Question about shuffling credit among Chase biz cards before I mess something up . . . I just got approved for a CIP, my 3rd Chase biz card. The CL is $5k, and my other two Chase biz cards (both CICs) have CLs of $6k and $10k. I've got a massive travel purchase coming up next month (my reason for getting the CIP). I know I can move credit from my other 2 cards to my CIP. Is there a minimum amount I need to leave behind on my CICs? Also, I looove my CICs, so I don't want to leave them with tiny CLs. After I make the travel purchase on my CIP and pay that off, can I then move credit back to the CICs from the CIP? Do I/should I wait a certain amount of time before doing so?
