Since these planes make up the bulk of the fleet I was wondering if anyone had this statistic.
What engine mfr powers each? Does AA buy RR engines?

They have to be comparable. It's a duopoly, if there was a marked advantage one way or the other, it wouldn't remain so.
They're both about 99.5%. the exact decimal ranges by year ever so slightly.

The people who know will not release such information to the public preferring instead to work on monthly data to even the playing field among competitors

IDK about the numbers but certainly worse than Delta's.
As far as engines,
738's have CFM 56's. 737 MAX are all CFM LEAP.
A319's all the LAA (Sharklet) ones have CFM's, while the LUS ones are a mix of IAE and CFM (Former ones ordered by US Airways were CFM while the former America West ones were IAE)
A320's are a mix of IAE and CFM (Again, former ones ordered by US Airways are CFM while the former America West ones are IAE)
A321's are a mix as well. All LAA ones (Sharklets/transcon) are IAE. LUS differs between earlier A321's that have CFM while later orders have IAE.
While the fleet is all over the place now that old contracts have expired, IAE's are still most often found out of airports like PHX and DFW while CFM's are found out of CLT, PHL, DCA. I also see AA has moved a lot of 738's to CLT while moving a lot of A319 and A320's to DFW.
