China Southern vs China Eastern: Which Should You Fly? (2026)

China Southern and China Eastern are two of China's "big three" airlines, and on paper they look almost interchangeable: both are massive full-service carriers with modern fleets, lie-flat business class on newer jets, and similar prices. But there is one difference that trips up a lot of foreign travelers, and it can quietly cost you a chunk of frequent flyer miles if you book the wrong one.

This guide breaks down the real, practical differences: where each airline is based, which alliance (if any) it belongs to, how the fleets and service compare, and exactly which one you should book for your trip.

Quick Comparison

Factor	China Southern (CZ)	China Eastern (MU)
Primary hub	Guangzhou (CAN)	Shanghai (PVG / SHA)
Secondary hub	Beijing Daxing (PKX)	Shanghai (dual airport)
Alliance	None (left SkyTeam Jan 1, 2020)	SkyTeam
Fleet size	~700+ aircraft (Asia's largest)	Large, modernized
Network strength	South China, SE Asia, Australia/Oceania	Trans-Pacific (US West Coast), intra-Asia
Loyalty program	Sky Pearl Club	Eastern Miles
Fleet age	~9-10 years average	Newer on many routes

If you only remember one thing from this table: China Southern is no longer in SkyTeam, and China Eastern still is. That single fact drives most booking decisions for anyone who collects miles.

The Surprise: China Southern Is NOT SkyTeam Anymore

This is the biggest source of confusion, and even some travel articles still get it wrong.

China Southern left the SkyTeam alliance on January 1, 2020. Today it is not a member of any of the three global alliances — not SkyTeam, not Star Alliance, and not oneworld. It now operates entirely on its own, running its own Sky Pearl Club loyalty program and forming bilateral codeshare partnerships with individual carriers rather than relying on an alliance umbrella.

What this means for you in plain terms:

• You can no longer assume your SkyTeam miles credit on China Southern. If you fly Delta, Air France-KLM, or Korean Air and want those miles to count, China Southern is no longer an automatic fit. China Eastern is.
• China Southern still partners with plenty of airlines — just bilaterally, through direct codeshare and frequent flyer agreements rather than the alliance. So earning or redeeming may still be possible with certain partners.
• You must check the current partner list before you book if miles matter to you. Do not rely on old "China Southern is SkyTeam" advice; it has been wrong since 2020.

China Eastern, by contrast, remains a full SkyTeam member. So if your loyalty lives in the SkyTeam ecosystem, the math is simple: China Eastern keeps your miles in the family, and China Southern requires you to double-check.

China Southern (CZ)

Overview

China Southern is the giant of Chinese aviation. With roughly 700-plus aircraft, it is Asia's largest airline by fleet size — bigger than China Eastern, bigger than Air China, bigger than any other carrier on the continent. It is headquartered and hubbed in Guangzhou, the commercial heart of South China, with a growing secondary hub at Beijing's newer Daxing airport.

Strengths:

• Guangzhou (CAN) hub — the gateway to South China and the Pearl River Delta
• Asia's largest fleet, meaning frequent flights and lots of route options
• Excellent coverage of Southeast Asia and Australia/Oceania
• Modern fleet with widebodies including the Airbus A350, A330, and Boeing 777-300ER
• Often praised for catering (Cantonese-style menus) and attentive crew, especially domestically

Weaknesses:

• No alliance membership — miles are not guaranteed to transfer
• Less convenient if your destination is Shanghai or the US West Coast
• Service is solid but does not reach top-tier Asian-carrier standards

Network

China Southern's network is built around the south. From Guangzhou it offers some of the densest service to Southeast Asia of any Chinese carrier, and it is one of the strongest options for routes to Australia and the broader Oceania region. Its Beijing Daxing hub adds northern reach, and it covers domestic China comprehensively given the sheer size of its fleet.

Fleet

The fleet is genuinely modern — averaging roughly 9 to 10 years old. Long-haul and premium routes are flown on widebodies like the A350, A330, and 777-300ER. On some domestic routes you may even fly Chinese-built aircraft such as the C919 or ARJ21, which is becoming more common across the major Chinese carriers.

Best For

• Flying into or out of Guangzhou and South China
• Travel to Southeast Asia, Australia, or Oceania
• Travelers who value catering and cabin service on domestic flights
• Anyone who does not depend on SkyTeam miles

China Eastern (MU)

Overview

China Eastern is based in Shanghai and operates out of both of the city's airports: Pudong International (PVG) for most long-haul flights and Hongqiao (SHA) for domestic and regional service. Shanghai is China's financial capital, which makes China Eastern the natural choice for business travel into eastern China. Crucially, it remains a SkyTeam member.

Strengths:

• Shanghai hub (dual-airport: PVG and SHA) — China's business gateway
• SkyTeam member — earn and redeem with Delta SkyMiles, Air France-KLM Flying Blue, Korean Air, and other partners
• Strong trans-Pacific network, especially to the US West Coast
• Newer aircraft on many routes
• Broad intra-Asia coverage

Weaknesses:

• Less useful if you are headed to South China or Australia
• Shanghai's airports are busy and can be congested
• Service is comparable to China Southern, not noticeably better

Network

China Eastern's strength is the Pacific. It runs a large trans-Pacific operation focused on the US West Coast, plus extensive intra-Asia routes from its Shanghai base. If your trip routes through Shanghai or connects from North America, China Eastern is frequently the more convenient and better-connected option.

Best For

• Flying into or out of Shanghai and eastern China
• SkyTeam loyalists who want miles to count
• US West Coast to China connections
• Anyone who wants to keep earning Delta, Flying Blue, or Korean Air miles

Head-to-Head

Hub & Routes

This is the first thing to check, and often the deciding factor.

• Guangzhou / South China, or onward to Australia or Southeast Asia → China Southern is the natural fit.
• Shanghai, or connecting to/from the US West Coast → China Eastern wins on convenience and network depth.

Geography usually answers the question before alliance or service ever comes into play. Pick the airline whose hub matches your itinerary.

Alliance & Miles

This is the single biggest practical difference between the two airlines.

• China Eastern (SkyTeam) is the clear winner if you credit miles to Delta, Air France-KLM Flying Blue, Korean Air, or any other SkyTeam program. Earning and redeeming is straightforward.
• China Southern is alliance-free. Since it left SkyTeam in 2020, you cannot assume your miles will transfer. It does maintain bilateral codeshare and frequent flyer partnerships, so check its current partner list before booking if miles matter.

If you have no loyalty allegiance and do not chase miles, this factor drops out entirely — and you can decide on price and schedule instead. For more on how the alliance picture plays out across the big three, see our China Eastern vs Air China comparison.

Fleet & Service

Both airlines have modernized heavily, and the gap here is modest.

• China Southern is the largest carrier in Asia and is frequently singled out for its catering (Cantonese-style menus) and crew, especially on domestic routes. Its fleet averages roughly 9-10 years.
• China Eastern is competitive, flying newer jets on many of its routes with comparable cabins and amenities.

Realistically, the difference is small. Both offer lie-flat business class on their newer widebodies, meals on long flights, English announcements, and seatback entertainment on international routes. Neither matches the experience of top-tier Asian carriers like Singapore Airlines or Cathay Pacific — but both are perfectly comfortable. If you specifically care about the premium cabin, our Air China vs China Eastern business class breakdown digs into seats, lounges, and catering in detail.

Price & Schedule

On comparable routes, fares are generally similar. Because the fleet-and-service difference is modest and price tends to be close, schedule and ticket price often end up being the real tiebreaker once you have settled the hub question. Always compare both airlines on your specific dates rather than assuming one is consistently cheaper.

Domestic Flights

For flying within China, either airline is a fine choice. Both have enormous domestic networks (China Southern's is the largest in the country by fleet), prices are similar, and service quality is close. For domestic legs, do not overthink it — pick by hub convenience, schedule, and price. China Southern's catering reputation is a mild plus on domestic routes, but it is not decisive.

Safety

Both China Southern and China Eastern maintain strong, modern safety records and hold full international certifications. Safety is not a meaningful differentiator between them — you can choose based on hub, miles, schedule, and price with confidence. Both are equipped and certified to international standards, and both operate young, well-maintained fleets.

Which to Choose?

Choose China Southern If:

• You are flying into or out of Guangzhou or South China
• Your destination is Australia, Oceania, or Southeast Asia
• You value catering and cabin service, particularly on domestic flights
• You do not rely on SkyTeam miles (or you have confirmed China Southern's current partners cover your program)

Choose China Eastern If:

• You are flying into or out of Shanghai
• You collect SkyTeam miles (Delta, Flying Blue, Korean Air, etc.) and want them to count
• You are connecting to or from the US West Coast
• Eastern China is your focus

It Doesn't Matter Much If:

• Neither Guangzhou nor Shanghai is your hub
• You do not collect frequent flyer miles
• Price and schedule are your top priorities
• You are flexible on routing — in that case, just book the cheaper or more convenient option

How to Book

For both airlines, the easiest place to compare fares and book is Trip.com (formerly Ctrip), which handles Chinese carriers smoothly and shows English-language schedules and prices side by side. Booking directly with the airlines is also possible, but Trip.com makes it easy to compare China Southern and China Eastern on the same route at once.

For domestic flights specifically, either airline works well — choose by hub, schedule, and price rather than by brand. If you are new to booking Chinese carriers, our booking on Trip.com/Ctrip guide walks through the process step by step, including payment methods and what to expect at the airport.
