Background: I opened my Capital One Quicksilver One card in February of this year with a SL of $500 and requested an increase in April. I was automatically approved for a $1,000 increase.
Fast foward to last Saturday night (7/11/15) I decided to try for another CLI because I was nearly maxing out every month on my $1,500 credit line. I needed the ability to make more purchases as well as keep my utilization down. I applied online and received the 2 -3 business day notice. So Monday (7/13) I e-mailed the EO stating my request, my desired increase ($4,000), and reasoning for that desired increase. Yesterday (7/15) I received a call from a very nice woman from the executive office.
She asked me a few questions, verified some information, and told me she would be sending my request to the underwriters. She said I would hear something back in 7-10 business days. This morning (7/16) I logged into my account and my credit limit is now $5,500! I am beyond happy with the quality of customer service and the quick turnaround. I'm also enrolled in the credit steps program. I am due for an automatic incease after my 5th payment. I just made my 5th payment a few days ago and my statement closes tomorrow! I'm curious to see if I'll get that increase as well. I would assume yes, but I'll have to wait and see. 
Extra info:
- I pay my high balances down every month leaving about 1 to 2% utilization reporting on my card.
- In my EO letter I mentioned that a $5,500 credit limit would match my Discover It credit line (just started reporting)
UPDATE
My 6th statement closed yesterday (7/17). When I logged in today (7/18) I saw another $500 increase due to my Credit Steps enrollment! Woohoo! Hello 6k credit line! I love you Capital One!
Congrats
Congrats! I think its time I req a increase on the Venture.
