AA - Using AsiaMiles:
-AA flights in fare classes Y, B, and H are eligible for Economy to Business Class Upgrade Awards.
-AA flights in fare classes J, D, and I are eligible for Business Class to First Class Upgrade Awards.
BA - Using AsiaMiles:
-BA flights in fare classes Y, B, and H are eligible for Economy to Premium Economy Class Upgrade Awards.
-BA flights in fare classes W, T, and E are eligible for Premium Economy to Business Class Upgrade Awards.
-BA flights in fare classes J, C, D, I, and R are eligible for Business Class to First Class Upgrade Awards.
-Upgrade Award is not applicable for Economy to Business Class upgrade.
CX - Using AsiaMiles:
-CX & KA flights in fare classes Y, B, H, and K are eligible for Economy to Business Class Upgrade Awards up to 10 days prior to departure.
-CX & KA flights in fare classes J, C, D, and I are eligible for Business Class to First Class Upgrade Awards up to 10 days prior to departure.
there's nothing in that list to do with codeshares. you can upgrade any AA own-metal trip using AsiaMiles (round-trips only, no one-way redemptions), provided the correct booking code has been used and the correct upgrade inventory is available.
if you want to compile a list of award redemptions on AA using other programs, that's one thing. it's not AAdvantage miles, of course, but it does hinge on AAdvantage award inventory availability...
if you want to list all the ways redemptions on all oneworld partners can happen, that's awfully complex and not very American-specific.
