I don't think it's really too much about what you spend unless you're balling. I think they're more interested in people paying off what they use in a timely fashion, meaning way more than the minimum payment. There are plenty of people on here that get increases and barely use their cards. But when they do, it gets paid off quickly.

Oh, you definitely need to use them. If you don't use it for a while, they'll slash the limits, but they'll restore them if you call in.

I know that Amex likes to see spend on their cards when requesting it, but...how much do they like to see? I know it's obviously a YMMV situation, but should I show that I can use a certain amount of my limit when paying it in full? Searched the 3x CLI thread and didn't see anything recent.
For me spend wasn't important. I got a $20,000 cli on my 2nd month of the card with a Total: $200 spend. Got approved 3x CLI at 61 days from $10,000 to $30,000 
I paid ontime and early. Most of times before statements cuts.. sometimes a week after making the purchase.. i almost had $0 balance when the statements came in.
A day before asking for CLI i pifed whatever balance i had. I asked for the 3X at $0 balance. For the 61 days i am positive all my spend was $200 on the dot.
I've heard of it! I'm getting wary since I don't want them to slash mine, as this is my largest limit. Hopefully they'll be nice to me! They've been good so far
