We love playing the credit card miles and points game and are always on the lookout for an exceptional bonus or a great redemption deal. We charge everything to credit cards–every little bit adds up, but we ALWAYS pay in full at the end of the month. I emphasize the “always” because I encourage everyone to take advantage of the great freebies to be had by using credit cards, but only so long as you never charge more than you can pay at the end of the month. If you can’t afford to pay in cash, don’t charge it to a card. Period. Interest rates eat people alive and can cost way more than any perk you might get from accumulated points. That warning aside, here’s how we paid for two first class flights (one 5 hours long and one 12 hours long) with credit card points.
