Shanghai’s debut low-altitude air route—linking Kunshan, Fuxing Island, and Pudong Airport—has successfully completed its test flight, revolutionizing regional travel in the Yangtze River Delta.     Cutting the Suzhou-to-Shanghai commute from 1.5 hours to just 20 minutes, the route enables seamless transfers, sightseeing, and even night flights showcasing the dazzling skyline. From Fuxing Island’s metro-adjacent vertiport, passengers can zip to Pudong Airport, soar over Lujiazui, or join a 30-minute aerial network to Jiaxing, Haining, and Shaoxing.     This milestone accelerates the era of integrated urban air mobility in China’s economic powerhouse.
