SkyMiles is the frequent flyer program of Delta Air Lines, a member of the global SkyTeam Alliance. Of course, Delta is also one of the world’s largest airlines. Beyond booking Delta flights, SkyMiles can be used on a range of partner airlines that aren’t easily accessible through other programs.

While opportunities for Australians to earn SkyMiles can be limited, it’s not an impossible task. This guide looks at how it’s done, and how to make SkyMiles work for you.

How do I join Delta SkyMiles?

Signing up to the SkyMiles loyalty program is free. You can sign up using this link, following these steps:

  1. Go to the SkyMiles enrolment page.
  2. Enter your name and other personal details.
  3. Create your login info including password and security questions.
  4. Click ‘complete’ to finalise your registration.

Upon joining, you’ll be provided with your unique SkyMiles membership number. You should receive an email with that number, but it’s always best to make a note of it anyway. You may also wish to download and set up the Delta mobile app for Android or iOS, to keep that SkyMiles account at your fingertips.

How do I earn SkyMiles?

Delta SkyMiles can be earned across a wide variety of partners, though most are based in the US. You’ll earn 5-11 miles per US$1 spent on Delta-marketed flights.

Closer to home, you could earn miles by flying on Delta’s many partners. Among them, China Airlines, China Eastern, China Southern, Garuda Indonesia, Hawaiian Airlines, Korean Air, LATAM Airlines, Vietnam Airlines and XiamenAir. Browse Delta’s full list of partner airlines here.

While you can buy SkyMiles, the rates are usually quite expensive and there aren’t too many promotions. SkyMiles don’t expire, which is a strong positive. Not many programs offer that.

How do I use SkyMiles?

Like any other frequent flyer program, SkyMiles usually give you the best return when used on flights. That’s particularly true of premium cabin reward seats on international flights. However, Delta no longer publishes an award chart, even for partner airlines.

This means the number of miles needed for any given flight can change at any time.

Here are some of the indicative rates for flights from Australia to various destinations, but note that prices are dynamic and can change at any time:

SkyMiles for one-way travel from SydneyEconomyPremium EconomyBusiness
To UK/Europe (e.g. with Taiwan’s China Airlines)60,00090,000
To the US (e.g. with Delta)82,000+170,000+225,000+
to Asia (e.g. with Vietnam Airlines)40,00070,000-75,000

As you can see, rates when booking on Delta can be a little more unpredictable. They tend to swing up and down in line with cash fare prices. On the other hand, rates for booking on partner airlines are still dynamic but don’t tend to fluctuate as much.

It’s fair to say that booking partner airlines may often present better value on international flights than by flying with Delta!

That’s especially true if you can nab Business all the way to Europe for just 90,000 SkyMiles. That’s only 8,000 miles more than some of the Sydney-LAX flights we found in Economy Class… But for upwards of 24 hours of Business Class flying.

If Delta does fit with your plans though, US domestic flights can be another great way to spend your SkyMiles. When booking far enough in advance, flights in Economy can start at just 4,500 SkyMiles. That’s for a Basic Economy booking – but even standard Economy can be grabbed for just 6,000 SkyMiles.

Better yet, you only need to pay US$6 on the side with these bookings to cover the taxes and fees.

Of course, don’t forget to check how much it costs to buy the same seat on the same flight, to make sure you’re getting the best value.

How do I earn Delta SkyMiles status?

Delta SkyMiles has four public status levels above the basic membership: Silver, Gold, Platinum and Diamond Medallion.

These tiers are earned with a mix of Medallion Qualifying Dollars (MQD, for US-based members only), along with either Medallion Qualifying Miles (MQM) or Medallion Qualifying Segments (MQS).

SkyTeam Elite benefits apply to the Silver Medallion level, while the better SkyTeam Elite Plus benefits with lounge access kick in with Gold Medallion status and higher.

Delta is currently offering a status match to its Silver, Gold and Platinum tiers. Travellers with similar status in Qantas Frequent Flyer, Velocity Frequent Flyer and more are welcome to apply.

How do I contact Delta SkyMiles?

To get in touch with Delta SkyMiles about a membership enquiry or flight redemption, try:

  • Sending them a direct message on Twitter or Facebook.

While the call centre might be the quickest way to resolve your issue, try the social media channels if the line is busy or you cannot easily call overseas numbers.

Summing up

Delta SkyMiles is a massive frequent flyer program with a similarly sizeable home airline attached. The ability to earn and spend points across SkyTeam and beyond makes it a drawcard for savvy travellers.

When it comes to using SkyMiles, there are some tremendously good-value redemptions such as Australia to Europe for 90,000 miles in Business Class. On the flip side, Delta’s own flights are subject to dynamic pricing, which can really blow the numbers out of the water.
