I'm an AU on my parents' First USA credit card. First USA has been reporting this to Experian and Equifax, but the account appears nowhere on TransUnion. Apparently this account is really boosting my Equifax and Experian scores...they're 661 and 634 compared to my TransUnion of 589. All other factors are pretty much equal. My question is: how do I get First USA to report this positive information to TransUnion?
