The world's longest single-flight route was officially launched early on Thursday morning (December 4), when China Eastern Airlines flight MU745 took off from Shanghai for Buenos Aires, Argentina. This record-breaking route spans about 20,000 kilometers as a one-way service, requiring a refueling stop in Auckland, New Zealand. It connects the Eastern and Western hemispheres and is expected to cut travel time between China and South America by over four hours. | CGTN
