They are instruments used to support upgrades from one ticketed cabin to a higher one on United and Lufthansa (the latter with restrictions) flights.

No, but there is a minimum fare class that is required and the difference in cost between the lowest bookable fare and the minimum GPU-allowed fare class could be considered the co-pay. However, there is no co-pay fee for using a GPU.

If there is confirmable space at the time of booking, a GPU-supported upgrade is supposed to clear. Otherwise, it will go to the upgrade waitlist.
