I've probably missed something simple, but with the discussions regarding the best country to purchase or ticket a DONE4 (for example), must the journey start in the country the fare is purchased in?
I was reading the OneWorld product information and saw:
"When travel originates in a country for which a specific local currency fares is published and the
ticket is sold in another country, the fare will be that published for the country of origin converted to
the currency of the country of sale at the bank selling rate. The resultant fare must not be lower
than from the country of sale.
Exception: Not applicable for sales made and/or travel originating in Canada"
IE: If I am in Australia, can I purchase a DONE4 starting in SYD from AA at the current exchange rate, or do they have to match the QF price according to the above rule? Would it be different if I started the journey in the country of purchase (in this example the USA) with a separate "positioning" flight?
