I haven't peeked at the manifest since int'l flights in the PMUA days, but back then it showed customer elite status and the meal priority order. So I guess an FA could deduce full fare or upgrade/reward, but only if there is a meal order priority discrepancy between a certain elite status and full fare. For example, full fare and 1K are always ***, so it's not possible to tell for 1Ks.
I don't know how the manifest was shown PMCO or how it is post-merger.
