What is the Miles Booster feature and how does it work?

Miles Booster allows you to supercharge your United Airlines Miles balance by rounding up your transactions to the nearest 10p or 20p, and thereby earning miles at a rate of 1 mile / GBP £0.02. You can choose your roundup amount or turn it off.

You can switch Miles Booster on or off at any time.

Miles Booster uses the GBP value of each eligible transaction. Refunded or reversed transactions are excluded.

United Airlines Miles earned with Miles Booster will be pending for up to 23 days, as per our standard United Airlines Miles crediting policy.
