Summing up

United MileagePlus buy miles promotions can be a great way to accumulate miles for cheap Star Alliance redemptions.

However it only makes sense to do so when the offer is at least above-average and you have a particular Star Alliance partner redemption in mind.

The other program that you should consider buying points through for travel on Star Alliance is Avianca’s LifeMiles.

And as always, make sure there is award availability for the redemption you are eyeing off.
