As usual the bonuses on offer vary depending on how many miles you buy (the more you buy the bigger the bonus) but, on this occasion, the banding is quite generous so you don't have to buy all that many miles to get the full 100 % bonus. (travelingformiles.com)
As usual the bonus miles will post 6 to 8 weeks after the promotion ends so don't expect to see the extra miles until February 2016. (mytraveltools.com)
