What are airline miles?

Airline miles or frequent flyer miles are rewards that you earn by being a regular customer of a specific airline and its loyalty program. Typically, you can earn airline miles when you book flights through the airline or its partners. To enroll, you’ll usually sign up with the airline you’re interested in or the one you travel with most frequently.

Airline miles vs. credit card rewards miles

Airline-specific miles and credit card miles are similar, but they’re separate programs. Credit card miles may be offered through travel rewards cards. Frequent flyer miles are offered through airlines. 

Both types of miles can be used to cover travel expenses, but credit card miles may provide more flexibility. Travel credit cards might let you earn rewards on every purchase you make, whether it’s travel-related or not. Some cards let you use those miles toward flights or things like event tickets, cash or gift cards. You could even combine credit card rewards miles and frequent flyer miles to make travel savings even greater.

How to earn airline miles

Here are a few ways you can earn miles:

Join your preferred airline’s loyalty program

Different airlines offer various rewards programs. You may want to sign up for a frequent flyer program with the airline or partner airlines you use most often. You’ll usually earn miles based on how much you fly. So the more you fly with an airline and its partner airlines, the more miles you can earn.

Some airline rewards programs may let you earn miles by shopping through the program’s online portal or dining out at certain restaurants.

Use a travel rewards card

Another way to earn miles is using a general travel rewards card. Capital One travel rewards cardholders can earn miles on every purchase.

Capital One also offers flexible rewards redemption options. Miles can be used to book travel, cover recent travel purchases, get gift cards and more.

How you can use your miles

You may be able to use your points or miles for the following:

Purchasing flights

You could use your rewards miles to cover the cost of your airfare or reduce the amount you pay out of pocket. And if you’re a Venture cardholder, you can even use your rewards miles to cover travel purchases made within the past 90 days, book trips through Capital One Travel and transfer your miles to travel loyalty programs.

Upgrading your seats

If upgrades are available, you may be able to use your rewards for a seat upgrade on your flight.

Paying for hotels and rental cars

You may be able to use your miles to help pay for hotel stays and rental cars on your trip. But you may need to book at specific hotels that your airline or travel credit card partners with. So it’s a good idea to review the details before you make a reservation.

How airline miles work FAQ

Here are a few frequently asked questions about how airline miles work so you can better understand your options:

With frequent flyer miles, you usually earn miles when you fly. But you may also earn miles in other ways, like by making purchases through an airline’s shopping portal. Then you can usually use those miles toward the price of your flight.

You may be able to use both credit card miles and frequent flyer airline miles on the same trip, but how you combine and redeem your rewards might vary based on the airline and credit card issuer.

A travel rewards credit card may help you save even more on your trips. Plus, you might be eligible for additional cardholder benefits. And because you can earn miles on every purchase, you could end up earning more with your card than through frequent flyer programs alone. For example, Venture cardholders can earn unlimited 2X miles on every purchase and unlimited 5X miles on hotels, vacation rentals, rental cars and activities booked through Capital One Travel.

The number of miles needed to cover the cost of a flight varies depending on the value of your miles and the cost of the flight.
