For all of you who thinks that the CA "owns" the jumpseat I would recommend reading the People Manual 7-47. Pretty in depth chapter about jumpseat priority and an offline jumpseater is below a pilot commuting, regardless of who they happen to be married to. Also a little section about when and why a CA can remove a jumpseater, and it's not for their spouse to have a seat. I would say the People Manual makes it pretty clear that FedEx owns the jumpseat and there are clear policies regarding it's use.
