<prompt> Human: Hi, reddit! I just wanted to share my happiness with someone. I received an email from Bank of America letting me know I am eligible for a credit line increase without a credit check. I put in my projected income for this year and got a credit line increase of 3500. I then went to CapOne and did the same, 3000 increase, and Discover gave me extra 500. Ca-ching! TL; DR: Went from a credit line of 14,900 to 21,900 in 15 minutes.Edit: I have almost no credit card debt at all. For each credit card I use, I assigned a recurring expense and pay everything off every month. -BofA: phone bill on autopay-CapOne: gas and other misc. spending-Discover: monthly plan at a car wash 14Before the credit line increases, I was using 4 of available credit. After paying off CapOne cc bill this month, my cc utilization rate is .007.  <response>: Now dont use anymore credit then you normally do and keep your utilization under 20
