I marked in my calendar the last time I applied for a CLI with this CC and it was about that time again to request another one after 3 months since my last SP CLI. The "request a credit limit increase" link popped back up today so I went ahead and applied for it. Again, it was a SP and my CL went from $3900 to $5500. That is a definite success in my book. I believe I started this card at $900 and one SP CLI after another, I built myself up to what I have now. I figured since NFCU increased my CL from $5000 to $9000 back in April that it would look good to other CC lenders when I applied for other CLI's. I think I'm also going to try a Discover CLI soon (last one was early April).
