Amex CLI question

[BeeH11]

I've had my Amex since 2005. I didn't know about their 3x CLI back then. Sometime after I got my Amex, I did get 1 CLI from $2k to $6k (auto CLI). Then I never got another increase until 2-3 weeks ago when I got an auto CLI to $8k. (Yesterday I was approved for a PRGC, not sure if that has any effect on this). When can I ask for a CLI next? Do I have to wait 61 days? 3 months? Thanks in advance!

This is answered in the credit applications sub forum, but it's any time. Since you haven't requested one, they were auto increases.
