Iberia/Pulaski are very conservative and frugal with credit limits. If you want more than a 2K line keep looking. First Command Bank pulls TU and has a card with no annual fee and a prime +1 rate, currently 4.25%.
txjohn, you talk me into applying for Alliant Credit Union. I was approved but the APR was a little higher than I wanted since they pulled EQ which was my lowest score at 701.
