The opportunity cost doesn't always make this viable from my perspective. With that said, there is still the opportunity to buy Lifemiles during bonuses for *A awards via Arrival & reimburse that way. Pretty much the only one I'd consider buying miles with, as I'd rather INK miles if my intention was to translate CB -> miles
