Merge MileagePlus Accounts

If you have more than one MileagePlus account, start here to submit a request to merge them. By having just one account, all your earning will be in one place, which means you'll get to an award faster. We'll combine your Premier qualifying activity, lifetime miles balance and account history.

Steps to request your accounts to be merged:

  1. Log in to each of your MileagePlus accounts.

    You can log in with your account number, your username or your primary email address. Complete the log in with either your password or your PIN.

    Please note: The first and last name must match between the accounts. If you have to update the name on an account, visit the "Names changes" page on united.com to learn what is required.

  2. Select the account number you prefer to keep.

    Please note: If one of your accounts has Premier status, the system will automatically choose that account number and won't present you with a selection. This is to ensure that your Premier benefits continue uninterrupted.

  3. Submit your merge request.

    Your active MileagePlus account number will display on a confirmation page. We will also send a confirmation email to the address listed on each account.

Please allow up to seven days for the account merge to be completed.

If you have more than two accounts to be merged, you will have to complete this process multiple times. As a general rule, multiple accounts have to be merged into the same active account. There may be some exceptions, based on Premier status.


To get started, log into your first account
