So over the last several months i have probably signed up for half dozen dining for miles programs. I have never used them because most of the restaurants near me that i like dont participate and the ones that do participate are not worth going to. Hence, I never pay attention to these accounts much and i have no clue which CC i enrolled in them. But next week I may go to a dining for miles restaurant...i am curious to know what happens if i use a CC that is enrolled in several of the restaurant programs (like my chase sapphire is, probably). Which dining program will yield the miles? also, which dining miles program do you think has the best benfits and bonus?
