I am kind of spending most of spends in DCB and getting the base return of 3.33 and using smartbuy to get 6.6 to 9.9% returns. I am using the rewards to book domestic flights mostly with 70% utilisation of rewards as vistara doesn't have the network in the places where I am flying most of the times. But I was using magnus previously to get Accor points for hotel stays. I have to close my magnus card by October else I have to pay annual fee(which I will not do). I am kind of spending around 12 lakhs in DCB. I am confused on should I go for atlas because DCB conversation to accor is 2:1, which is less compared to conversion rate towards flights which I am using. I wanted some suggestions here
