You’ve probably heard about people “traveling on points.” Somehow these friends, bloggers, and Instagrammers bounce around the world — and don’t pay for it?

If you’re wondering how air miles credit cards work — and which ones to choose — you’ve come to the right place.

Want to skip straight to our picks for the best cards? Go right ahead.

How Air Miles Credit Cards Work

Each airline has its own rewards system, often known as a “frequent flyer” program, that’s designed to instill loyalty among passengers.

You can earn “miles” with the airline’s rewards program by:

  • Taking flights
  • Spending money on a co-branded credit card
  • Making purchases with an airline partner, such as a car rental agency or online retailer

Once you’ve earned miles, you can then use them to book flights on that airline. The number of miles required depends greatly on distance, demand, and fare class.

Just to give you a ballpark estimate, however, you might fork over 25,000 miles for a roundtrip domestic economy flight, and 50,000 for a roundtrip economy flight to Europe.

Though you can’t transfer miles between airlines, you can use one airline’s miles to fly with one of its partners. If you earn American Airlines miles, for example, you could use them to fly on British Airways, since the airlines are in the same “alliance.”

You’ll sometimes see “blackout dates” mentioned; these occur when you can’t use miles, and can only buy tickets with cash. They’re most common around holidays.

Are Air Miles Credit Cards Right for You?

There are two basic types of air miles credit cards: co-branded airline cards and general travel cards.

Most airlines partner with credit card issuers to offer co-branded cards to their customers. American Express issues Delta’s cards, for example, and Chase issues Southwest’s. When you use these cards to make purchases with their associated airlines, you’ll earn extra miles on every dollar you spend.

These co-branded credit cards also often offer perks like free checked bags, priority boarding, airport lounge access, and discounts on in-flight purchases.

Other cards aren’t affiliated with a particular airline, and instead earn points from the credit card issuer. Though they don’t have the airline-specific perks of co-branded cards, you can use their travel rewards points on a variety of airlines, rather than just one.

Most travel rewards cards — whether airline-specific or general — come with high annual fees and interest rates (APRs).

That’s why we only recommend rewards credit cards for people who plan to pay off their cards each month. By paying your statement balance in full, you’ll avoid paying any interest on your purchases.

All in all, air miles credit cards might be good if you:

  • Fly frequently: If you find yourself flying one airline several times a year, it’s worth looking into a co-branded card. But if you fly a range of airlines, a general travel rewards or cash back card might be a better fit.
  • Have good credit scores: Rewards cards have stricter requirements than more basic cards. Check your credit scores, and only apply if they’re in the suggested range.
  • Will pay off your balance in full each month: Since travel rewards credit cards often come with high APRs, we strongly advise against carrying a balance on them. Paying interest can quickly negate any rewards you earn.
If you want to carry a balance on your credit card, consider getting one with a 0% APR introductory offer.

How Air Miles Credit Cards Help You Get “Free” Flights

Remember those travel hackers we mentioned? Well, we can pretty much guarantee they’re using credit card signup bonuses to cover their flights and hotels.

You can earn these bonuses by opening a card and spending a certain amount on it within 3 or 4 months.

As noted above, when we say “spend money on a card,” we don’t mean carrying a balance. We mean making purchases on the card, paying them off when your bill comes — and avoiding interest.

In addition to the introductory bonus, you’ll earn miles for spending money on the card. Most cards earn at least one mile per dollar (commonly written as 1X mile/dollar) on all purchases, plus extra miles in particular categories — such as 2X miles/dollar when making purchases with that particular airline.

Just to be clear how this works, let’s look at an example. The Gold Delta SkyMiles® Credit Card offers 30,000 bonus miles after spending $1,000 in the first 3 months.

  1. You apply for the card. A few weeks later, it arrives in the mail, and you activate it on March 1.
  2. The next few months, you put all your purchases — groceries, gas, gifts — on the card, earning 1X mile per dollar. Each month, you pay your bill in full.
  3. By June 1, you’ve put $6,000 in purchases on the card, earning you 30,000 bonus miles. You also earned 1X mile per dollar, for a total of 36,000 miles.
  4. You can now redeem those miles for a “free” Delta flight. When I looked, I found a great deal: a roundtrip from New York to Paris for 36,000 miles, plus $84 in fees.

Since the Delta card’s annual fee is waived for the first year, you just got a $500+ ticket for nothing more than fees. And don’t forget the card’s other perks, like a free checked bag and priority boarding.

When the card’s annual fee rolls around, you can decide to keep it — and pay the fee — or close the account, and pay nothing. Because you earned the miles with an airline (rather than points with a credit card company), you’ll be able to keep them either way, as long as your account remains active.

Now you see how it can be addictive?

How Air Miles Credit Cards Affect Your Credit Scores

Though it might surprise you, the truth is your credit scores won’t suffer too much when you apply for a new airline card (if they’re already in good shape). Applying for new credit dings your credit slightly due to the hard inquiry, but opening new cards can actually decrease your credit utilization (which is a good thing for your credit scores).

However, every time you open a new account you’ll shorten your average age of accounts and reset the time since your most recent account was opened. The only thing that can improve these credit score factors is time, so avoid opening several new cards in a short period if you want to improve your scores. Thankfully, these factors play a relatively small role in your credit scores compared to utilization and payment history.

If you’re considering an airline card, or any new card, make sure you understand credit scores inside and out — and keep careful track of your cards, statement due dates, and renewal dates. If you’re not getting enough value from an annual fee, consider closing the card.

And avoid applying for new credit if you want to get a large loan, such as a mortgage, in the next two years. In that case, every extra point on your credit scores could save you money.

As with any credit card, airline credit card issuers will check your credit before approving or denying your application. If you have poor or limited credit, you likely won’t qualify for a rewards credit card — and should instead focus on building or repairing your credit.

The 8 Best Air Miles Credit Cards

When choosing an air miles credit card, the most important step is determining which airline you fly the most. If your home airport is a hub for a particular airline, that’s a good place to start.

If you don’t fly one airline often, then consider a general travel rewards card.

Or consider getting both: Many people hold an airline card for its perks, plus a travel rewards card for its broad earning potential.

When deciding which card to get, you should analyze its annual fee, introductory bonus, perks, and potential to earn rewards. Most airline cards come in several versions, with annual fees that range from low to high.

You should also try to avoid cards with foreign transaction fees, which you’d pay when making purchases in another currency. (Unless otherwise noted, the cards below don’t charge foreign transaction fees.)

When you’re ready to apply for an air miles credit card and start earning rewards, here are eight of our favorites — plus a few other card offers that frequent travelers might find more appealing.

  • Purchase APR: 17.99%–24.99% Variable

Southwest is one of the country’s most beloved airlines, and with this card, you’ll get even more out of your ticket purchases. Note that because basic luggage is already free for all Southwest customers, this card doesn’t advertise free checked bags.

  • Annual fee: $75
  • Introductory bonus: Spend $1,000 in the first 3 months to earn 30,000 bonus miles and a Companion Fare

  • Perks: Annual Companion Fare and free first checked bags
  • Purchase APR: 16.99%–24.99% Variable

If you live on the west coast, you’ve probably flown — and loved — Alaska Airlines. It’s most famous for its annual Companion Fare, which lets you take a friend for free on a roundtrip economy ticket. All you pay is the taxes and fees (up to $121 for the annual Fare), which, if used strategically, more than wipes out the card’s annual fee.

 

  • Annual fee: $25
  • Introductory bonus: 3,500 miles after your first card use
  • Rewards: 2X miles/dollar at grocery stores and gas stations; 1X on everything else (including Aeromexico tickets)
  • Perks: Companion fare for travel to Mexico (worth $99), free first checked bags
  • Purchase APR: 24.74% Variable
  • Foreign transaction fee: 3%

If you want to get a rewards card without a solid credit history, this secured card is a stellar option for Aeromexico flyers. It offers excellent rewards and benefits for a secured card, including a free companion ticket to Mexico every year. Even better, after building your credit with this card, you’ll be able to apply for an unsecured card.

Looking for an unsecured card for flying Aeromexico? Check out the Aeromexico Visa Signature® Card, which offers 2X miles at Aeromexico, one free upgrade per year, and a deal to buy three tickets and get the fourth for free.

Enjoy the Journey

Once you start traveling, you’ll probably never want to stop — and air miles credit cards can help you get there. But due to the addictive nature of the miles and points game, you should only dive in if you’ll use your cards responsibly. Treat your credit cards well, and they’ll reward you with plenty of exciting experiences and “free” travel opportunities.
