Presumably not coincidentally, is an exception on AAdvantage as well-- -any- QF #'d flight earns AAdv credit as if a QF prime flight, doesn't need to be operated by a OW carrier nor listed affiliate.
For AAdv, JL is a similar exception (any codeshare operator counts.) I -think- AY as well, haven't checked on that one in a long time.
