The Boeing 737 MAX is slowly but surely reentering service in China. After China Southern Airlines and Hainan Airlines reintroduced the 737 MAX earlier this year, Fuzhou Airlines has become the third Chinese airline to resume commercial service with the type. China Southern had its first 737 MAX flight on January 13th, after a hiatus of nearly four years. China Southern operated two MAX flights that day, the first one from Guangzhou to Zhengzhou (CZ3960) and the second one from Guangzhou to Wuhan (CZ8726).
