Key takeaways

  • The Delta SkyMiles program helps members earn miles that are redeemable for flights to over 1,000 destinations around the world.
  • As part of Delta’s membership in the SkyTeam airline alliance, SkyMiles can be redeemed for flights on Delta as well as other partner airlines — such as Air France, KLM and Virgin Atlantic.
  • You can also earn Delta SkyMiles by using a co-branded Delta credit card for spending or purchasing tickets with the airline and its partners.

Delta SkyMiles is the official loyalty program of Delta Air Lines, one of the world’s top airlines. The program provides its members numerous benefits and savings, and its currency — SkyMiles — can be redeemed for multiple purposes, including purchasing flights, seat upgrades and more.

Joining the Delta SkyMiles program is easy and completely free to get started. Once you join, you can begin earning miles and accessing special benefits right away. In this guide, we’ll break down how to join the Delta SkyMiles program, which co-branded credit cards earn SkyMiles and how to maximize your miles.

How to sign up for Delta SkyMiles

It’s free to join the Delta SkyMiles program. The registration can be found on the airline’s website and submitted through the online membership form.

Once you’ve joined the program, you can start earning Delta SkyMiles in two primary ways:

  1. Through qualifying Delta purchases
  2. Through spending with a co-branded Delta SkyMiles credit card

There are, however, a number of less-common ways to earn rewards, as well.

How to earn Delta SkyMiles

Earn miles on Delta purchases

To earn miles on Delta Air Lines flights, you’ll need to sign up for the Delta SkyMiles program. Once you’ve joined, you’ll receive a SkyMiles number that you will enter each time you book a flight with the airline or its partners. If you log in to Delta’s website before booking a ticket, your SkyMiles number will automatically be applied to your ticket purchase.

When you fly with the airline, you will earn a base rate of five miles for every dollar you spend on Delta-marketed flight tickets (Main Cabin class and above). For partner flights, you may earn miles at a different rate. You can also boost the number of miles you earn by achieving Diamond Medallion Status, which allows you to earn up to 11 miles per dollar spent. And the good news is that there is no limit to the number of miles you can earn on a ticket.

Money tip:

If you’ve already booked your trip, and you’re wondering how to add your SkyMiles number to an existing reservation, note that you can do this after the fact by accessing the “My Trips” tab on Delta’s website.

Earn miles with a Delta SkyMiles credit or debit card

With Delta Air Lines credit cards, you can earn miles on everyday purchases. There are several Delta American Express cards for general consumers, all of which offer rewards programs and bonus miles for new cardholders, including the Delta SkyMiles® Blue American Express Card, Delta SkyMiles® Gold American Express Card, Delta SkyMiles® Platinum American Express Card and Delta SkyMiles® Reserve American Express Card.

Earn miles via other rewards programs

Another way to earn Delta SkyMiles is by converting rewards from another loyalty program to Delta SkyMiles. The best way to do this is through the American Express Membership Rewards program.

You can earn Amex Membership Rewards points with any eligible American Express credit card and convert them to Delta SkyMiles in increments of 1,000 at a long-standing transfer ratio of 1:1.

Keep in mind:

American Express levies a small excise tax for U.S. card members transferring their points to Delta.

In addition to partnering with other credit card rewards programs, Delta offers a partnership with Starbucks. With this program, when you load $25 or more to your Starbucks account, you can also earn SkyMiles. For example, loading $100 to your Starbucks Rewards account will earn you 200 SkyMiles.

Earn miles with partner airlines

Delta Air Lines has many airline partners you can earn miles with. Some of Delta’s biggest partner airlines include:

Each airline has different rules on rewards and redemptions. For more information, check out Delta’s website to learn how partner airlines work with the Delta SkyMiles program.

Earn miles with other travel partners

Beyond airline partners, Delta has a number of cruise, hotel and car partners that allow you to earn SkyMiles. The frequent flyer program also offers vacation packages where you can pick up additional miles.

How much are Delta SkyMiles worth?

The value of Delta SkyMiles can be difficult to determine because Delta does not have a fixed award chart. Instead, the program uses a dynamic pricing system for award tickets that is based on multiple factors. According to Bankrate’s points and miles valuations, SkyMiles are worth around 1.2 cents on average.

The best way to get an idea of how much your rewards balance is worth is to play around with the Delta website and look for deals. For example, searching for a flight with destinations and dates that fit your future travel plans will show you the cash price and the number of SkyMiles needed for that flight.

Dividing the cash price by the number of miles required will give you a sense of whether the flight is a good deal for your miles. Ex. A $500 flight for 40,000 miles means your miles are worth 1.25 cents each. ($500 / 40,000 = .0125)

Delta also lets members book with miles, cash or a combination of the two. However, members tend to get less value for their miles this way. For example, imagine a flight that costs:

  • 43,500 miles plus $12 in airline taxes and fees
  • 33,500 miles plus $192 with the cash and miles option
  • $577 if paying with cash only

While the first option gives a value of about 1.3 cents per mile for the redemption ($565 / 43,500 =.0129), the second option only gets 1.1 cents per mile in value ($385 / 33,500 = .0114).

Option Miles Used Cash Paid Value per Mile Notes
All miles 43,500 $12 1.3 cents Best value
Miles + cash 33,500 $192 1.1 cents Lower value
All cash 0 $577 N/A Most expensvie

Delta cardholders can get more bang for their buck

Delta credit cards offer a “Pay with Miles” feature that allows Delta co-branded cardholders to use their miles toward discounts on the price of their Delta tickets. You’ll get $50 off for every 5,000 miles you redeem, which is equal to 1 cent per mile. Simply pay the difference with cash to complete the booking.

Be aware that Delta cardholders also get a better rate with their miles through a program called TakeOff 15. Essentially, this promotion lets Delta credit card members get 15 percent off all award flights. Continuing with the example above, a $577 flight that normally requires 43,500 miles (plus $12 in fees) could be booked for 36,975 miles through this program, resulting in a redemption value of 1.5 cents per mile.

How to redeem Delta SkyMiles

Redeem for flights

Redeeming Delta SkyMiles is simple when you want to buy a flight ticket. Booking through Delta will give you the option to pay with SkyMiles, cash or both.

  1. Select “Book” on Delta.com or in the Fly Delta mobile app. Enter your trip information. Then, select the option to “Shop with Miles” on Delta.com or “Show Price in Miles” if you’re using the Delta app.
  2. Search for a flight. You’ll see the price in miles. Choose your flight(s) and complete your purchase with miles. If you don’t have enough miles to cover the cost of the ticket, you can switch from “Show Price In Miles” to “Show Price In Miles + Cash.” If you’re a Delta credit card customer, you can also redeem rewards starting at 5,000 miles for $50 off your flight on the checkout page.

Redeem with Delta Air Lines transfer partners

You can redeem SkyMiles on partner flights, which provides you with greater flexibility when it comes to purchasing your next flight. Partners you can book through Delta.com include:

Medallion members or Delta SkyMiles credit card members who live in Japan can redeem miles for select Skymark Airlines flights. Make sure to read the terms and conditions and check Skymark’s flight schedule before booking.

Other ways to redeem your SkyMiles

What to know about the Delta SkyMiles Medallion program

Medallion Status opens up more opportunities for SkyMiles members, although the program perks you’ll receive depend on which tier you’ve achieved.

There are four status tiers in the Medallion program: Silver, Gold, Platinum and Diamond. Reaching each tier is based on Medallion Qualification Dollars (MQDs). You’ll earn $1 MQD per $1 spent on a ticket for a Delta-marketed flight operated either by Delta or one of its airline partners. Here are the differences between each tier:

Best credit cards that earn Delta SkyMiles

The bottom line

If you’re a loyal Delta traveler, you’ll find plenty of opportunities to earn frequent flyer miles with the Delta SkyMiles program, an eligible Amex Delta credit card or both. That said, this program’s true potential is unlocked once you reach an elite Medallion status tier that includes luxury travel benefits and boosted reward rates.

While the number of points required to redeem a flight can be steep, Delta’s program has no blackout dates, offering flexibility of reward space in exchange for more miles required. Be sure to thoroughly compare the Delta SkyMiles program to other airline credit cards and airline loyalty programs so that you can find the best travel card and program for your needs.
