If you have multiple MileagePlus® accounts, you can now go online to submit a request to merge them. This will be especially helpful for those of you who had an account in both MileagePlus and OnePass® and forgot to link them before we transitioned to a single loyalty program.
The three-step process is quick and easy. Before you start, though, please make sure that the first and last names match between the accounts. Sign in to your MileagePlus account to make any changes.
By merging your accounts, all your earning will be in one place, which means you’ll get to an award faster. We’ll merge your current-year Premier qualifying activity, lifetime miles balances and your account history.
