My first $10000 CL was Chase Freedom through auto CLI. I have never requested a CLI on any of my cards. The only $10000 SL card was Fidelity Rewards. I wish I could remember the credit cards I had in my younger years and what the limits were. Now I think I will record limits on cards I get and any CLI in a spreadsheet.
My BCP went from 2K sl to 6k at six months and then to 12K a the next go around. They didn't give me the 18K. Ahhh yes then it went to 17 six months after. then I failed the next time I was eligible. Waited 3 months and got to 21.8K this past spring. I asked for 25K. Next time comes November 26th.
Picked up my first NFCU card (Platinum) last month with 15k SL. By far my largest card. Rate wasn't great @ 15.49% but I am using it for BT right now living good with their 12 months @ 0%. That app spree last month wrecked my scores so I will proceed with caution about that 2nd card or a CLI until next Spring with any additional HP's. Pretty dang happy with that huge SL though.
