I got three Chase cards, all opened within the last four months. Last time, I had to call the re-consideration line to close one of my accounts. Now, I am thinking of getting the Southwest card. It has been over 30 days since my last Chase application. I got some expenses to pay this month, but charges will still be under 30% per card. I am using only one Chase card now. Should I charge the expenses to my Chase card first before applying for another one to show big spending? Will that increase my chances of getting another Chase card?
