So I just went on Amex website and requested a 3 x cli on my Amex blue and was denied but then platinum is there and I click on it and it says pre approved, just weird I can’t get a 3 x on my other card but pre approved for the platinum, seems that’s a harder card to get, by the way I’ve yet to get a cli on any of my two cards with Amex and I’m rolling on being with them for 7 mos now and have kept my cards at 0 balance or 1% with pay in full, I have ran $2000 through each card monthly but kept my balance low when it reports, will wait and see what the letter says for denial, scores are 664 Equifax, 680 transunion and 684 Experian, uti is at 6% right now, no other baddies, or lates, I do have a short and thin file, my oldest account is right at 4 years, so just probably need to build a solid relationship with Amex
