Does the credit score calculation basing on the length of the relationship with the credit card company or the specific account?
AAoA stands for Average Age of Accounts (i.e. it's per account, not per creditor) but AmEx, unlike other creditors, backdates so all of your AmEx cards report as being opened in the year you established your AmEx membership. That said, AAoA isn't immediately impacted by closing an account as closed accounts in good standing continue to report for 10 years. AAoA is calculated on both open and closed accounts.
It's utilization (closing a revolving account decreases available credit) that will immediately affect your score.
