British Midland is offering a 50% bonus on puchased miles this week only, through December 11.
bmi miles are especially valuable and leveragable because of their attractive cash and points award chart (though they do add fuel surcharges to awards, cash and points really stretches the points, e.g. one-way business class from the US to Germany is 18,750 miles plus ~ $165 cash co-pay and then of course taxes and fuel surcharges – you could buy the miles for one-way business class cash and points for $268, or $433 cash outlay plus taxes and fees which are not insubstantial).
You can buy up to 24,000 miles per account per year. Since they offer family accounts, though, you can link up to 8 accounts and combine miles as needed for redemptions.
I wouldn’t be bulking up too much on bmi miles though for the long haul, just for awards you’d likely book over the next several months, because British Airways is in the process of acquiring the airline. While we don’t yet know exactly what will become of bmi, the best guess is that they will be folded into BA and bmi destination miles will become Avios.
The normal cost to buy miles is 12 British pounds (~ $19) per 1000 miles plus 15 pound transaction fee per order. Once you get past a couple thousand miles, in order to amortize the transaction fee over more miles, this offer brings down the cost per mile to about 1.4 cents.
You have to be logged in to see the buy miles page, and it’s only when you click through to the Points.com buy miles process before you see the 50% bonus.
