In early 2016, I was approved for the Citi AAdvantage Platinum Select MC with a SL of $5,000 or $6,000, I can't remember which.
In early 2018, I received a CLD to $2,000 SL from Citi due to lack of utilization and a temporary drop in my FICO scores.
Today, I decided to try and claw some of that back and requested a soft-pull CLI via the Citi website. I updated my income and mortgage, and received instant approval for a CLI to $3,000. They offered me more with a HP but I declined.
Scores: TU: 707 EX: 691. Citi seems to use EX for their soft pulls.
Congrats on CLI !!!
