Maybe I should just give up trying to figure out how the folks at Discover make decisions. Or maybe they really are from another planet! Here's what happened this week:
Last week, I applied for a CLI on my Discover IT card. I've had the card since December 2018 and the SL has grown steadily. My last CLI was in June 2019 and brought me to a SL of $11,500. This is my second Discover IT card; the first one has a SL of about half that.
So last week I applied for a CLI as I do occasionally, just to see if Discover is amenable. As you know, it doesn't hurt to ask since Discover uses monthly soft pulls to determine eligibility for a CLI. My request was denied due to the usual "Too many accounts with balances," and "Balances on accounts too high", etc. At the time, the utilization on my card was about 48%.
Today, just a few days after receiving the letter from Discover about my latest CLI denial, I was astonished to receive an Email letting me know they'd granted me an auto-CLI to $14,000! The Email said, "Good news! We've increased your credit line. We've noticed your excellent credit management overall and increased your credit line to $14,000." Go figure!
Thanks, Discover, for the unexpected and welcome auto-CLI. But I sure wish I could figure out how they make decisions at Discover HQ...!
