Delta elite status is expensive. In order to become a top tier Diamond Medallion, you need to earn $15,000 Medallion Qualification Dollars. This will go up to $20,000 for the next status year.

If you spend $15,000 on Delta Air Lines this year, you'll be able to keep your Diamond Diamond status. You can earn 15,000 MQDs if you maximize your earnings on Delta's partners.

SkyTeam members can earn MQDs with any SkyMiles member. Depending on how long the fight is, a $1,000 long-haul business class ticket booked directly with KLM could accumulate up to 2,000 MQDs.

If you earn MQDs on partner flights, you can earn Delta's elite status much less expensive.

Some background on earning MQDs with partners

ZACH GRIFF/THE POINTS GUY

Delta mostly gives elite status to members with high annual spending, at least when you earn status on Delta's own flights. If you are eligible for the MQD waiver through credit card spending, you will be able to get status on Delta-ticketed flights, but you will need Medallion Dollars to do so.

You get 1 MQD for every dollar spent on Delta flights. On a Delta flight from John F. Kennedy International Airport to Los Angeles International Airport, you would make 311 MQDs. You can find this information during the booking process on Delta.com.

Delta.com is a website.

Whether or not you book your ticket with Delta directly, the length of your flight, the fare class and the airline that operates your flight are some of the factors that can affect your MQD.

1. Should you book your ticket with Delta directly?

If you book a ticket with Delta, you will earn MQDs based on your ticket price. If you book an Air France ticket on Delta.com, you'll still get MQDs based on the ticket's price.

When you book a ticket with a partner airline, you will be able to earn MQDs based on the distance you travel and the partner rate.

There is a business class flight from Seattle-Tacoma International Airport to Paris-Charles de Gaulle Airport. The flight is the same price when booking with both airlines.

During the booking process on Delta.com, the earnings are shown. You would earn 3,500 MQDs if you booked this ticket with Delta.

DELTA.COM

When booking a ticket with Air France, Delta earnings will need to be looked at. Air France flights in the Z and I fare class earn 40% of their SkyMiles on a 40% basis.

DELTA.COM

To calculate how many MQDs you would make, we have to take the total flight distance and divide it by 40.

10,033 miles is equal to 4,013.20. If you booked with Air France, you would make 4,013 MQDs.

GCMAP.COM

Booking your ticket with Air France would earn you more MQDs.

2. Which are the best partner airlines for earning MQDs?

Delta gives the earning rates for all of its airline partners. There are two types of Global Airline Partners. Core airlines earn more frequent flyer points.

Delta's core global airline partners are listed.

  • Aeromexico.
  • Air France.
  • China Eastern Airlines.
  • KLM.
  • Korean Airlines.
  • LATAM.
  • Virgin Atlantic.

The Global Airline Partners that earn MQDs are not core to Delta.

  • Aerolineas Argentinas.
  • Air Europa.
  • Cape Air.
  • China Airlines.
  • China Southern Airlines.
  • CZA (Czech Airlines).
  • Guarda Indonesia.

  • ITA Airways.
  • Kenya Airways.
  • MEA (Middle Eastern Airlines).
  • Saudia.
  • TAROM.
  • Vietnam Airlines.
  • WestJet.
  • Xiamen Airlines.

3. How do you see what fare class you’re booked in?

It can be hard to tell what class you are booking. I had to call Air France to find out what class the flight would be in.

Some airlines will let you know about your class online. Next to your class of service, Virgin Atlantic will show your fare class.

VIRGINATLANTIC.COM

On the checkout screen, you can see what class you are booking in. On the Korean Airlines business-class flight from Daniel K. Inouye International Airport (HNL) to Incheon International Airport (ICN), I was able to select "show details" on the website. If you're booking an itinerary with multiple airlines, you should still confirm the ticketing airline with the website.

Bottom line

If you travel in one of the examples, you can earn more than on Delta flights. You can earn SkyMiles on partner flights even if you start from scratch.

You can sometimes earn north of 3.5 MQDs per dollar spent, so if you spend just over $4,000 you can earn 15,000 MQDs. You would need to spend $15,000 on Delta flights to get 15000 MQDs.
