I am in New Zealand and I am travelling to hong kong, I already have my go ticket and I am buying my return ticket.
When I go to buy my ticket in Qantas (HK -> New Zealand), I found out that I can only buy them in Hong Kong dollar. However I don't have any HKD saving in my NZ account. And yet I can still put my debit card number to buy it.
Does anyone knows how it works? In what exchange rate are they gonna charge me? Will there be a extra transaction fee charged by the airline or bank? (I still haven't hit my buy button)
