In a landmark move that underscores the growing interconnectivity of global air travel, China Eastern Airlines has announced the launch of the world’s longest one-stop commercial route. Beginning December 2025, the airline will operate a new long-haul service connecting Shanghai Pudong International Airport (PVG) with Buenos Aires Ezeiza International Airport (EZE), featuring a strategic layover at Auckland Airport (AKL), New Zealand.
Spanning approximately 19,700 kilometers (12,229 miles), this ambitious route is poised to surpass the previous record held by Air China’s Beijing–Madrid–São Paulo service. The new connection is set to operate twice weekly, offering travelers a unique and efficient bridge between East Asia and South America.
Premium Comfort with the Boeing 777-300ER
China Eastern will deploy its state-of-the-art Boeing 777-300ER aircraft for this ultra-long-haul service. Equipped with a tri-class configuration, the aircraft features six luxurious First Class suites, 52 Business Class seats, and 258 spacious Economy Class seats. Designed for endurance and efficiency, the 777-300ER ensures optimal passenger comfort on journeys exceeding 15 hours of air time.
This aircraft’s extended range and advanced fuel efficiency make it ideal for the Shanghai–Auckland–Buenos Aires route, providing passengers with a seamless flying experience even across three continents.
Auckland Strengthens Global Hub Status
Inclusion of Auckland as a transit point reinforces New Zealand’s growing role in international aviation. Auckland Airport, a leading South Pacific hub, is expected to benefit from increased passenger traffic and elevated global profile. The stopover will facilitate onward travel to Australia, the Pacific Islands, and New Zealand’s domestic destinations.
With efficient terminal operations and expanding international connections, Auckland stands to gain economically and strategically, acting as a bridge between Asia and Latin America.
Boost to China–Argentina Bilateral Tourism and Trade
For Argentina, the new direct flight marks a breakthrough in international connectivity. It opens doors for thousands of Chinese tourists to explore Argentina’s vast landscapes—from the tango-filled streets of Buenos Aires to the rugged terrain of Patagonia and the wine valleys of Mendoza.
Tourism officials in Argentina project a sharp increase in Chinese arrivals, which reached 80,000 visitors in 2019. With the introduction of this new route, that number could surpass 100,000 by 2026, injecting millions into the Argentine economy through travel spending.
Furthermore, this enhanced connectivity is expected to strengthen China–Argentina trade relations, especially in agriculture, lithium, and energy sectors. Direct cargo movement between Shanghai and Buenos Aires will help streamline logistics for businesses across both nations.
New Zealand Simplifies Transit with NZeTA
Coinciding with the route’s launch, New Zealand will implement a visa reform beginning November 2025. Chinese travelers transiting through Auckland will no longer require a traditional transit visa. Instead, they can apply for a New Zealand Electronic Travel Authority (NZeTA), expediting their travel and reducing paperwork.
This policy supports Auckland’s ambitions to be a top-tier transit hub and encourages more Chinese travelers to explore stopover tourism opportunities in New Zealand. The simplified entry process is also likely to benefit New Zealand’s own tourism sector, which continues to recover post-pandemic.
Part of China’s Belt and Road Aviation Expansion
This new route aligns with China’s Belt and Road Initiative (BRI), which seeks to enhance global connectivity and economic cooperation. By expanding its aviation network to South America, China Eastern Airlines reinforces China’s presence in the Western Hemisphere.
The route not only symbolizes growing diplomatic and economic ties between China and Argentina but also serves as a strategic aviation link in the broader BRI framework. With Argentina actively seeking Chinese investment in infrastructure and technology, the flight could play a vital role in fostering bilateral partnerships.
Future of Long-Haul Travel Redefined
The Shanghai–Auckland–Buenos Aires flight represents more than just a new route—it signals a transformation in how the world connects. Travelers will now have more efficient access between East Asia and South America, a corridor historically underserved by direct flights.
With premium service offerings, transit-friendly policies, and strong geopolitical alignment, the new route is expected to become a preferred option for both business and leisure travelers. Aviation experts anticipate that this model—ultra-long-haul flights with strategic one-stop layovers—could shape the future of global air travel.
Conclusion: A Milestone in Global Connectivity
China Eastern Airlines’ upcoming Shanghai–Auckland–Buenos Aires route stands as a milestone in international aviation. It is not only the longest one-stop flight but also a testament to growing global collaboration across Asia, Oceania, and South America.
With enhanced comfort, streamlined transit options, and expanded trade and tourism opportunities, this new service promises to revolutionize intercontinental travel. As countries look to rebuild their tourism and trade sectors, this ambitious new route exemplifies the future of global connectivity—faster, farther, and more inclusive.
