Delta Partner Airlines: The Global Network Behind SkyMiles Value

Delta Air Lines has an extensive global network that allows SkyMiles members to earn and redeem miles even when they aren’t flying on Delta flights. This is one of the program’s greatest practical benefits: your travel options extend far beyond Delta’s own flights. Delta is a founding member of the SkyTeam alliance, and over time, it has also moved beyond the standard alliance model by forging closer partnerships and investing in airlines in key regions, creating an even broader and more strategically valuable roster of Delta partner airlines.

That’s why it’s important to understand Delta’s partner network. Some partners are part of SkyTeam; others are closer strategic or joint-venture partners; and others operate as codeshare partners, further expanding Delta’s reach. In this guide, we’ll take a detailed look at Delta’s partner airlines, their place in the broader network, and their importance for earning, redeeming, and maximizing SkyMiles at every status level.

Delta’s Alliance & SkyTeam

The SkyTeam alliance currently includes airlines such as Air France, KLM, Korean Air, Aeromexico, Virgin Atlantic, SAS, Saudia, Vietnam Airlines, and several others. For SkyMiles members, this means they can earn miles, redeem them, and enjoy certain elite benefits when flying with these airlines.

However, not all of Delta’s partnerships are created equal. Some airlines are simply part of the same alliance, while others have much deeper commercial ties with Delta through joint ventures or long-term strategic partnerships. That’s why travelers should view Delta’s partner map in several tiers: first, the broader SkyTeam alliance; then a smaller group of particularly important partners that carry more weight for route planning, reciprocal benefits, and overall SkyMiles value. Once you understand this structure, the rest of Delta’s partner network becomes much easier to use strategically. If you’d like, I can also rewrite the next section on major global airline partners in the same style so that the entire article reads consistently.

Delta’s Core Global Airline Partners

Delta specifically highlights a smaller group called Core Global Airline Partners. Delta currently lists these as:

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

This is the most important tier in the real-world Delta ecosystem. Delta says these partners offer enhanced reciprocal benefits, and with select partners, they can also be relevant for higher-end benefits such as Global Upgrade Certificate redemption. In other words, if you are a Delta loyalist trying to understand which relationships have the deepest value, this is the group to focus on first. 

These are also the partner airlines that tend to matter most for travelers chasing status or trying to get the most out of Medallion benefits. If that is your angle, this article pairs naturally with your guides on MQDs, Delta status levels, and the Delta status match challenge.

Delta’s Global Airline Partners

Beyond the core group, Delta also lists a larger set of Global Airline Partners.

• Aerolíneas Argentinas
• Air Europa
• China Airlines
• EL AL Israel Airlines
• Garuda Indonesia
• Kenya Airways
• MEA
• Saudia Airlines
• Scandinavian Airlines
• TAROM
• Vietnam Airlines
• WestJet
• Xiamen Airlines. 

The list of partners is subject to change.

Delta Code Share Partners

Delta’s codeshare partners form a wider network than the core loyalty map. Delta’s agency resource explains that codesharing allows Delta to sell flights under the “DL” code on partner-operated services, giving customers access to more destinations and more connection options. 

The current Delta codeshare list includes airlines such as:

• Aerolíneas Argentinas
• Aeromexico
• Air Europa
• Air France
• China Airlines
• China Eastern
• airBaltic
• China Southern and others, depending on the market and sales channel. 

A codeshare partner is not necessarily one of Delta’s closest strategic partners, and it may not come with the same reciprocal elite treatment, lounge rules, or upgrade opportunities. Codeshare relationships are often about booking convenience and network expansion, not always deeper loyalty integration. 

The Most Important Delta Partners by Region

Europe

For Europe, the most important Delta partners are usually Air France, KLM, and Virgin Atlantic. Delta’s official airline-partners page highlights Virgin Atlantic in the transatlantic section, and Delta’s benefits page treats Air France, KLM, and Virgin Atlantic as key partners with stronger integration than the average partner relationship. 

For many U.S.-based travelers, these are the partner airlines that matter most for premium-cabin redemptions, SkyTeam lounge access, and smoother transatlantic connections.

Asia

For Asia, the most important Delta partner is usually Korean Air, with China Eastern also playing a major role. Delta says its joint venture with Korean Air offers an expanded U.S.-Asia network, and Delta also continues to highlight China Eastern among its core global partners. 

If your travel is Asia-heavy, this is one of the clearest examples of how a “core partner” can matter more than a generic alliance label.

Latin America and Canada

For the Americas, Delta’s partner page highlights Aeromexico, LATAM, and WestJet. Delta specifically presents these as important relationships for Mexico, South America, and Canada. LATAM is especially notable because it shows that Delta’s most useful partnerships are not limited to its formal alliance membership. 

Why Delta Partners Matter for Status and Benefits

Delta’s partner-benefits page says Medallion members can receive recognition such as priority boarding, preferred seats, and baggage benefits when flying with eligible partners, and partner-marketed flights can also earn MQDs based on distance and fare class. That means partner choice can directly affect how quickly you earn status and how much value you get once you have it. 

This becomes even more important as you move up the Medallion ladder. Readers focused on elite strategy may want to continue with your guides to Delta Silver, Delta Gold Medallion, Delta Platinum Medallion, Delta Choice Benefits, Delta Million Miler, and even Delta 360 for the ultra-high-spend end of the spectrum.

Lounge Access and SkyTeam Benefits

Partner airlines also play a role in lounge access. SkyTeam Elite Plus members (Gold, Platinum, and Diamond Medallion members) can access SkyTeam lounges provided they are traveling on an international SkyTeam flight on the same day, in accordance with the alliance’s standard rules.

Delta notes that lounge access is not available when traveling to the Caribbean, regardless of Medallion tier or purchased class of service. 

Bottom Line

Delta’s partner network is best understood as a layered system, not a flat list. First comes SkyTeam, which is Delta’s formal alliance. Then comes Delta’s smaller group of Core Global Airline Partners, which are usually the most valuable for serious Delta flyers. Then comes the broader set of Global Airline Partners, and finally the wider circle of codeshare partners that expand Delta’s network reach. 

For most travelers, the partner airlines that matter most are still Air France, KLM, Virgin Atlantic, Korean Air, Aeromexico, LATAM, and WestJet, because those are the relationships that tend to shape real booking choices, elite recognition, and transatlantic or transpacific strategy. 

The smartest way to use Delta’s ecosystem is not to memorize every partner name. It is to understand which partners are core, which ones are broader alliance or global partners, and which ones are simply codeshare tools that help build a better itinerary.
