The most recent United Airline points purchase promotion is a Mystery Bonus, up to 100%! For 2 more days, Until November 20th, members can leverage this promotion for a decent value. Reports suggest that accounts have been targeted for 50%, 75% and 100% bonuses. Unfortunately my account only got the 50% bonus.

With 100% bonus, the promotion can be maximized by purchasing 200K United miles for $3500 USD = 1.75 CPM. Unfortunately, with my 50% bonus the promotion is not attractive enough to take advantage. My purchase tiers are as follows;

Buy 5,000 – 9,000 miles | Get 25% bonus
Buy 10,000 – 19,000 miles | Get 35% bonus
Buy 20,000 – 100,000 miles | Get 50% bonus

I will definitely not be purchasing at these rates. However, if your account was targeted with 100% bonus, there are some new sweet spots to consider 🙂
