I have a CLEAR Sports (free) membership. Can I link my United MileagePlus number?

The United and CLEAR partnership is for use at airports, which is a paid membership. Log in to my.clearme.com to upgrade your account. Then, log in at my.clearme.com/mileageplus where you’ll be prompted to link your MileagePlus number to your CLEAR account. You’ll receive MileagePlus pricing when you’re billed for your membership.
