Quick question folks- Is there a way to avoid paying the 3.5% markup on Indian credit cards when I spend in USD on the 9W website. I have American cards to pay the amount in USD without the markup, but I also have a Jet Plat Amex to leverage the 12 miles/ INR100. Is there any way I can be billed in INR and not USD for flights from the US to India?

Any suggestions?

cheers,
bp
