Delta AM Ex Platinum= Free Travel

I wouldn't recommend a credit card to most people. But for those people who collaborate and work together and have the money already set aside for a credit card, they can maximize points and thus earn free travel if they're wise in their use of a card. My wife and I minimize our credit card so that we only have one or two at any point in time. And our goal is always a zero balance. And we use the points on our Delta American Express Platinum card to travel to multiple destinations and back for free. We use points that we've accumulated by buying routine things such as groceries or fuel. Where would you like to go for free?
