Initially, the flights were showing for 25,000 miles, but I think they've corrected that now. Note that the promotion, if you click on the link above, is valid for travel until 31.12.2012, which is great!

Where can this be found on the M&M website? Aah, I see, they're on the special offers home page now. Here, they seem to have different dates according to the destination for the end of the promotion. Bizarre.
