It really is sad if indeed those seats up front did go empty. I know its a yield managment game but if they could not get any revenue why not go for the good will game and upgrade? I know UA does sell upgrades at the gate, and that has its own issues, but they would not let seats go empty in the front IMHO.
I'm hoping my upgrade from EWR-LGW in June clears. My May ones cleared no problem and the return in June cleared no problem but outbound still has not.
Cheers
