I know that I have 4 personal - 3 credit cards, SPG, Cash, Surpass, 1 Charge -premier and 3 biz cards - 1 biz gold, 1 SPG and 1 Delta
I tried to get similar cards for my wife who has her own business and I was told that the new limit was 3 - 2 credit and 1 charge. This was around the time they stopped re-allocating credit lines.
I would be curious if any one has NEW applications approved beyond that.
My 7th (HHonors Surpass) was approved about 8-10 months ago. Well after the great freeze of 2008
