Bump - Looks like no concrete solutions here.
Adding my question too.
I've been using Amazon pay ICICI card on IRCTC website directly to book train tickets. I know there is not much benefit at all. But that's been simple for me.
Just exploring if there is any additional benefit on using HDFC Tata Neu infinity card on Smartbuy-IRCTC?
Or do we go with HDFC IRCTC card itself on smartbuy?
