I apparently need to read up on how to get Amex for increases without the 4506 request. In November I started at $10. On 691St da, I only asked for $20k and it was approved. I am positive that I could have gone higher.
I just asked for $30k and it was instantly approved. I am not sure what my limit is before it triggers the FR but I am leaving money on the table. The bright side is this is now my highest tradeline at $30k. 18 months ago I didn't have a credit card and was trying to figure out how to get startef.
