Yes, there is such a credit card and not just one! Banks issue travel credit cards that are not tied to any airline but still allow to earn miles and redeem them for airline tickets or other travel expenses. You can review travel credit cards to see how many options you have. And here, we will offer to your attention just one card that we think is the best offer out there - the Discover it® Miles card.

You probably know that Discover is well known for its cash back credit cards that charge no annual fee. The Discover it® Miles credit card will allow you to earn miles, which basically work like cash back. You will earn 1.5 miles per $1 spent on purchases, everywhere, without restrictions, rotating categories or caps. As the first-time user, you will get all your first-year miles matched at the end of the year. Thus, if you earn 35,000 miles, you get 70,000 miles.

Once you've accumulated some miles, you can start redeeming. Actually, you can redeem your miles starting at 1 mile, there are no minimums. Thus, to redeem your miles for a Delta ticket, you should buy the ticket with your Discover it® Miles card. Then, when transaction appears on your account, you can apply your miles to the cost - that's it! No hassles with reservation, no blackout dates, and no limits. You just buy and then redeem.

To sweeten the deal, the Discover it® Miles card has 15 months of 0% intro APR on purchases (when the introductory interest rate is over, the ongoing APR of 18.24% - 28.24% Variable APR will apply), no annual fee, and no foreign transaction fee. This card can become a good travel companion for anyone.
