On May 5, China Eastern Airlines flew flight MU28 from Shanghai Hongqiao Airport to Beijing Capital Airport using COMAC's first C919 jumbo aircraft delivered in the world. Boeing and Airbus, the world's two major passenger aircraft manufacturers, issued congratulations.

A number of foreign media believe that the commercial first flight of C9 19 is a "milestone" event. China hopes to break the longstanding monopoly of Airbus and Boeing in world's aviation industry. The Financial Times believes that looking forward to the long-term development of China's passenger aircraft industry may shake the "duopoly" position of Boeing.
