[What that means] When we review requests for credit line increases, one of the things we look at is the payment history of your account. If you regularly use your card and make payments on time, it builds your account's payment history. If not, we don't have a history to review. We assess this to determine if an account qualifies. [What you can do] If you plan to use your card more, make sure you use your card responsibly. Add AutoPay and customized alerts to help you make more than your minimum payment on time each month. You can also use Capital One® Credit Tracker to help monitor your credit score. [If your letter says:]
