I guess on AA's you can use AAdvantage miles to upgrade only on AA flights from most fares unless you want to upgrade on CX but that has to be full Y and J fares only.</font>
(Since that is slightly ambiguous as to whether the "full" refers to J as well) I am under the impression it is "full Y" but any publicly available business class fare (e.g. D on a OWE).
