From now until 18 Nov 2017, you will receive a 140% bonus when you purchase Lifemiles.
The maximum number of Lifemiles that you can purchase per calendar year is 200000. This means that you will receive a total of 480000 Lifemiles when you purchase 200000 Lifemiles during this promotion period.
This promotion is by far the best we’ve seen in the recent months. Last year, similar bonuses were offered in both Nov and Dec, so keep your eyes peeled for another potential sale before the end of the year.
