United Airlines MileagePlus Buy Miles (Up To 100%?) Mystery Bonus Through November 20, 2017

United Airlines has launched Mystery Bonus offer for buying MileagePlus miles at perhaps up to 100% bonus for purchases made through November 20, 2017.

United Airlines MileagePlus Mystery Bonus November 2017

United Airlines has promotions pretty much every month for buying miles, but they all max out at a 100% bonus or a 50% discount (exactly the same offer because United usually limits the number of miles one can purchase per year including any possible bonuses to 150K).

You can access this offer and check your bonus percentage on United’s website here.

The price of a mile at the 75% bonus when buying the maximum amount is 2.15 cents each.

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 still likely yes.

United Airlines made some changes to the MileagePlus awards effective November 1, 2017. You can read more about these recent developments here.
