Quick Answer: How Do Delta SkyMiles Work?
Delta SkyMiles is Delta Air Lines’ free loyalty program. Members can earn miles by flying eligible Delta fares, using Delta SkyMiles American Express Cards, booking with partners, and using travel partners. Miles do not expire. You can redeem SkyMiles for Delta award flights, seat upgrades, Delta Vacations, checked bags at select airports, and other travel rewards.
Is Delta SkyMiles Worth Joining?
Yes. Delta SkyMiles is worth joining even if you fly Delta only once or twice a year because membership is free and miles do not expire.
You should join if:
- You fly Delta or SkyTeam partners.
- You book Delta Main or higher fares.
- You use Delta Vacations, Hertz, Airbnb, Starbucks, or other partners.
- You want free Wi-Fi access where available.
- You may use Delta award flights later.
- You want to track toward Medallion Status.
The only major warning: Delta Main Basic / Basic Economy does not earn SkyMiles or Medallion credit. If earning miles matters, avoid Main Basic unless the fare is much cheaper.

How to Earn Delta SkyMiles
Delta SkyMiles can be earned through flights, cards, travel products, and partners.
| Earning Method | How It Works |
|---|---|
| Delta flights | Earn miles on eligible Delta-marketed paid tickets |
| Medallion Status | Higher status earns more miles per dollar |
| Delta Amex Cards | Earn miles on eligible card purchases |
| Delta Vacations | Earn miles and MQDs on eligible packages |

For most travelers, the easiest way to earn is by adding your SkyMiles number before booking a Delta flight.
How Many Miles Do You Earn on Delta Flights?
Delta mileage earning depends on fare type and Medallion Status.
For eligible Delta-marketed flights, general members typically earn miles based on the eligible ticket price, excluding government taxes and fees.
| Member Type | Miles Earned on Eligible Delta Fares |
|---|---|
| General SkyMiles Member | 5 miles per $1 on many eligible fares |
| Silver Medallion | 7 miles per $1 |
| Gold Medallion | 8 miles per $1 |
| Platinum Medallion | 9 miles per $1 |
| Diamond Medallion | 11 miles per $1 |
Delta’s newer fare language also matters. Some “Extra” travel experiences can earn differently, while Delta Main Basic does not earn miles.
✈️FlyingTip: Before booking Delta Main Basic, compare the fare difference with Main Classic. If the price gap is small, Main Classic may be better because it earns miles, MQDs, allows better seat control, and gives more flexibility.
For fare comparison, check Delta Basic Economy vs Main Cabin.
What Changed for Delta SkyMiles in 2026?
The biggest 2026 SkyMiles points to know are:
- Delta Main Basic / Basic Economy does not earn SkyMiles.
- Delta Main Basic does not earn MQDs toward Medallion Status.
- Medallion Status is now based on MQDs, not miles flown.
- 2027 Medallion Status is earned during the 2026 calendar year.
- Delta and Airbnb expanded earning opportunities in 2026.
- Delta Amex cardholders can use MQD Headstart and MQD Boost if eligible.
- Delta miles still do not expire.
This is why older SkyMiles guides can confuse travelers. The main question is no longer just “how many miles do I fly?” It is now “how much eligible Delta spend counts?”
Delta Medallion Status Requirements
Delta Medallion Status is earned through Medallion Qualification Dollars, or MQDs.
For 2027 Status earned during 2026:
| Medallion Tier | MQDs Required |
|---|---|
| Silver Medallion | $5,000 MQDs |
| Gold Medallion | $10,000 MQDs |
| Platinum Medallion | $15,000 MQDs |
| Diamond Medallion | $28,000 MQDs |
MQDs can be earned through eligible Delta flights, select partner flights, eligible Delta Vacations packages, and eligible Delta SkyMiles American Express Card benefits.
Delta Main Basic tickets do not count toward Medallion Status.
How to Use Delta SkyMiles
You can redeem Delta SkyMiles for:
- Delta award flights
- Flights to 1,000+ destinations
- Seat upgrades
- Delta Vacations packages
- Checked bags at select U.S. airports
- Delta Sky Club options for eligible Medallion Members
- Some experiences and partner redemptions
The most common use is booking award travel.
Delta does not publish a fixed award chart, so the number of miles needed can change by route, demand, travel date, cabin, and cash price.

Best Way to Redeem Delta SkyMiles
The best use of Delta SkyMiles is usually an award flight when the cash fare is high and the mileage price is reasonable.
Use this quick value test:
| Redemption Result | What It Means |
|---|---|
| Less than 1 cent per mile | Usually weak value |
| Around 1 cent per mile | Acceptable if cash fare is high |
| More than 1.2 cents per mile | Better redemption |
| Much higher value | Strong deal, especially on expensive routes |
Example:
If a flight costs $300 or 25,000 miles, your value is about 1.2 cents per mile.
That is decent.
If the same flight costs $300 or 45,000 miles, the value is weak. In that case, paying cash and saving miles may be smarter.

When Should You Pay Cash Instead of Using Miles?
Pay cash when:
- The mileage price is too high.
- The cash fare is low.
- You want to earn miles and MQDs.
- You are working toward Medallion Status.
- You need a fare with better flexibility.
- You can save miles for a better trip.
Use miles when:
- Cash prices are high.
- You need flexibility.
- The redemption value is good.
- You have miles sitting unused.
- You want to reduce out-of-pocket cost.
Do Delta SkyMiles Expire?
No. Delta SkyMiles do not expire. This is one of the strongest reasons to join SkyMiles even if you are not loyal to Delta.
You do not need to rush into a poor redemption just to keep miles alive.
Does Delta Basic Economy Earn SkyMiles?
Delta Main Basic, commonly known as Basic Economy, does not earn SkyMiles or Medallion credit.
This is one of the biggest mistakes travelers make.
Basic Economy may still be worth it if the fare is much cheaper and you do not care about miles, seats, upgrades, or status. But if you are trying to earn rewards, choose Main Classic or higher.
Delta SkyMiles and Airbnb
In 2026, Delta expanded its Airbnb partnership. SkyMiles Members can connect eligible Delta and Airbnb accounts and earn miles on qualifying Airbnb Homes, Experiences, and Services.
This is useful for travelers who already book Airbnb stays and want extra Delta miles without flying.
Always check the earning terms before booking because account-linking windows, eligible bookings, and posting timelines can matter.
Common Delta SkyMiles Mistakes
Avoid these mistakes:
- Booking Main Basic and expecting miles.
- Redeeming miles for poor value without checking cash price.
- Forgetting to add your SkyMiles number before travel.
- Assuming all partner flights earn the same.
- Ignoring fare type when chasing MQDs.
- Using miles for low-value redemptions when a cash fare is cheap.
- Choosing a credit card only for miles without checking annual fee value.
- Waiting too long to request missing miles.
Should You Chase Delta Medallion Status?
Chase Delta Medallion Status only if you fly Delta often or spend heavily through eligible Delta channels and cards.
Medallion Status may be worth it if you value:
- Complimentary upgrades
- First checked bag benefits
- Priority boarding
- Bonus miles
- Preferred seats
- Better service during travel issues
- Choice Benefits at higher tiers
Do not chase status if you rarely fly Delta. For casual travelers, earning and redeeming SkyMiles is enough.
