Sometime back I went to my Citibank credit card’s online site and saw this neat feature. One can request a credit line increase with a click of a button and they get back to you instantly. It’s a feature that you can use once in about six months. Once you get an increase, you can request more incerease, but for that you need to fill up a form. Anyways, for this card, I just got a credit line increase. Here’s a screenshot of the page.
