“With the MD-11, the flight schedule was from Shanghai to Anchorage for refueling and then to Memphis,” says Li Tao, a senior ramp agent in Shanghai. “Now that we use the 777F, we have a nonstop flight from Shanghai to Memphis. The flight leaves Shanghai two hours later, so the cutoff time for our customers is also two hours later.” And in global commerce, two hours can change the game for a business.
