Sometimes when I fly F9 as a Summit I'll purchase a ClassicPlus ticket for the additional status miles, which used to equal 50% of the miles travelled. On a recent flight using a C+ ticket, I received 75% more miles instead. F9's fare-options chart must contain the answer to my question. Anyone with some insight? I emailed F9 a few days ago, but haven't received a reply
