Over the past few weeks, United has been selling miles for their Mileage Plus program which has been giving buyers the opportunity to receive a 100% bonus on the miles they purchase.    This sale ends on August 15, so there are still a few days left to top up your mileage balances so you can redeem for those Lufthansa First Class tickets that have been relatively easy to find.

From what I gather, there may be one catch in order to be eligible for the offer and that is you need to be a United MileagePlus credit card holder.  However I don’t know how tightly that will be enforced.  Once you go to the Mileage Purchase page and log in, you’ll see if you are eligible for the bonus mile offer.

The sale is structured so that the more miles that are purchased, the higher bonus.   It’s broken down as follows:

    Buying between 5,000 and 14,000 miles will earn a 25% bonus.

    Buying between 15,000 and 29,000 miles will earn a 60% bonus.

    Buying between 30,000 and 75,000 miles will earn a 100% bonus.

Mileage Plus members can buy up to 150,000 miles annually for their account, including the bonus miles that are awarded at purchase.

Additionally, anyone who purchases miles during this promo will be entered into a drawing that will award winners additional miles.   1st Place will get 250,000 miles, 2nd Place will get 10000 miles, and 3 3rd Place winners will get 50,000 miles each.
