From now until 20 Dec 2017, purchase Lifemiles and get up to 130% bonus miles. This is of course no way near the recently concluded Lifemiles sale with 150% bonus.
Unlike the previous sale, Lifemiles is employing the usual tiered bonus, meaning the more miles you purchase, the higher your bonus. If you purchase 200000 miles, you will receive a bonus of 260000 miles, bringing your total to 460000 miles, at 1.4 cents per mile.
The maximum number of Lifemiles that you can purchase is 200000 per calendar year, which means that if you have taken advantage of the previous sale(s) and have reached your cap, this sale really doesn’t apply to you.
