Related: Loving Chase Right Now…
Not a deal, but I figured that this is worth pointing out.
American Express has long allowed payments made from their site to instantly increase your available credit line. With Chase it has always taken several days for your credit line to be increased once again.
I just noticed a couple days ago that Chase.com now immediately increases your credit line when you make a payment on Chase.com. Love it!
Next improvement: Please allow people to make more than 1 payment to the same credit card on Chase.com within 3 days of the last one.
