Travel hacking consists of signing up for credit cards to receive benefits such as points, free hotel rooms, trip insurance, free upgrades, companion passes, extended warranties, purchase protection, and more! There are so many benefits to having a credit card, but the one that rises above all others is the ability to sign up for a credit card and receive a signup bonus after meeting the spending requirements. Signup bonuses and spending requirements vary from card to card. Before our Trip around the world, we signed up for eight different credit cards, met the spending requirements, and received over 600,000 bonus points while still having excellent credit scores and no debit. If done correctly, travel hacking can be an incredible resource to help you travel more for free!
