Hi, I've been lurking for months and finally found a deal to book. I'm originally from the US and there are laws requiring the complete and total price to be advertised for any plane fare. (ie no hidden fees), you are also allowed to cancel within 24 hours by law at no charge.
You can book a flight (in AUD) through Jetstar using the American website and still use your Australian card. I did it just now. There is no difference in fare. Just no booking fee for any payment method. And the cancellation benefit. Also they don't preselect any baggage/junk offers.
As for address, you could put whatever you wanted to — it doesn't really matter. The billing country just needs to be in the USA. This does not affect CC auth/Paypal. You can still use an Australian phone #.
YES YOU STILL PAY IN AUD.
1) Use skyscanner and in top right change currency and country to USD/USA.
2) Find your jetstar flight — you need to click book with: jetstar. Not with any of the other companies listed.
