United has launched their latest Mileage Plus sale offering up to a 100% bonus when you purchase between 50,000 and 75,000 miles.

The tiers for this sale are as follows:

Buy between 5,000 and 19,000 miles and get 25% more miles.

Buy between 20,000 and 29,000 miles and get 50% more miles.

Buy between 30,000 and 49,000 miles and get 75% more miles.

Buy between 50,000 and 75,000 miles and get 100% more miles.

For this promo, buying 75,000 miles will cost $2625 and you’ll get another 75,000 miles which means you’ll wind up paying only 1.75 cents per mile which is about as good a deal as you’ll ever find.    Taxes may take the CPM up a bit, but it is still among the best deals that United has offered in a long time.

You can buy up 150,000 miles a year per account.  Bonus miles count towards the 150k maximum.

As far as the contest is concerned, if you buy miles, you’ll be entered into a drawing that will award 5 prizes.   The Grand Prize is 250k miles.   Second place gets 100k miles, and 3 other winners will each win 50,000 miles.  Obviously the miles won from the contest will not count against the 150k maximum miles that can be purchased for an account.

No Purchase is necessary to enter the contest. Directions for entering the contest are included in the Official Rules.
