I understand I could split the PNR and cancel only my award flight and get the points back. However, since the confirmed eUp was done from my account, would my partner's confirmed upgrade disappear once her PNR was split from mine? I don't want to risk it unless somebody has done exactly this and is sure it would be fine.
