How I Took $195K Worth Of Vacations ... Almost Entirely On Credit Card Points
Through my research I learned that racking up credit card points to score free airfare and hotel stays was actually quite easy, thanks to a strategy called “churning.”

Put simply, churning is when you apply for multiple credit cards in order to capitalize on their lucrative sign-up incentives, which issuers give you in return for meeting a certain spending requirement.

When done right, you can bank hundreds of thousands in rewards points—but there’s a catch.

Churning is only a financially sound strategy if you’re able to meet the spending minimums without blowing your budget, and you can pay off your balance in full every month. Otherwise, the interest you’ll pay will overshadow any benefits.
