Not getting clear answers from UA leads me to think worst case scenario.
I have PMed UAInsider and was told to "...be conservative..." My question was if I get a pre 2/1 C award, and F seats open up will the ticket be grandfathered and I will owe the old difference or will I be on the hook for another 40,000 miles if I make any changes.
