I do this when my wife flies with me - Company pays for my ticket, i buy her a saver award in economy with my miles and upgrade her with PP - IMO - One of the best perks for GS.
It USED to be the best perk of GS when you could call and upgrade an entire itinerary but now that its one segment, one direction, its honestly not much value to me. When my spouse and I travel together internationally, we want to have seat assignments together in the same cabin. No way I'm playing upgrade roulette on a long intl trip. So instead of paying the currently exorbitant J prices on UA and gambling on an upgrade clearing one-segment for her, I'm paying cash for two J seats on other airlines instead, getting what I want (including better service) and paying less money.
