Buckle up for a marathon in the sky. A new aviation titan has arrived, shattering distance records with a staggering journey that spans hemispheres. China Eastern Airlines has officially launched a flight that keeps passengers on board for over a full day and night. This new route promises to change how we connect the far corners of the globe, but it comes with a serious test of endurance.
Breaking Down the Marathon Route
The aviation world is buzzing about flight MU745. This service connects Shanghai, China to Buenos Aires, Argentina. It is a massive undertaking that covers roughly 12,000 miles of the Earth’s surface.
Travelers will spend approximately 29 hours on this journey. This duration includes a brief stopover, but it is sold as a single direct connection.
This flight cuts the travel time between China and South America by more than four hours.
Previously, travelers had to rely on multiple layovers in Europe, the Middle East, or North America. Those routes often pushed total travel time well over 30 hours or even 40 hours. This new direct option streamlines the process significantly for business travelers and tourists alike.
The route utilizes a unique path known as the “southern corridor.”
Most flights between these regions typically fly north over Russia and Europe. However, MU745 heads south to New Zealand before pivoting toward South America. It crosses both the Northern and Southern Hemispheres, as well as the Eastern and Western Hemispheres.
Here is a quick look at the staggering numbers behind this flight:
- Origin: Shanghai Pudong International Airport (PVG)
- Destination: Ministro Pistarini International Airport (EZE)
- Stopover: Auckland Airport (AKL)
- Total Distance: Over 19,000 kilometers (approx. 12,000 miles)
- Frequency: Twice weekly

Inside the Boeing 777 Experience
China Eastern Airlines is deploying the Boeing 777-300ER for this ultra-long-haul service. This wide-body aircraft is a workhorse of international aviation known for its reliability and range.
It is designed to handle the grueling demands of intercontinental travel.
Passengers in economy class will face the biggest challenge of staying comfortable for 29 hours.
The aircraft features a three-class configuration to suit different budgets. There are six lavish first-class suites for those who want total privacy. The business class cabin holds 52 lie-flat seats which are essential for sleeping on such a long trip.
The economy cabin accommodates 258 passengers. While modern seats have improved, sitting upright for more than a day is physically demanding.
Health experts often warn about Deep Vein Thrombosis (DVT) on flights longer than four hours. Passengers on MU745 will need to be proactive about stretching and hydration.
“For a flight of this magnitude, the seat you choose isn’t just a luxury; it is a health decision,” notes aviation analyst Sarah Jenkins.
It is currently unclear if passengers can deplane during the refueling stop in Auckland.
Typically, during these “technical stops,” passengers must remain on the aircraft while crews change and tanks are refilled. This adds about two hours of ground time where you are stationary but still confined to your seat.
Comparing the Giants of the Sky
It is important to understand the distinction between this flight and other record holders.
The title for the “longest non-stop flight” still belongs to Singapore Airlines. Their flight from New York (JFK) to Singapore (SIN) covers about 9,537 miles without touching the ground. That flight takes roughly 19 hours.
Flight MU745 is technically a “direct” flight, not a “non-stop” flight.
The refueling stop in Auckland is the key difference. However, because it operates under a single flight number with the same plane, it offers a seamless experience compared to traditional transfers. You do not need to worry about missing a connecting flight or transferring luggage.
Here is how the two heavyweights stack up:
| Feature | Singapore Airlines (SQ24) | China Eastern (MU745) |
|---|---|---|
| Route | NYC to Singapore | Shanghai to Buenos Aires |
| Type | Non-stop | Direct (with stop) |
| Duration | ~19 Hours | ~29 Hours |
| Distance | ~9,500 Miles | ~12,000 Miles |
| Aircraft | Airbus A350-900ULR | Boeing 777-300ER |
This new Chinese route serves a growing economic need rather than just chasing records.
Trade between China and Argentina has exploded in recent years. There is a high demand for moving executives, laborers, and high-value cargo between the two nations efficiently.
Why Not Fly the Northern Route
You might wonder why the airline chose a stop in New Zealand instead of a traditional northern path.
Geopolitics and airspace restrictions play a major role in modern flight planning. Airspace closures over Russia due to ongoing conflicts have forced many airlines to rethink their maps.
Flying the southern route avoids potential geopolitical bottlenecks in the northern hemisphere.
The “southern corridor” offers a stable and politically neutral path across the Pacific Ocean. It relies on open ocean and friendly airspace in New Zealand. This ensures the schedule remains reliable regardless of tensions in Europe or North Asia.
Wind patterns also influence this decision.
The jet streams in the southern hemisphere can provide favorable tailwinds during certain legs of the journey. This helps the massive Boeing 777 burn fuel more efficiently over the vast stretch of the South Pacific.
This route represents a shift in global aviation strategy. Airlines are no longer just connecting major hubs via the shortest line on a map. They are creating durable links that bypass global instability to keep the world moving.
The launch of MU745 is a bold experiment in human endurance and engineering. It proves that no two cities on Earth are too far apart to be connected by a single ticket. While the journey is long, the ability to wake up on the other side of the world without changing planes is a game changer.
As aviation technology improves, we may see even more of these marathon routes. For now, the passengers on MU745 are pioneers on the longest commercial commute in the world.
