Frequent flyer guide to Delta SkyMiles

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

Joining SkyMiles is easy and completely free to get started. Once you join, you can begin earning points and accessing special benefits right away. In this guide, you will learn about how to join the Delta SkyMiles program, co-branded credit cards that earn SkyMiles and ways you can 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 — through qualifying Delta purchases and spending with a co-branded Delta SkyMiles credit card — though there are a number of other 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 into Delta’s website before booking a ticket, your SkyMiles number will automatically be applied to your ticket purchase. 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.

When you fly with the airline, you will earn a base rate of 5 miles for every dollar you spend on Delta-marketed flight tickets (Main Cabin 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 Medallion Status, which allows you to earn up to 11 miles per dollar spent. There is no limit to the number of miles you can earn on a ticket.

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 cardmembers.

• Delta SkyMiles® Blue American Express Card: You can earn a welcome offer of 10,000 bonus miles if you spend $1,000 within the first six months of card membership. Plus, you’ll earn 2X miles at restaurants worldwide (including takeout and delivery in the U.S.), 2X miles on Delta purchases and 1X miles on all other purchases.
• Delta SkyMiles® Gold American Express Card: You can earn a welcome offer of 80,000 bonus miles if you spend $3,000 within the first six months of card membership. You’ll also earn 2X miles at restaurants worldwide (including takeout and delivery in the U.S.), 2X miles on Delta and U.S. supermarket purchases and 1X miles on all other purchases.
• Delta SkyMiles® Platinum American Express Card: You can earn a welcome offer of 90,000 bonus miles after you spend $4,000 on your new card within six months of account opening. You’ll also earn 3X miles on Delta flights, Delta Vacations purchases and direct hotel purchases, 2X miles at restaurants and U.S. supermarkets (including takeout and delivery in the U.S.) and 1X miles on all other eligible purchases.
• Delta SkyMiles® Reserve American Express Card: You can earn a welcome offer of 100,000 bonus miles after you spend $6,000 on your new card within six months of account opening. Plus, you’ll earn 3X miles on eligible Delta flights and Delta Vacations purchases and 1X miles on all other purchases.

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 too. 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. However, Delta’s major partner airlines include:

• AeroMexico
• Air France
• China Eastern
• KLM

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 Prices in Miles” if you’re using the Delta app. Remember that prices for all flight awards will be 15 percent lower once you become a Delta credit card customer.
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 Air France, KLM, Korean Air, and Virgin Atlantic. For award travel with Air Europa, Air Tahiti Nui, Czech Airlines and Kenya Airways, contact Delta Reservations.

Lastly, 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.

Redeem during Delta Flash Sales

Delta routinely offers SkyMiles sales, allowing members to redeem miles for flights at a set discount if the member travels between the current offering of city pairs on sale for a specific time period. The list of routes on sale can be found on the SkyMiles Deals website.

For example, one of the recent sale offerings is a roundtrip award ticket between New York and Amsterdam for 50,000 SkyMiles.

Redeem in other ways

You can use SkyMiles for more than just flights. SkyMiles can also be used to:

• Upgrade your seat
• Purchase premium drinks
• Redeem miles for checked baggage fees
• Purchase a Sky Club membership
• Donate miles through Delta’s SkyWish program
• Gift miles
• Buy gift cards
• Buy magazines
• Shop for merchandise in the SkyMiles Marketplace
• Bid on exclusive opportunities, like VIP passes, classes and backstage access at events through SkyMiles Experiences

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 to look for deals. For example, searching for a flight with destinations and dates that might fit your future travel plans will show you the price and then the number of SkyMiles needed for that flight.

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, the same flight might cost 43,500 miles plus $12 in airline taxes and fees, 33,500 miles plus $192 with a cash and miles option or $577 if paying with cash only. While the person who redeems only miles for their flight is getting about 1.2 cents per mile for their redemption, the person redeeming with miles and cash is only getting 1.1 cent per mile in value.

Also note that Delta credit cards offer a “Pay with Miles” feature that lets you book an award with miles and make up the difference with cash if you prefer. You’ll get 1 cent per mile you redeem ($50 off with 5,000 miles) with this redemption option, and you can simply pay the difference with cash if you’re short on the rewards required for a booking.

Finally, be aware that Delta credit card holders can get a better rate with their miles through a newer program called TakeOff 15. Essentially, this promotion lets Delta credit card members get 15 percent off all award flights.

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. When you first join the program, you will be a SkyMiles Member. All SkyMiles members receive free access to Wi-Fi on planes, a new benefit rolling out to all Delta planes by the end of 2025.

For the Medallion status tiers, reaching them is based on Medallion Qualification Dollars (MQDs). You can earn $1 MQD per $1 spent on a ticket for a Delta flight operated either by Delta or one of its airline partners.

• Silver Medallion

  The first status tier, known as Silver Medallion, unlocks unlimited complimentary upgrades, priority boarding, waived baggage fees, a preferred Clear Plus membership rate and free selection of preferred Main Cabin seats. You’ll also earn 7X miles per dollar spent, rather than the standard 5X miles per dollar. Reaching this status requires $5,000 MQDs.

• Gold Medallion

  Along with the benefits and complimentary upgrades of the Silver tier, you’ll also receive Hertz car rental benefits and access to the full Sky Priority suite of services. This suite provides priority security line access, priority check-in and expedited baggage perks. You’ll earn 8X miles per dollar spent. Reaching this status requires $10,000 MQDs.

• Platinum Medallion

  With Platinum, you’ll get all of the previous tiers’ benefits, plus customizable Choice Benefits. Choice Benefits allow you to pick an additional benefit from a list of options. For example, starting with the 2025 program year, you could choose to receive 30,000 bonus miles, give Silver status to a friend or family member, receive a $1,000 MQD accelerator towards the next Medallion Qualification Year, or receive a $300 Delta travel voucher. You’ll earn 9X miles per dollar spent at this level. Reaching this status requires $15,000 MQDs.

• Diamond Medallion

  Diamond Medallion, the highest Medallion tier, offers all of the previous tiers’ benefits, plus higher-priority booking, upgrading and boarding; a complimentary CLEAR membership; and additional Choice Benefits options, such as Delta Sky Club membership, 35,000 bonus miles and more. You’ll earn 11X miles per dollar spent at this level. Reaching this status requires $28,000 MQDs.

Frequently asked questions

• Do Delta SkyMiles expire?

  Delta SkyMiles do not expire. As long as your account is active and in good standing, your points remain available for use. Keep in mind if a member violates the terms and conditions of the program, their account may be closed and their points forfeited.

• Can you share Delta SkyMiles with friends and family members?

  You can gift your SkyMiles to up to four recipients at a time, and you can transfer your miles to up to four SkyMiles members at a time. This entire process can be done online via the transfer miles webpage. Terms and conditions, including transfer transaction fees, apply.

  Yes, you can purchase Delta SkyMiles in 2,000-mile increments and a total of 60,000 miles per year.

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. Starting in 2025, Delta’s Medallion status tiers are unlocked solely based on Medallion Qualifying Dollars (MQDs) which you can earn at $1 MQD per $1 spent on Delta-marketed tickets.

When booking reward flights with SkyMiles, Delta uses a dynamic pricing system that changes the number of miles required based on supply and demand. This can often result in a large number of points required to book a ticket, such as the example below for a reward flight between Chicago and Accra charging a whopping 410,000 miles for a 1-way ticket in Delta One.

While the number of points required can be steep, Delta’s program has no blackout dates, offering flexibility of reward space in exchange for more miles required.

Ultimately, the Delta SkyMiles program offers many ways to accrue points from flying Delta that can be redeemed for multiple offerings. Despite its high prices on some award routings, it can be a great program to consider. Just make sure to thoroughly compare the Delta SkyMiles program to general-purpose travel credit cards, airline credit cards and other airline loyalty programs so that you can find the best travel card and program for your needs.
