I have never used any of my Business Extra points on AA. I have some questions on them...

I have an itinerary next month that I just booked. When I go to the AA Business Extra website to try and book upgrades I get "only available for waitlist request". If I even both to book this, am I likely to get the upgrades? Do they get pulled before regular free domestic or 500-mile domestic upgrades are available? There are 9 FC seats available on each of the two flights. The first flight has the waitlist option and the second flight says "not eligible for upgrade".

Or is it just a waste of my time and I have no chance of them going through? And I should only bother if they are able to be booked instantly after I book the itinerary? Can you find out before booking an itinerary if instant Business Extra upgrades are available on the flights you want?

Thanks for any help.
