I received a auto CLI from Discover last month for $1.5K. I hit the request button a couple of weeks later and was given $500! The line is now at $5.1K! I tried Amazon Synchrony next, $1K approval to $4K. Last was Macy's. $4K approved to $5K. I should have asked for more but I was too conservative. I've had all 3 of these accounts for 4 years and for Discover, that was my 2nd auto CLI but my first request by me. The CLI's on the other 2 were my first requests. I've read here Macy's can be generous in a short period of time so I will be more aggressive later!
