To check miles through United's MileagePlus program, log into the account through the United website, and enter the MileagePlus Number, along with the PIN or password. If not a member of MileagePlus, it is possible to sign up on the United website.
To register for the United MileagePlus program, an individual must enter contact information, such as a name, address, gender, birthday and email address. Also, the company requires a four-digit PIN, a password, a username and a security question. The company also asks for a PIN or password reminder.
In addition to this information, an individual may also choose to subscribe to a number of newsletters from United, such as United News & Deals, or information from United's advertising partners. There are also ways to sign up for the MileagePlus Program and to get MileagePlus statements emailed to a specific address.
A person may use MileagePlus miles to purchase free travel on United, but there are other ways to use the miles, as well. For example, a person can use the miles to purchase dining certificates, hotel stays, car rentals and even cruises. People may also redeem the miles for subscriptions, shopping and more. Individuals may also upgrade the membership to receive premier benefits through the program.
