United Airlines MileagePlus Buy Miles 85% Bonus Sale Through December 31, 2019

United Airlines has launched its last MileagePlus buy miles sale for 2019  that is valid for purchases made through December 31, 2019. You can check your bonus or discount offer on United’s website here.

United Airlines has promotions every month for buying miles, but they all max out at a 100% bonus or a 50% discount (the same offer because United usually limits the number of miles one can purchase per year, including any possible bonuses to 175K).

You can access and see your bonus on United’s website here.

Here’s the bonus schedule:

Price at 85% bonus:

The cost of a mile under this offer is 2.03.

Does it make sense to purchase United miles?

If you use them for international business or first-class tickets between expensive city pairs, then the answer is likely yes. United stopped publishing award charts earlier this year but recently launched a website that featured award deals (read more here).


There could be an issue with the bonus correctly displaying if you try to make the purchase. I received the offer for 85%, but when I go to complete the purchase, there is none.
