The latest sale offers a bonus of up to 75% and the deal is in place until October 31. In order to get the 75% bonus, you need to buy at least 30,000 miles. Buying 30,000 miles will get you a bonus of 22,500 miles for a total of 52,500 miles and will cost about $1100 including taxes. That amounts to 2.09 cents per mile (CPM), which makes for an attractive proposition, especially if you are short a handful of miles for premium award travel redemptions.
If you buy between 5,000 and 14,000 miles, you’ll get a bonus of 25%, if you buy between 15,000 and 29,000 miles you’ll get a 50% bonus. You can buy a maximum of 85,000 miles which will give you a bonus of 63,750 miles for a total of 148,750 miles.
From my observations lately, it’s been a bit easier to find Lufthansa First and Business Class inventory and even Austrian and SWISS Business class awards. This may actually be a good time to take advantage of a deal like this.
