How to earn Delta SkyMiles with partners

You can earn miles toward Delta’s loyalty program when you fly with one of its partner airlines. However, the way you accrue miles can vary depending on the specific partner.

Take, for example, Air France — which is one of Delta’s core global partners. When you book an Air France flight, you’ll earn miles based on the number of miles you fly multiplied by a percentage designated to the fare class you book. These percentages can also change depending on whether you’re flying only in Europe or to other international destinations.

So, if you fly from Paris to London with Air France on an economy fare ticket, you’ll earn 100 percent of the miles you actually fly. On a business class ticket, you’ll earn a boosted 200 percent of the total miles in SkyMiles.

Delta’s website offers an in-depth look at different earning rates with each of its partners.

How to use Delta SkyMiles with partners

The best way to redeem your Delta SkyMiles with a partner airline is by booking an award flight serviced by the partner.

You can do this by finding the flight you want to book on Delta’s website or mobile app. When you search for your destination and preferred dates, you can toggle between showing the fares in dollars or in SkyMiles. Depending on how many miles you have in your account, you may also choose to book with a combination of miles and cash.

Some of Delta’s partners may not be available to book online, though these partners can vary. If that’s the case with a partner airline you’d like to book with, you can contact Delta Reservations by phone to learn more about your options.

Partner status transfer

You’ll also get to maintain some status benefits with partner airlines if you’re a Delta Medallion member. These benefits vary depending on your Medallion status and the specific airline. Some partner airlines don’t offer all Medallion benefits, for example, and Delta’s core global airlines may offer extended benefits over other global airline partners.

If maintaining the perks of your Medallion status is important to you when flying with partners, make sure you read all the details of what you can expect with each partner airline before you book.

You can find more information on Medallion benefits with partners on Delta’s website.

How to maximize Delta SkyMiles

If you fly often and prefer flying with Delta, maximizing the number of SkyMiles you earn can be a great way to save on your annual travel costs and enjoy some great benefits when you fly.

Here are a few more ways to maximize how you earn and redeem your Delta SkyMiles:

Shop with partners

Delta’s non-airline partners can offer valuable boosts to your miles.

If you already have a Starbucks account, for example, you can like your SkyMiles account and earn 1 mile per dollar you spend at participating Starbucks. Your Starbucks rewards will benefit, too, with double stars earned on days that you fly with Delta.

While these rewards may not add up as quickly as flights, they can help you earn more miles over time. Check Delta’s SkyMiles partner offers regularly to make sure you’re taking advantage of the offers that fit with your regular spending.

Use the right credit card

A co-branded Delta credit card like the ones above is a great way to boost your SkyMiles earnings.

You may also choose to use a credit card that earns rewards points which you can transfer to Delta. Points you earn under the American Express Membership Rewards program, for example, are transferable with Delta SkyMiles at a 1:1 ratio.

You can use a card that best aligns with your budget and spending habits to maximize the number of SkyMiles you earn toward future travel with Delta.

Be flexible with redemptions

Award flights are one of the best ways to use your SkyMiles, but you can get more value for your miles with flexible dates.

Delta offers dynamic pricing that changes depending on your route, your dates and when you book. Before you book your award travel, play around with the booking tool on Delta’s website or app to get a feel for how prices change over the days surrounding your trip.

The bottom line

Delta Air Lines has a vast list of more than 20 worldwide partners, offering you the option to travel nearly anywhere in the world using your SkyMiles.

If you like flying Delta, maximizing your SkyMiles earned can help you more quickly access free award flights, upgrades, travel perks and more. And when you’re ready to book, take the time to research your best option to ensure you’re getting the best redemption value possible.
