China's ARJ21 regional jetliner hit a record high annual delivery of 24 aircraft in 2020, according to the Commercial Aircraft Corporation of China (COMAC) Tuesday.

As of the end of 2020, COMAC had delivered a total of 46 ARJ21 aircraft, said the Chinese commercial plane maker, also the developer of C919 single-aisle passenger aircraft.

The China-developed regional jetliner model has entered a phase of accelerated batch delivery and large-scale commercial operation.

COMAC has delivered ARJ21 airplanes to six Chinese airlines: Air China, China Eastern Airlines, China Southern Airlines, Chengdu Airlines, China Express Airlines, Jiangxi Air and Genghis Khan Airlines.

As of the end of 2020, these ARJ21 jetliners have safely carried around 1.6 million passengers, COMAC said.
