First, let me be clear. Nothing in this post is intended to be a shot at the OP. I join him in celebrating his success.
But, don't we hear here, not infrequently, that when the UG system works consistent with DL's rules, and UGs are awarded at the windows, that this is unfair to others who pay higher prices nearer to departure, but find no UGs left available?
If you accept this premise, would not the sale of FCM UGs for a pittance over the price of coach also be unfair to those who, purchasing closer to departure, might be willing to FCM for a higher incremental cost?
