I have just purchased my first ever Dividend Miles today. 1478USD for 100K miles. I have held back from buying on my wife's account as we are still not sure if we are travelling to Europe yet, and I do have 75K miles on BMI account (enough for J M+C Award).
Ironically, even though I started this thread, it actually took me this long to make a purchase, partly because I need to burn other miles that I have already in my account.
The AUD is taking a battering the last few days. Now it is 1 AUD:1 USD. I suggest you jump on the opportunity now than later! In fact, I was so rushed, I ended up using my Amex Plat Edge CC to make purchase, when I have my 28 degrees MasterCard sitting in my wallet and save myself international transaction fees! Doh!
