United Airlines Buy Miles 100% Bonus Through October 11, 2022


United Airlines has launched a new sale to buy MileagePlus miles at up to a 100% bonus until October 11, 2022.

United Airlines has monthly promotions for buying miles, but they all max out at a 100% bonus or a 50% discount. In addition, the airline occasionally increases the miles you can buy in a calendar year from 175,000 to 250,000.

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

Price at 100% bonus:

The cost of a mile under this offer is 1.88 cents each.

Does it make sense to purchase the United miles?

The answer is likely yes if you use them for international business or first-class tickets between expensive city pairs.

United has stopped publishing award charts but recently launched a website that featured award deals (read more here), and Star Alliance charts are now gone (read more here). In addition, many awards have become way overpriced in the number of MileagePlus miles required (read more here).


It can make sense to buy miles if you redeem them for an international premium cabin award. You can always redeposit the miles (with or without a fee) if travel restrictions, bans, or last-minute other changes exist.

You should not buy miles unless you have either 50% off or a 100% bonus offer.
