Delta SkyMiles® Guide: How to Earn, Redeem, and Maximize Rewards in 2025

The Delta SkyMiles program rewards you with SkyMiles every time you fly with Delta. These miles can be used in a variety of ways, but their primary use is booking award seats on a Delta Air Lines flight or on one of the airline’s many partners. The Delta SkyMiles program offers a baseline rate of 5 miles per dollar spent on flights. However, the rewards increase as you climb through the Delta Medallion elite status tiers, with each tier offering higher SkyMiles earning rates than the previous, plus additional perks. The highest earning rate — that of Delta Diamond Medallion members — is 11 SkyMiles per dollar spent on flights. Additionally, Delta offers co-branded credit cards through American Express that allow you to earn more SkyMiles on everyday purchases.

Once earned, you can use your miles in a variety of ways. SkyMiles are versatile — they can be used toward hotel stays through Delta, to upgrade your seat on Delta flights, and even to purchase Delta vacation packages. As one of the biggest U.S. airlines, Delta has over 300 destinations and eight domestic hub airports, plus they are a founding member of the SkyTeam airline alliance, which includes 18 airlines that offer nearly 1,000 global destinations. So, there are plenty of options to choose from when booking an award ticket.

Do Delta SkyMiles expire?

Most airline miles expire after a set period of inactivity. However, Delta SkyMiles never expire, which makes the loyalty program more stress-free. You don’t need to keep your account active in any way to retain your hard-earned miles. Rather, you can simply earn SkyMiles at your leisure and redeem when you’ve accumulated enough. It is important to note, however, that Delta is among a growing number of airline loyalty programs that now offer miles that don’t expire. But they were a pioneer with this policy, as one of the first airlines to eliminate mileage expiration.

Delta SkyMiles membership levels

The SkyMiles program has several tiers. Simply signing up for Delta SkyMiles makes you a general member, which allows you to earn and redeem miles. You’ll earn 5 SkyMiles per dollar spent on flights purchased through Delta Air Lines as a general SkyMiles member. General membership also includes access to programs such as SkyMiles Shopping and Dining, allowing you to earn even more points by linking your card to your account. Plus, Delta is in the process of rolling out free Wi-Fi fleet-wide to all Delta SkyMiles members.

However, depending on how many Delta Medallion® Qualification Dollars (MQDs) you earn through flying and other means, you may qualify for one of the Delta Medallion elite status tiers: Silver Medallion, Gold Medallion, Platinum Medallion and Diamond Medallion. The number of SkyMiles you earn increases at each elite tier. You’ll also unlock perks such as priority boarding, complimentary upgrades to first class and Delta Comfort, and free checked luggage. At the Platinum and Diamond Medallion tiers, you’ll also be able to choose a Choice Benefit, which includes upgrade certificates on Delta and select partner flights. Each Delta Medallion elite status tier offers greater benefits than the previous.

Delta SkyMiles are generally worth about 1.1 cents per mile when redeemed for award flights; however, their value can change depending on how you redeem them. At times, it is better to use cash instead of redeeming miles for airfare. International business class flights on partner airlines generally offer the best value, but you may find reasonable value for even domestic economy Delta awards. There are also other ways you can redeem SkyMiles beyond flights, but most offer poor value.

Even though finding the best value for your miles may not be easy, those wanting to get the most out of their miles find it is worth it.

Delta miles value

Delta SkyMiles have an average value of 1.1 cents per mile when redeemed for flights, but their value is highly dependent on how they are redeemed. SkyMiles generally have the best value when redeemed for international business class flights, typically premium cabin flights on partner airlines. Delta often has high award prices for their own premium cabin flights, so look to redeem miles on their many airline partners. That said, redeeming miles for economy tickets can be a fine choice, especially for domestic travelers. Domestic economy redemptions tend to offer slightly more value than international economy award tickets, and redemptions for Delta’s Premium Select cabin tend to have the lowest average value. SkyMiles provide even less value when redeemed for hotel, car rental, or other non-travel redemptions.

• Best value → international business/first class flights
• Average value → economy flights, domestic flights
• Poor value → gift cards, merchandise, non-travel redemptions.

Due to Delta’s dynamic pricing, the value you can get for your miles can vary significantly. For example, using miles to purchase an economy flight from Salt Lake City (SLC) to Paris (CDG) for a flight in early 2026 provided a value of 1.2¢ per mile, compared to a value of 1.4¢ per mile for business class. Delta Premium Select on the same flight offered a value of just 0.90¢ per mile. In this case, business class was the best deal.

But in some cases, economy flights may offer a fine deal. For some dates reviewed, a domestic cross-country flight from Los Angeles (LAX) to New York-JFK (JFK) yielded a value of 1.4¢ per mile, while first class only gave a value of 1.0¢ per mile. Because there is no hard and fast value for SkyMiles, it will take some work to get the best value for your miles. It’s important to review both the cash price and the award price (subtracting out the taxes and fees) to determine the value you’re getting for your miles. However, taking the time to get the most out of your miles is worth the reward.

Flying with Delta Air Lines is the most straightforward way to earn SkyMiles. Delta Air Lines offers a revenue-based system for earning SkyMiles on its flights, which means you earn miles based on how much you spend, not how far you fly. General SkyMiles members will earn 5 SkyMiles per $1 of base fare on Delta-issued tickets (excluding taxes and fees; basic economy tickets are also excluded) while Delta Medallion members earn more depending on their status level.

Note that there are some “exception fares” within the revenue-based earning structure. Exception fares include cruise fares, bulk fares, consolidator fares, vacation packages (not including packages with Delta Vacations) and discounted or inclusive tour packages.

These fares earn SkyMiles based on distance flown according to the following table:

Even though Delta SkyMiles is a frequent flyer program, flying isn’t the only way to earn miles. There are a plethora of options for earning SkyMiles without setting foot on an airplane. You can spend on Delta credit cards (which can also provide other Delta-specific perks), use the SkyMiles Shopping and Dining programs, plus earn on everyday purchases with other Delta partners, such as Starbucks and Uber. By taking advantage of the numerous ways to earn Delta SkyMiles, you can quickly accrue enough for a free flight.

Delta SkyMiles credit cards

Delta offers co-branded airline credit cards that give cardholders access to additional SkyMiles perks. All Delta credit cards are issued by American Express. You can earn at least 1 Delta SkyMile per $1 spent on eligible purchases with any of these cards. The cards offered range from the $0-annual-fee Delta SkyMiles^® Blue American Express Card (see rates & fees) to the Delta SkyMiles^® Reserve American Express Card, which is loaded with benefits but has a $650 annual fee (see rates & fees). One of the best perks of all Delta SkyMiles credit cards (except the Delta SkyMiles^® Blue American Express Card) is the TakeOff 15 perk that immediately gives you 15% off award tickets on Delta flights through delta.com and the Fly Delta app.

SkyMiles can be redeemed in a variety of ways, but you’ll get the best value when redeeming for free flights. Keep in mind that Delta does not have a fixed value for its miles, and their value depends entirely on their use. In general, you’ll get a better value from premium cabin flights, whereas economy class flights will yield poorer value. Non-flight redemptions tend to yield the lowest value. To find the best value for your miles, compare the number of miles needed to the cash value of the redemption you’re making.

How to book a flight using Delta SkyMiles

One of the easiest ways to redeem your SkyMiles is to use them to book a flight with Delta. You can easily search for award flights at Delta.com. Because Delta doesn’t publish an award chart, prices depend entirely on your origin, destination and travel dates.

Here are some sample one-way prices for different types of trips:

How to redeem Skymiles with partner airlines

You can use SkyMiles to book flights with more than 20 Delta partner airlines, and in many cases, you can do that directly via Delta.com or Fly Delta app. It’s often as easy to book these flights as you would a regular Delta flight. To get started, simply head to Delta.com and input your starting point and destination, or search for flights using the Delta app. From there, select “Shop with miles” and begin searching for flights with Delta and partners. Award flights on partner airlines can sometimes offer excellent value for your SkyMiles.

A few partner airlines may require you to contact Delta Reservations for assistance.

Delta Experiences and other redemption options

Delta Experiences are another redemption option for your Delta SkyMiles. Delta SkyMiles Experiences are unique event packages similar to Delta’s vacation packages. Ranging from culinary tours, to VIP tickets at sports events, to wellness vacations, you have a wide variety of experiences for redeeming your SkyMiles. Unlike other redemption options, most experiences require you to bid your miles. Some experiences can provide excellent value from your miles, but it will depend entirely on the value of the experience.

Delta SkyMiles can also be redeemed for checked bag fees, seat upgrades, hotel stays, car rentals and Delta Vacations. You can also give your SkyMiles to charity.

SkyMiles can potentially have a higher value when redeemed as Experiences, but this will depend on the experience. With Delta Vacation redemptions, you’ll consistently get the average value of 1.1 cents per mile. Redeeming miles for seat upgrades or baggage fees will also get you around the average value. Of the options, redeeming miles for hotels and car rentals is the poorest use; hotel and car rental reservations get you only 0.7 cents per mile.

The Delta SkyMiles program rewards frequent Delta fliers with perks through their Medallion elite status program. There are four Medallion tiers: Silver, Gold, Platinum, and Diamond. Medallion status is earned by accruing a certain number of Medallion® Qualification Dollars (MQDs). MQDs can be earned by two primary means: flying with Delta Air Lines and partners and spending on a Delta SkyMiles^® Platinum American Express Card or Delta SkyMiles^® Reserve American Express Card. To earn Delta Medallion status, you’ll need to earn the following number of MQDs within a calendar year:

• Silver Medallion: $5,000 MQDs
• Gold Medallion: $10,000 MQDs
• Platinum Medallion: $15,000 MQDs
• Diamond Medallion: $28,000 MQDs

The benefits of Delta Medallion status range from higher award mileage earning rates to free checked bags to priority boarding to the potential for complimentary upgrades. As you rise through the Delta elite status tiers, you’ll enjoy an increasing number of perks. Finally, Delta does have an invitation-only exclusive elite status level beyond Diamond called Delta 360°™ with benefits beyond all that Diamond already offers.

Benefits of Delta elite status

Once you reach an elite status, you get access to some pretty useful perks that can mean cheaper and more comfortable trips going forward. Here’s a quick breakdown of what you’d get with each tier:

Earning elite status with credit cards

Earning Medallion status with Delta is based on spending with Delta and its partners. But if you have a Delta SkyMiles^® Platinum American Express Card, Delta SkyMiles^® Platinum Business American Express Card, Delta SkyMiles^® Reserve American Express Card, or Delta SkyMiles^® Reserve Business American Express Card, you’ll get a $2,500 MQD Headstart per eligible card type. There’s also a $1 MQD Boost for those who have either a Delta SkyMiles^® Platinum American Express Card or Delta SkyMiles^® Platinum Business American Express Card per $20 spent on either of these cards. The MQD Boost is twice as good on both the Delta SkyMiles^® Reserve American Express Card and Delta SkyMiles^® Reserve Business American Express Card, where you can earn $1 MQD for every $10 spent on the card.

Generally speaking, though, paid flights with Delta and partners that are marketed by Delta will earn $1 MQD per $1 spent. And you have to earn at least $5,000 MQDs to qualify for the lowest Medallion tier.

Once you reach one of these Medallion statuses, you’d have it for the next year. If you qualify in 2025, for example, you’d get that level for 2026. So it’s not something that is guaranteed for more than a year, and you’d have to keep reaching those thresholds to maintain it.

You should also note that there are exceptions to what kinds of purchases will count toward Medallion status. For instance, Basic Economy tickets don’t earn either award miles or MQDs. You’ll have to factor that into your spending plan if you want to pursue elite status.

Getting the most out of your miles begins with knowing the many ways to earn SkyMiles and understanding how to best redeem them. Make sure you don’t overlook the ways to earn SkyMiles that don’t involve setting foot on a plane. Some of these can let you earn on everyday purchases you already make, such as coffee at Starbucks.

You’ll also want to identify the best redemption options for any miles you do earn and avoid any ways to use SkyMiles that get you less than the average value of 1.1 cents per mile. Remember — using miles for Delta and partner airline flights tends to yield the best value.

If you travel frequently with Delta Air Lines, getting a Delta SkyMiles American Express credit card is almost certainly a benefit. The perks can quickly outweigh the annual fee. Delta and American Express have tailored the card benefits to make them ideal for loyal Delta fliers, whether you’re an occasional flier or one who aims for Diamond Medallion each year. A Delta SkyMiles credit card lets you both earn miles faster and enjoy benefits when you travel with Delta. With most cards, you’ll immediately get 15% more from your miles.

Stack rewards to earn faster

The best strategy for earning lots of SkyMiles is to take advantage of the everyday habits you already have. If you use Uber and buy coffee at Starbucks already, link your accounts to earn SkyMiles. If you have a Delta SkyMiles credit card, you could be using this for everyday shopping to earn even more SkyMiles, or through the SkyMiles Shopping portal for any online purchases.

A credit card welcome offer is another great way to quickly earn a pile of SkyMiles. If you’re in the market for a new card, this could be another reason to consider a Delta American Express card. Not to mention, you’ll enjoy additional perks when you travel with Delta Air Lines. Any everyday spending will be doubly or triply rewarded — you’ll earn miles for your purchase on the card, miles from a shopping or dining program (if used), and work toward earning the bonus miles from the card’s welcome offer.

Finally, if you aren’t part of a hotel or car rental program, consider crediting any hotel stays or car rentals to Delta SkyMiles as well. The same goes for package vacations or cruises, if these are in your plans.

Best redemption strategies

Delta has removed much of the outsized value once possible from SkyMiles through their move to a dynamic pricing system. You’ll find that most flight redemptions hover around the average value of 1.1 cents per mile. However, you can find some partner flights where you can still get excellent value for your miles. If you have travel that does not originate or end in North America, consider looking for flight options using SkyMiles. You might be surprised by the deals you can find. Other than that, bookmark SkyMiles Award Deals and use these to maximize your miles.

Best uses of SkyMiles

• Long-haul partner airline business class outside the Americas
• Delta SkyMiles Award Deals — both domestic and international
• Domestic tickets in either economy or first class

Common mistakes to avoid

With Delta’s dynamic award pricing system, you should always check the award ticket price against the cash price. Though the average value of SkyMiles may be 1.1 cent apiece, there are flight redemptions where you get much less than this. If a redemption would get you less than 1.1 cents per SkyMile, you’re likely better off paying cash and saving your miles. Not comparing the cash and award prices is one way to easily lose out on value.

You should also avoid redemptions where the value is consistently poor. These include hotel and car rental redemptions in which you’ll get around 0.7 cents per SkyMile. It would be better to use the miles for seat upgrades or Delta Vacations, where the value is at least over 1 cent apiece.

Finally, not using your miles gets you nothing for them. If you keep stockpiling SkyMiles and never redeem them, then you ultimately get no value out of them.
