I can't speak for the OP, but I logged into my account yesterday. My 6th month statement was due, and I was hoping to see my CL go from $500 to $750. It was at $2000! Needless to say, it made my day. I've read of a number of people who also got a $1500 CLI the same day, also at the 6th mo. stmt. date.
I've used my card a lot, from $300-$700 a month, but I've made payments 2-3 times a month, always made sure the statement balance was PIF, and usually paid nearly the full balance, and allowing $10-40 to report.
I was discharged from BK7 11/2012, if it matters to anyone.
