Quick question folks, I recently used a GPU to try to upgrade a flight from SFO to FRA with a connection in ORD. Obviously, I am only interested in upgrading ORD-FRA. As it turns out, I am flying in 2 days and my SFO-ORD leg upgraded but the ORD-FRA did not. If I end up not getting the ORD-FRA upgraded, do I get my GPU back or is it lost?
