So I decided to go on a little app and CLI spree, and had some success!
Cap1 Venture instantly approved $5,000
Citi AAdvantage Platinum Select instantly approved $1,500
(I have the discontinued Citi AAdvantage Gold with a CL of $2,500, the terms of the SUB changed so I'm now eligible for the Platinum Select bonus as well. I was kind of annoyed that this new SL was less than the Gold, so after I got the card I requested a CLI to $2,500 which was approved a few hours later! Probably will see if there's a way to either combine the two cards or convert the Gold to a no AF version.)
Requested a CLI of my Best Buy visa from $1,000 to $2,000 which was instantly approved, immediately went again and was instantly approved for a CLI to $3,000!
I'm done for a while now.
