Many or all of the products featured here are from our partners who compensate us. This influences which products we write about and where and how the product appears on a page. However, this does not influence our evaluations. Our opinions are our own. Here is a list of our partners and here's how we make money.

One of the largest airlines in North America and the world, Delta Air Lines operates hubs at eight U.S. airports: Atlanta, Boston, Cincinnati, Detroit, Los Angeles, Minneapolis-St. Paul, Salt Lake City and Seattle-Tacoma. It is also a member of the SkyTeam alliance and has more than 25 international airline partners.

If you live in a Delta-dominated city or you fly the airline regularly, you should check out the airline's frequent flyer program, Delta SkyMiles. The program is free to join and lets you earn Delta miles, achieve elite status and more.

Sign-up for Delta SkyMiles

Before you can start earning miles with Delta, you’ll need to sign up for a SkyMiles frequent flyer account. It’s free to join, and you can register here.

How do Delta SkyMiles work?

Beyond serving as the loyalty program name, SkyMiles are also the currency that members can earn and later redeem for flights with Delta or partners, hotel stays and other rewards.

You can generally earn miles by flying, spending on credit cards (Delta has several co-branded cards for its loyalists), traveling with partners, or dining and shopping through designated programs.

Delta SkyMiles do not expire, which is great news for infrequent travelers or those who have loyalty across multiple airline programs.

How much are Delta SkyMiles worth?

Based on the most recent analysis, NerdWallet values Delta Air Lines SkyMiles at 1.5 cents apiece. To determine the value of reward miles, we compared cash prices and reward redemptions for economy roundtrip routes across several destinations and dates. We divided the cost of the cash ticket by the cost of the reward ticket to determine a “cent per mile” value for each flight, then averaged this value across several flights and dates. Read more about how we arrived at these figures.

This is therefore a baseline value for Delta miles, based on real-world data collected from hundreds of economy routes; it is not a maximized value. In other words, you should aim for award redemptions that offer 1.5 cents or more in value from your Delta miles.

Delta vs. competitors: How it stacks in 2023

Delta came in fifth place out of nine airlines in our most recent analysis on the best airline loyalty programs. But Delta is a bit of a funky airline in terms of its rankings. While some airlines rank consistently high or low across the board, Delta was all over the place.

It has low fees and operates incredibly well in terms of high rates of on-time performance and low rates of cancellations and baggage mishandling. Its in-flight offerings are pretty glorious thanks to seatback screens and Biscoff cookies.

If you book basic economy, you do get the free cookies and seatback screens, but that’s about it. Checked bag fees, no rewards and no seat choice mean Delta basic economy seats are rough.

And even for other fare classes that do earn miles, Delta’s mileage program isn’t all that rewarding anyway, as Delta miles just aren’t that valuable. However, if you have elite status, other perks are pretty nice.

Here's a closer look at how SkyMiles competed across categories:

How to earn Delta SkyMiles

Flying on Delta and its partner airlines is the easiest way to earn miles. But there are ways to rack up miles besides flying, such as using a Delta-branded credit card or spending money with Delta partner companies.

The Delta SkyMiles you earn never expire as long as your account is open; this is different from how things work with some other frequent-flyer programs.

How are SkyMiles calculated?

Flying on Delta: Although they have "miles" in their name, the number of SkyMiles you earn on Delta flights is based on how much you spend, not how far you fly. The base earning rate is 5 miles per $1 spent, but you earn higher rates depending on whether you have elite status, which Delta refers to as "Medallion" status. (We'll have more on Medallion levels later — or you can jump ahead to that part now.) As of Dec. 9, 2021, you will no longer earn SkyMiles on any basic economy tickets.


Rewards earned

Basic SkyMiles membership

5 SkyMiles per $1 spent.

Silver Medallion

7 SkyMiles per $1 spent.

Gold Medallion

8 SkyMiles per $1 spent.

Platinum Medallion

9 SkyMiles per $1 spent.

Diamond Medallion

11 SkyMiles per $1 spent.

You earn SkyMiles only on the base fare and fees imposed by the airline. You don't earn any rewards on taxes or government-imposed fees that are rolled into the cost of your ticket. So if you are a basic SkyMiles member and spend $150 on a flight, $50 of which is fees, you’ll earn 5 x 100 = 500 SkyMiles.

Flying on partner airlines: Each partner airline has its own rules for earning SkyMiles. In general, the rewards you earn on partner airlines are based on the distance of the flight — so they really are "miles." You can earn bonus miles based on the fare class (such as economy, business or first) and your Medallion status.

Spending on the right credit cards

Delta offers co-branded credit cards with American Express.

Our favorite Delta credit card is the Delta SkyMiles® Gold American Express Card. The card gives you 2 SkyMiles per dollar spent with Delta. When you pay for tickets with the card, you get the first checked bag free for you and up to eight other people traveling on your reservation. Terms apply.

There's a great welcome bonus for new cardholders, too: Earn 40,000 bonus miles after you spend $2,000 in purchases on your new Card in your first 6 months. Terms Apply. The annual fee is $0 intro for the first year, then $99.

Other ways to earn Delta SkyMiles

Delta's non-airline partners include:

  • Hotels and Airbnb: You can earn SkyMiles at thousands of properties in most major hotel chains. In some cases, you earn a flat number of points per stay; in others, you earn points based on how much you spend. You can also earn miles at Airbnb. See hotel partners and earning rules here.

  • Auto rentals and Lyft: Several major rental agencies have an option to earn SkyMiles. And if you prefer rental car alternatives, here's a deal from Turo: Delta SkyMiles Members who link their SkyMiles number to their Turo profile will be able to earn 2,000 miles on their first Turo trip and 500 miles on every trip thereafter. You can also earn miles using the Lyft ride-hailing service. Details here.

  • Dining: Register your credit card with SkyMiles Dining and earn up to 5 miles per dollar when you use that card at thousands of participating restaurants. (You can use any credit card; it doesn't have to be a Delta-branded card.)

  • Shopping: Earn miles at hundreds of online merchants through the airline's shopping portal, SkyMiles Shopping.

  • Transfer from other programs: Delta SkyMiles is a transfer partner for both American Express Membership Rewards and Marriott Bonvoy.

Purchase SkyMiles

You can buy additional SkyMiles through the Delta website, but this generally isn't a good value. SkyMiles cost 3.5 cents apiece when purchased like this, which means you're paying more than three times what the miles are worth on average.

How to redeem Delta SkyMiles

If your top-of-mind question is: “How do I use points from Delta SkyMiles?”, you’ve come to the right section of this Delta guide. Know this: Not all redemptions are created equal. Keep the following tips in mind to get more value out of your Delta SkyMiles redemptions.

Good redemption options

SkyMiles are redeemable for flights through Delta Air Lines and its partners. In most cases, you redeem by booking through Delta's website. Certain Delta cardholders can even get 15% off award travel booked with Delta through the TakeOff 15 perk.

To book award travel, go to the booking tool and choose the option for seeing the price in miles. Then enter information about when and where you want to travel, and choose your fare class: Basic economy, main cabin, Delta Comfort+ (premium economy), first class, Delta Premium Select or Delta One.

How many SkyMiles are needed for a flight? It depends on your destination, but SkyMiles members can redeem as few as 4,500 SkyMiles for a domestic short-haul flight.

  • Basic Economy: This is a no-frills fare. You sit in a standard seat and get free drinks and snacks. However, you don't get to pick your seat, you're the last to board the plane, you can't get upgraded even with Medallion status, and there are fees of $99 or $199 to change a flight. You cannot book Basic Economy fares with miles and you cannot earn any miles on Basic Economy fares.

  • Main Cabin: This is a standard economy seat. You get free nonalcoholic drinks and basic snacks, plus seatback entertainment when available.

  • Delta Comfort+: This is essentially "economy plus." You get 4 inches of extra legroom and dedicated overhead carry-on storage.

  • First Class: You get a bigger seat with more legroom; free alcoholic drinks, snacks and meals on longer flights; dedicated storage and flight attendant service; and priority boarding.

  • Delta Premium Select: This is first class with extra-comfortable seating and amenities, available on select international flights.

  • Delta One: This is first class with lie-flat seating, available only on select long-haul flights.

Unlike some other airlines, Delta doesn't publish an award chart showing you exactly how many miles you need for a given flight. You have to figure it out the hard way — by entering your flight information and seeing what it costs in terms of miles.

Delta advertises that there are no blackout dates for award travel.

You can also use miles to purchase seat upgrades; membership to Delta Sky Clubs airport lounges; vacation packages; exclusive experiences; merchandise, gift cards, hotel stays and car rental in the SkyMiles Marketplace; or donations to charity through Delta SkyWish. See details about these and other options here.

If you happen to have at least 2.5 million SkyMiles in your account — and who doesn't? — you can redeem them for private jet travel. According to Delta, those 2.5 million points are "enough to take up to four passengers round-trip from Atlanta to South Florida."

Bad redemption options

For the most part, using SkyMiles for anything other than flights will result in below-average redemption values. Delta and its partners might push promotions for these unorthodox redemption options, but don’t take the bait. Unless the offer is really extraordinary, you’re almost always better off using miles for flights.

🤓Nerdy Tip

Because Delta ties the cost of award flights very closely to the cash price, you might see some very high award prices when cash prices are high. Although these are not necessarily bad options, it does mean you should double-check that the value you’re getting from miles is equal to or greater than the value you’re getting by just paying cash.

Delta SkyMiles Medallion status

Anyone can join the Delta SkyMiles program for free, but to move up from basic membership to elite status (where the real perks are), you need to fly the airline regularly.

Changes in 2023

Beginning Jan. 1, 2023, the Medallion program will see significant changes to status-earning requirements and benefits, including increased earning requirements for some status tiers. You can read more on that here.

    • 25,000 bonus miles.

    • $200 Delta travel voucher.

    • Gift of Gold Medallion status to a friend.

How are MQMs calculated for earning SkyMiles Medallion status?

To earn Medallion status, you'll need to understand the terms MQD, MQM and MQS:

  • MQDs are Medallion Qualifying Dollars. You earn 1 MQD for every dollar you spend on Delta flights. This includes the fare and airline fees, but not taxes and government fees.

  • MQMs are Medallion Qualifying Miles. You earn these based on how far you fly and the fare class of your ticket. With regular economy class tickets, you earn 1 MQM per mile flown. For higher classes, it may be 1.5 or 2 MQMs per mile flown.

  • MQSs are Medallion Qualifying Segments. You earn these based on how many takeoff-to-landing flights you fly. A nonstop flight from Seattle to New York, for example, would earn 1 MQS. But if you changed planes in, say, Minneapolis, then you would earn 2 MQSs.

You earn status by spending a certain amount of money (that is, earning MQDs) and earning either a minimum number of MQMs or a minimum number of MQSs. Note that, as of Dec. 9, 2021, travelers won't earn MQDs, MQMs or MQSs on any basic economy fares.

SkyMiles status levels and MQD/MQM/MQS required to earn.





To earn this status, you must have MQDs of at least:





AND EITHER this many MQMs:





OR this many MQSs:





Medallion status for a given year is earned based on activity in the previous calendar year. Your status is generally good until Jan. 31 of the following year. For example, your Medallion status for 2023 is based on your activity in 2022 and will last until Jan. 31, 2024.

MQMs roll over from one year to the next. Say you earned 65,000 MQMs in 2022. That's enough for Gold status (which requires 50,000 MQMs) but not for Platinum (75,000). The "unused" 15,000 MQMs roll over to 2023 to give you a head start on your next year's earning.

Status matching

You can match your Delta status in another airline loyalty program. You must have current elite status with a qualifying airline, and you cannot have used the match in the previous three years. Once you’re accepted in the match program, you get complimentary Medallion status for three months. To keep it for the rest of the year, you need to earn it during those three months:

  • Silver: 6,250 MQMs / 8 MQSs and $750 MQDs / MQD waiver

  • Gold: 12,500 MQMs / 15 MQSs and $1,500 MQDs / MQD waiver

  • Platinum: 18,750 MQMs / 25 MQSs and $2,250 MQDs / MQD waiver

Is the Delta SkyMiles program right for you?

We've covered all the basic details of the Delta SkyMiles program, including how to use Delta SkyMiles for maximum value. But if you still aren't sure whether a frequent flyer program is worth the effort, see our beginner's guide to frequent flyer programs.

Frequently asked questions

You can technically transfer your Delta SkyMiles to another person’s account, but it’s almost always a bad idea. Delta charges 1 cent per mile and $30 per transfer, which wipes out the value of the miles.

Delta SkyMiles do not expire, but they might lose value over time.

Delta SkyMiles cost 3.5 cents each when purchased directly, far more than their typical value. That is to say: Buying Delta miles is generally not a good move.

MQM stands for Medallion Qualification Miles, which are required to earn Delta Medallion (elite) status. MQMs differ from standard SkyMiles in that they cannot be used to book flights, yet both MQMs and SkyMiles can be earned by either flying on Delta and its partners or using a Delta co-branded credit card.

Generally, you cannot buy Medallion Qualification Miles directly; however, Delta occasionally runs promotions that let you pay to upgrade your existing Medallion status tier.
