I was approved for the card in January 2016 with a SL of $500. I have had 2 statements post; 2/16/16 & 3/16/16.
I've ran approx $2,000 through the card and PIF once a week or so.
I requested a CLI today and went from $500 to $4,000!
Congrats!! I am waiting to do the same thing. Waiting for my second statement to come out later on this month. Fingers crossed!! MY SL is now $3k and dying to see what I can get.
