LifeMiles is back with the 2×1 promotion. The good news is that the multiplier is higher now and you get 2.2 miles for 1 mile purchased.
This works out to a little less than 1.5 cent per mile.
Many of the goodies in the LifeMiles award chart are gone unfortunately, but a business class trip from North America to anywhere in South America is pricing out at 80,000 miles RT.
This would cost ~$1,200. This isn’t horrible, but it’s too expensive for me – there are so many other options.
Keep in mind that you can buy up to 150,000 miles per year per account.
