One of my most popular posts on Making Sense of Cents is How To Take A 10 Day Trip To Hawaii For $22.40 – Flights & Accommodations Included.
When I share that post, reactions are split: many readers think it’s incredible, while others suspect it’s too good to be true and believe travel rewards credit cards are a scam. Because so many people doubt that these cards work as advertised, I wanted to write a clear, in-depth guide to explain how they function and how to use them responsibly.
Note: travel rewards credit cards are especially common in the United States; similar products are less widespread in many other countries.
Travel rewards credit cards have become very popular recently. I’ve been using them for a few years, and it seems like almost everyone planning a vacation is talking about them.

I genuinely enjoy using travel rewards cards. They’ve helped me take many affordable vacations, earn significant cash back, and book highly discounted premium-class flights.
For instance, Wes recently completed a long sailing trip in Europe. When it ended, I booked a last-minute flight back to Arizona using points from our travel rewards cards. He was able to fly business class on a 12.5-hour flight from London to Los Angeles for less than $100 after points. Booking earlier would have cost even less. After a month on a boat with limited space, we wanted him to have a more comfortable seat, and our travel rewards made that possible at a very low cost.
Some of the people on the sailing trip were skeptical when he described how much we saved; they assumed it sounded like a scam.

As someone who regularly uses credit cards but has never paid interest, I wanted to address common questions and clear up confusion about travel rewards cards.
Below are the most frequent questions I hear about travel rewards credit cards.
Don’t you have to pay interest when you use a credit card?
Many people misunderstand how credit cards work and assume interest is unavoidable. That’s not true. If you pay your credit card balance in full by the due date each month, you won’t incur interest charges. I use credit cards often and have never paid interest because I always pay the full balance before it’s due.
Credit cards do carry high interest rates when balances are carried over—USA Today reports an average APR around 16.71%—but that only applies if you don’t pay the balance in full.
Are travel rewards credit cards for everyone?
Rewards cards let you earn points, miles, cash back, or other benefits simply by using the card for purchases you already plan to make. If you responsibly pay your card each month, using a rewards card for everyday expenses—groceries, gas, recurring bills—can be like earning free money.
Travel rewards are valuable because they convert ordinary spending into flights, hotel stays, gift cards, or statement credits. If you’re disciplined about payments and tracking your spending, rewards cards can be an excellent tool.
Another benefit is easier record-keeping: credit card statements help you see where your money goes, reducing the guesswork that often comes with cash purchases.
What are the disadvantages of travel rewards credit cards?
There are clear benefits, but also potential downsides. The primary risk is misuse: if you can’t pay your balance in full, interest will erode or eliminate any reward value. If you overspend to chase a sign-up bonus, you can end up worse off financially. Many cards require a minimum spend—often several thousand dollars within the first few months—to qualify for a welcome bonus. If meeting that threshold forces you into debt, the bonus isn’t worth it.
Poor credit card management can also harm your credit score. To use cards safely, follow these basic rules:
- Always pay your bills on time.
- Pay the full balance each month.
- Monitor your credit utilization rate.
What’s the catch with travel rewards credit cards?
Credit card companies aren’t giving away points out of generosity; they hope to earn long-term customers. They profit through interest, merchant fees (a percentage of each transaction), annual fees, and other charges. The main “catch” is that rewards only benefit you if you use the card responsibly. The worst outcomes come from overspending to earn rewards or carrying balances that incur interest.
When choosing a travel rewards card, research which type fits your habits: some are tied to specific airlines or hotel chains, while others offer flexible points usable across multiple partners. Select a card that matches how you travel and spend so you gain value rather than incur costs.
