Well don't I feel stupid!
I noticed on the AA reward redemption chart that mileage upgrades are available "From Most Economy/
Business Class Fares" and assumed this was similar to Delta's "from selected fares." In the case of DL, as you may know, almost all of the cheap fares (L,U,T class) are excluded for mileage upgrades.
Wow, if any fare can be upgraded on AA, that is a significant difference between the two airlines. I'm going to switch to AA from now on, whenever possible. Between that and MRTC for those times when I don't upgrade, AA is sounding better and better.
Thanks for letting me know about this!
