COngrats on your approval and Welcome to Amex family !!!
Congrats OP. 8 to 10 years ago I had hit rock bottom with public records, charge-offs and lates also. Now that you're back in the game get in the habit of making your payments on time + paying over the min. payment where possible and you will do just fine.
Super Congrats on your Amex Hilton Honors $1,000 SL!
I'd like to echo the advice of previous posters. Just continue
to pay on time and keep your overall credit utilization very low.
Your FICO scores and CLs will rise before you know it. Speaking of
which, don't forget about your Amex 3x CLI after 61 days. By this
time in March 2019 your $1,000 CL can become $3,000. Thanks for sharing!
