I recently cancelled my Chase Southwest card ~2 weeks ago. I would like to apply for a Business INK card and then after that I would like to apply for a United Explorer card. How long should I wait (or does it even matter) after cancelling the Southwest Card before applying for the Business INK Card? Assuming I get approved, How long should I wait until I apply for United Explorer. I am currently 4/24 with Chase, but may go down to 3/24 in several months.
