China Eastern Airlines (CEA) has set a new benchmark in aviation with the launch of its world-record-breaking flight route connecting China, New Zealand, and Argentina. The inaugural flight, which took place on December 4, 2025, is already being hailed as the world’s longest one-stop scheduled passenger service, offering a unique travel experience across three continents.

This new service, operated under flight numbers MU745 and MU746, makes a significant leap in connecting Asia, Oceania, and South America with direct flights that had previously been unthinkable. Covering nearly 20,000 kilometers (approximately 12,400 miles), the flight offers a crucial link for both travelers and businesses, positioning China Eastern Airlines as a major player in global connectivity.

What is the New Flight Route?

The newly launched Shanghai–Auckland–Buenos Aires route spans three major cities on different continents. The flight departs from Shanghai’s Pudong Airport (PVG) and makes a technical stop in Auckland (AKL), New Zealand, before continuing on to Buenos Aires (EZE), Argentina. Although the flight makes a stop in Auckland, it remains classified as a “direct” flight due to the same aircraft and flight number continuing the journey.

This direct route, which operates twice weekly on Mondays and Thursdays, is designed with long-haul travelers in mind, particularly those flying from China to Argentina. The technical stop in Auckland is essential for refueling and crew change, ensuring the Boeing 777-300ER, with its large fuel capacity and cargo hold, is equipped to handle the immense distance.

Where is This New Flight Going?

This flight route is not only pioneering in terms of distance but also fills a critical gap in global air travel. The addition of Auckland to the route restores a previously discontinued air connection between New Zealand and Argentina. The flight now serves as the only direct connection between China and Argentina, with no previous single-aircraft service offering this link.

For New Zealand, the route re-establishes a much-needed connection with South America, specifically Buenos Aires. For Argentina, it strengthens the relationship with China, ensuring that Argentine products such as beef and wine have faster access to the Chinese market, while Chinese exports, particularly in technology and electronics, can flow directly into South America.

Why is This Flight Important?

This new route is much more than just a record-breaking achievement. It plays a key role in the global trade network, particularly in high-value industries. With the Boeing 777-300ER at the helm, the aircraft’s extensive cargo capacity enables China Eastern Airlines to facilitate the faster movement of goods across the Southern Hemisphere. Cargo shipments of goods like New Zealand wine, Argentine beef, and Chinese electronics will now move more efficiently between continents.

In addition, the route brings significant benefits to regional competition. As China Eastern Airlines now holds Fifth Freedom Rights for the Auckland-Buenos Aires segment, the airline can transport passengers and cargo between these two cities. This provision opens up new travel and trade options for both countries, enhancing local economies and increasing travel choices for passengers.

How Does This Impact Travelers?

The convenience and speed of the new route are poised to make a substantial impact on travelers looking for more direct flights between these regions. Before this new route, passengers from Shanghai to Buenos Aires had to navigate multiple connections in Europe, the Middle East, or North America, extending their travel time significantly. With the Shanghai-Auckland-Buenos Aires direct flight, the travel time is notably shorter, offering a more convenient and time-efficient option for passengers.

Additionally, the route has been made more accessible for Chinese nationals. Following a policy change by the New Zealand government that eased transit visa requirements, travelers can now transit through Auckland without the previous visa complications, simplifying the long 29-hour journey.

When is the Route Operational?

The Shanghai-Auckland-Buenos Aires route operates twice a week, with flights departing from Shanghai every Monday and Thursday. The inaugural flight took place on December 4, 2025, and the schedule is set to provide consistent connectivity between these key global hubs.

How Does This Affect Global Trade?

The introduction of the Southern Corridor through this new flight opens an important trade lane. The direct air connection between China and Argentina is poised to revolutionize the movement of goods such as electronics, technology, and consumer goods from China to South America. Likewise, goods from Argentina, such as premium beef, wine, and agricultural products, can now reach Chinese consumers in record time.

This route also enhances the Auckland-Buenos Aires corridor, providing a vital alternative for the transportation of goods and boosting the competitiveness of regional trade between New Zealand and Argentina.

Conclusion

In conclusion, China Eastern Airlines has successfully bridged continents with the launch of the Shanghai-Auckland-Buenos Aires route. This groundbreaking service, which holds the title of the world’s longest one-stop scheduled flight, is not only a triumph for the airline but a significant achievement for the aviation industry. The improved connectivity promises to boost trade, simplify travel, and promote stronger economic ties between China, New Zealand, and Argentina.
