Many of us kind of know how much max credit lines Chase would extend to us - when we apply new cards and do not get instant approvals, we pre-emptively call the recon dept to shuffle credit lines. Of course, this is based on the assumption that the total credit exposure is the ONLY issue and nothing else is the cause of the deferred approval.

My last 3 Chase cards all were approved via such action BEFORE any notification is given. I usually call 24 hours after the application so to give time to let the application go thru the system process and a human at the recon dept can pull it right up to see the initial "result" before s/he exercises her/his discretionary decision.
