@Saurabhjaiswal you can tell us which bank you are from. 😂
2 things that bug me is rewards redemption fee and minimum transaction value to earn rewards. Also nw matters a lot. Ready to pay little premium for visa/mc over amex/diners.
I also support minimum billing amount to access lounge. Some people abuse that. And because of that genuine users get stiffed. As long as it is in reasonable level, (5-10k monthly,) it's ok.
Cashback over rewards any day.
