I'm planning to travel to Canberra, Australia in July this year. I have 100,000+ Avios miles and would like to use them to help with the costs of the otherwise expensive flights. Does anyone have any advice how best I should do this? Should I go through London on BA? Or use a One World Partner from DC? Will my miles get me as far on a partner? My strong preference would be to use BA, but the most important thing is... I get there!
