-tickets, I called International reservations, and we were told that we should check back periodically. As yet, no inventory has freed up. I have several questions that I would appreciate help with:

1. How likely is it that O inventory will open up in the next 7 weeks? C is currently ½ full.
2. We have “paid” -using miles- for business class tickets, even though we are seated in economy for 2 of the 4 legs. Is there likely to be a note on the booking record to this effect?
3. Regardless of the answer to 2 above, are we likely to be given some priority if Business class seats are available?

Thanks in advance for your help.
