I just posted about some CLIs yesterday (https://ficoforums.myfico.com/t5/Credit-Card-Approvals/Recent-CLIs/m-p/6446804). I've been watching my Chase Amazon Visa Signature for a while since I started seeing a lot of auto increases for others. Maybe having my other cards increase triggered something in their system because I just got an auto CLI on my amazon card late last night!
$6,200 -> $11,000
I'm still waiting for a drizzle 😞 I've had mine 10 months now, so I'm hoping they increase it in January. For some reason Chase trusts me with their lowest APRs (for the personal cards at least)... but also generally their lowest SLs.
Congratulations on your Amazon auto-CLI!
