I think the 'wait' is for small CLI...like a couple hundred dollars. You've just tripled your credit limit. I think that's pretty good.
I definitely think you did the right thing. I received one small ( 1k ) CLI on my QS after about 6mos, 15k to 16k ( I'm not complaining about my 15k SL!!! ). I have had my Spark Business card with them for 11 years and have never been granted a CLI (no missed payments and always PIF), but I don't put much spend on it because I have better rewards cards. The sole reason given for CLI denial is that I "do not use enough of current credit limit." So, in my experience, Cap One likes to see heavy usage.
