United MileagePlus has come out with another mystery buy miles bonus promotion. The bonus will be revealed to you after you login and seems to range from 40% to 75%. Personally I received the bottom end – the 40% bonus. Definitely not going to buy miles at that amount. Even if you get 75% it may not be worth it buying the miles as we just saw a 100% bonus earlier this month and there is a high likelihood we’ll see that bonus again in the near future.
Receive a 40% to 75% bonus when you buy MileagePlus Miles. Buy miles here. Until May 29, 20
