Add this new China Eastern Airlines flight to the list of the world's longest flights: the Shanghai-based carrier will launch direct service between Shanghai's Pudong International Airport (PVG) and Ministro Pistarini International Airport in Buenos Aires, Argentina (EZE), on December 4, 2025. This 10,600 nautical mile (12,100 regular miles) route on a Boeing 777-300 ER will break the record for the longest direct commercial flight in the world. A direct flight is not the same as a nonstop: This China Eastern flight includes a scheduled two-hour stopover in Auckland, New Zealand, but the flight number and plane itself will not change. China Eastern says the new route will simplify connections to South America — avoiding congestion and delays typical of European and U.S. stopovers, and be easier on timezone adjustment. It will operate the eastbound flight on Mondays and Thursdays, and the westbound flight on Tuesdays and Fridays.
