I needed to extend our FF miles, which were set to expire at the end of February. We are in the US, so I wanted a quick and easy method that could be accomplished online with a US credit card. On January 10, I logged into our Qantas accounts and in each account, purchased a $25 gift card from Qantas Box Office. Shipping was free. The 50 miles posted to each account on February 11, so pretty much exactly a month later. This extends our miles for another 18 months at a cost of $25 per account, and leaves us with gift cards that can be used toward purchase of an event in Oz next time we head Down Under. Anyone know if there is a better/cheaper way for a US resident to accomplish this?
