Are those FiCo scores? or Credir Karma scores?
I honestly would not put anywhere over 50% of spending through that card, even if you PiF before statement cuts. The best way is still to improve your FiCO score, perhaps by getting CLis or getting a new card with good CL.
Credit card game is a long one, you will need some patience, amex Gold is not a hard card to get, I am sure you will get it sooner rather than later.
Ask yourself what your core set of cards will look like and start working towards those.
See above comment for scores. You can also get various scores at some credit card account online tools. I believe Discover (log in and should be somewhere on the main UI) provides TU and Amex (goto account services once you log in) provides EX.
Amex gold doesn't need very high score, your score is actually very close already. Perhaps just give them some love on the delta gold (no need to be excessive). Try to pay off all but one of your cards before statements cut,a nd ensure reported balance at statement cut is less than 10% of the CL.
You already have discover for 3 years, see if you can get some cli there.
Amex doesn't do HP for existing members (you are) unless approved, so there is no harm trying gold again in a few month when you bump your score to 680.
To get a CLI or a new card, you are relatively new so they want to see how you handle their card as well as other cards. They're probably ok with the way you handle other cards, so you need time with them. I would use their card heavily and always PIF. Heavy use on a $1,000 card shows you need more room, whether it be a CLI or a new card. You might get a CLI on your existing card, but after six months or more, they'll be more comfortable with you. If you don't have too many HPs on your CRs, maybe after 6 months of heavy use and good payments on their card, you might try again. But I wouldn't try before then, unless you get an offer.
OP, your scorecard indicative of negative info being present, so is the limit they gave you on your card.
There are plenty of people in your situation who have significant spend but cannot get new cards or increases till Amex is ready.
I dont think anyone can quantify whether it's going to be three months, six months, year
It really depends on your CR, and whatever is holding your scores down. Amex is very much score and clean file driven lender.
It doesn't mean you wont have success with them, it just means it may take some time.
If you dont want to try another cold app, wait till you have pre-approved offer in your account. Otherwise, I'd give it six months at least.
