Hello. I've had the Discover IT card since 2013. I believe initial SL was $5,900. To the best of my knowledge, I got auto increase of $3K early 2022. Later that year I applied for a CLI and was approved for an additional $2.5K to bump my CL to $9,900. Honestlu, didn't use the card much. Since then I have applied for CLI and would always be declined for not enough usage.
Recently I started to use the card more and charged about $2500 to it. I then applied for a CLI a few weeks before my statement cut in July of this year and was auto approved for an additional $2K increase bringing my CL to $11,900. I paid down all except $400 by due date. My statement then cut in August and I tried another CLI and was auto approved for another $2K for a total CL of $13,990. I wasn't expecting that. My FICO 8 TU score is 776. My overall CL utilization is at 21% so I have been hunting for CLI's and new BT cards.
Anyway, I just wanted to share. Back to back CLI within a month. Wonder if I can keep pressing my luck. Unfortunately, I have no BT offers on this card at the moment.
