What is the forex markup fee on Indian credit cards?

Forex markup comparison: Amex = 3.5%, HDFC Infinia/Diners Black = 2.0%, Axis Atlas = 3.5% but with milestone fee waivers, ICICI Emeralde = 3.5%, Standard Chartered = 3.5%. If you travel more than twice a year, the math favours Infinia or Diners Black.

I've been using this card for over a year now. In my experience, the rewards are decent but the real value is in the lounge access and the milestone benefits. Make sure to read the fine print on the welcome benefit — most banks only credit it after the first transaction, not on approval.
