Hello I have 2 GPU available for United Airlines. I think these can also be used with Lufthansa. I will not be able to use it so if you are interested, let me know and we can work out an arrangement. For reference, GPU allows upgrade on flights from Continental US to all International locations. This can potentially save your $$$$. I also have 4 Regional Premier Upgrades available which can be used for upgrade within Continental US, Central American or Hawaii.
