A Full Guide To The Delta SkyMiles Loyalty Program

By Shawn Gallagher January 8, 2025

Delta is one of the biggest airlines in the world, and its loyalty program, SkyMiles, is popular among many frequent travelers. The program has seen many changes thorughout the years, whether good or bad. Let’s go over what this frequent flyer program has to offer and see how you can benefit from joining.

How Does Delta SkyMiles Work?

Just like most other airlines, you earn miles with Delta. These miles are earned based on how much you spend per ticket and other eligible purchases. You earn 5 miles per dollar spent as a base member, and you’ll get to earn more the higher up you go up the elite status ladder. These miles can be redeemed for award tickets and other purchases.

In addition to these redeemable miles, you also earn Medallion Qualifying Dollars (MQDs). These are also based on how much you spend, except that these count towards reaching Medallion status, which is what Delta calls their elite status tiers.

Status On Delta

Delta has 4 levels of Medallion status. The qualifying period is from January 1st to December 31st.

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

Let’s go over the benefits of each tier.

Silver Medallion

This is the lowest tier of Medallion status, earned with $5,000 MQDs. Some of these benefits can be earned with a Delta SkyMiles Credit Card.

  • Zone 5 priority boarding
  • 1 checked bag free of charge

Earning Miles and MQDs

The most straightforward way to earn miles and MQDs is to board Delta marketed flights. The amount you earn is based on the number of dollars you spend on the eligible purchase and also depends on your Medallion status. Note that Basic Economy will not earn you miles and MQDs.

For miles, they are as follows:

  • Base member: 5 miles per dollar
  • Silver: 7 miles per dollar
  • Gold: 8 miles per dollar
  • Platinum: 9 miles per dollar
  • Diamond: 11 miles per dollar

Delta’s cobranded credit cards will also earn you miles, with earning rates depending on the card. In addition, Delta’s shopping portal and booking a hotel stay through Delta Stays will also earn you miles.

Keep in mind that SkyMiles never expire, so don’t worry if life gets in the way of traveling.

For MQDs, the rate at which you earn them aren’t based on status. Everyone earns 1 MQD per qualifying dollar.

Credit cards are also an option for earning MQDs. The Delta SkyMiles Reserve Amex Card earns you 1 MQD per $10 spent, while the Platinum and Gold cards earn you 1 MQD per $20.

Redeeming SkyMiles

Redeeming SkyMiles can be tricky. Delta doesn’t have a published award chart like American Airlines does, and their award tickets are dynamic (amount of miles for an award ticket varies based on demand).

I find international award tickets to be very overpriced (especially ones in premium cabins). Instead, I’ve personally used SkyMiles for domestic flights. Delta credit card holders also get 15% off for these tickets as well.

Delta occasionally runs flash sales for redeeming award tickets. These are great opportunities to make the most of your miles, as they’re typically worth less compared to some other loyalty programs.

Bottom Line

Although the SkyMiles frequent flyer program has seen a lot of change over the years, it’s still worth it to take part in if you fly Delta a fair amount. Taking advantage of their cobranded Amex cards can be beneficial, and keep an eye out for promotions and flash sales for your miles.
