I applied for this card and was accepted in July of 2013.
I had been using it as my "main" card, with a $15000 limit. My second card is AMEX BCP for groceries (6%) and gas (3%).
I recently applied for an increases and was declined by Cap One because "monthly expenditures are not high enough to warrant limit increase."
I called Cap One and explained that I charge about $4000 monthly and that I did not want to charge that amount on a $15000 card because that would be close to 33% utilization, and that I needed another $2000 to feel more comfortable as that being my "main" card for everyday purchases other than groceries or gas. They said that they would "reconsider" this and get back to me in 10 days.
My AMEX has a $30,000 limit.
If Cap One turns me down again, should I still use it as my "lead" card? I like the 1.5% on everything, but do not want to ruin my utilization.
P.S. I also have Discover IT ($15000) and Chase Freedom ($56500) but they are in the 'sockdrawer' with one monthly recurring charge on each, to keep them active.
