i've noticed that the rates in EUR, USD were both 'competitive'. also, i like the new statement format where they showed the calculation for each transaction separately.
The rates vary drastically for Visa and Amex variants for Jet ICICI cards. For instance, the INR/ HKD rate I got on Amex and Visa is 6.98 and 7.26 resp., for transactions on the same date (6.93 was the interbank rate, as quoted at oanda.com).
