<prompt> Human: I want to build up my credit more and earn different types of rewards. My credit card usage is good and I am definitely not overspending or being lackadaisical about payments. Also, I would rather not have multiple bank accounts with multiple banks. Currently using a Chase Sapphire and Aadvantage American Airlines credit card for miles. I have a Chase Freedom sitting at home just to have it. Any suggestions?  <response>: You should hang out here.rchurning
