I would check to see if the space is also showing on QF and/or BA. QF has been my go to. I can't speak to the reliability of booking what AA shows with MP. The tips & tricks of booking CX premium cabins, Pre COVID-19 and Pre announcement of joining oneworld may no longer hold true in the current environment.
