Passengers are in their seats for over a day as the plane travels from Shanghai, China, to Buenos Aires, Argentina. The route from China to Argentina takes more than 25 hours, while the return leg takes an additional four. ‌The flight has set the record for the longest commercial flight route in the world, yet it can't secure the world's longest direct flight route title because it makes a stop. The title of the longest non-stop flight is currently held by Singapore Airlines.
