Something else to note is that first story doesn't say what his other reasons were for getting the line of credit cut. Sure where he shopped might have been one of them, but what were the others? FICO score drop? High debt to credit ratio? Too many inquiries? Or maybe he just isn't utilizing the credit he has access to and American Express doesn't want to put more money at his finger tips than he really needs access to. You could give me a million dollar credit limit and I wouldn't use it. I don't need more than a $4000 or $5000 line of credit because I pay my card off every month. If in the past two years he has proven that he doesn't spend more than $3800 per month, then why does he care what his limit is? If he really needed a limitless credit card then he should have gotten a charge card.
People put way too much emphasis on their line of credit. My credit score is near 800 and my Blue card has a $2000 credit limit on it. It is because I don't ever spend more than that much on it. Having a $50,000 line of credit would be nice to brag about, but seriously... What good does having something like that do you? So you can get into debt up to your eyeballs without maxing out the card. Good for you. LOL Having a high line of credit does nothing for your credit score and it isn't an indication of what your credit really is. Ideally your line of credit shouldn't be any higher than what you charge and pay off every month. In this economy it is a very very very wise idea to not carry any balances. It is even wiser if you are trying to build a high FICO score.
Ok, I'm off my soapbox now.
