Below are the rules o Expedia...I might not take the chances with that one!
--------------------------------------------------------------------------------
Credit cards with billing addresses outside the USA may only be used to purchase the following on Expedia.com:
hotel reservations
rental car reservations
activities
When entering an international billing address, be sure to click the "Non USA billing address" radio button to enable the correct address format. Note: All purchases containing a flight or cruise must be made using a credit card with a domestic billing address. At this time, you will not be able to book flights with your non USA credit card.
