A little birdie told me that Chase Checking accounts are churnable. If I remember correctly, it was every 90 days after account closing and accounts could be funded with a credit card up to $500.
Some customers churn the account because they receive coupons of $125 for opening a new account after fulfilling the fine print every six months.
This could be worthwhile to some folks to make some easy cash. I personally do not churn the account because I have already memorized the account number and have too many accounts linked to it.
