So I was just wondering how much time had passed before I requested a CLI, so I went on chat.
Turns out they have NO record of me requesting any CLIs! I was surprised and asked 3 times to verify... (guessing because of AMEX TE/Costco change)
Therefore I went to request a CLI from my $10k (previously $5k in December 2015, then to $10k), and requested $25k and bam! I got it.
My highest limit card now! Second highest being my twin chase cards. (Although I did get a $17k offer for my Venture...)
Edit: For my BCE.
