Woot! Way to go on the awesome approvals!
Congradulations! I started off with AMEX in May of 2018 with a Delta Gold $1000 SL. A year later my Gold was upgraded to Platinum and now my SL is $13200. And I got a pre approval for the Cash Magnet with an $8000 SL. If you treat AMEX well, it'll grow quick.
Some advice, pay your balance in full each month. AMEX loves it.
I've read AMEX can be very giving when it comes to CLI's, I'm here for it, if so. Lol Glad your AMEX experience has been pleasant and swift. I look forward to growing with them! Good call on paying in full, that's what I've been practicing recently and prefer it. Liked seeing the utalization low on TU and Equfiax.
Thanks again on the congrats!
