What happens to my United Airlines Miles when a refund is processed?

When you make an eligible transaction, your United Airlines Miles will be classed as "Pending" for up to 23 days. This is to account for any refunds that may occur in that time and ensures that the correct amount of United Airlines Miles will be applied.

If you receive a refund after this period, we will remove the equivalent United Airlines Miles earned from that transaction from your balance.

If the value of the removed United Airlines Miles exceeds your current balance, your balance will go into a negative position and any future earned United Airlines Miles will work towards bringing your balance into a positive position.
