Delta Skymiles Loyalty Program

An explanation of Delta miles, credit cards and Medallion Status.


Fact checked

If you’re looking into frequent-flyer programs, consider Delta SkyMiles as they have great value and can be earned through many credit cards. Additional benefits are offered to those who fly enough to earn Medallion Status.

How much are Delta SkyMiles worth?

Delta SkyMiles are worth an average of 1.4 cents apiece, according to our February 2019 valuation. This is a competitive rate when compared to miles from other frequent-flyer programs.

How to calculate the value of your miles

  1. Search for a flight on the Delta website.
  2. Pick a flight and note its cost in dollars.
  3. Under the Show price in section on the flight results page, click Miles.
  4. Note how much your flight costs in miles.
  5. Divide the flight cost in dollars by the flight cost in miles. For example, if a $110 flight costs 9,000 miles, your miles are worth about $110/9,000 = 1.2 cents each.

How to earn Delta SkyMiles elite status

  • Medallion Qualification Dollars (MQDs).

Let’s break down what these are and how to earn them.

What you’ll get with Medallion Status

Delta’s frequent-flyer program can seem complicated, so you might be wondering: Is it even worth trying for Medallion Status?

For certain flyers, even Silver Medallion Status can be attractive. You’ll earn more points per flight, qualify for flight-upgrade priority, get waived baggage fees, enjoy status with Delta’s international partners and more.

Here are the perks you’ll receive for different Medallion Tiers.

Mileage earnings

General SkyMiles members earn 5x miles on eligible Delta or Delta-partner flights. Members with Medallion Status earn even more.

Rollover MQMs

When you earn more MQMs than you need to qualify for a Medallion Tier, Delta will roll them over to the next qualification year.

Flight benefits

Medallion Members may get upgraded to higher fare classes upon request. The higher Medallion Status you have, the more likely you are to get upgraded.

What is Delta One?

You’ll find Delta One fares on select long-haul flights. You can lay your seat flat in your own cabin, eat meals curated by Delta’s chefs and enjoy complimentary wine, beer and spirits.

Preferred Seating and priority waitlist status round out Medallion flight benefits.

Fee waivers

Medallion fee waivers can be valuable since Delta charges sizable fees for some transactions.

Airport benefits

Get on your flight faster.

SkyTeam benefits

SkyTeam is a worldwide airline alliance with 20 members, including Delta. After earning miles in the network, you can use them for flights on member carriers.

Hertz car rental benefits

Medallion Members earn more Delta SkyMiles for eligible Hertz rentals.

Gold, Platinum and Diamond Medallion Members get automatic status in the Hertz Gold program.

Delta Vacations

Through Delta Vacations, you can bundle services like hotels, flights and car rentals. Delta offers discounts based on how much you spend.
