The C919, made by Commercial Aircraft Corp of China Ltd, is one of five ordered by China Eastern to be delivered through 2023. It is due to start flying commercially next spring.

Comac, as the manufacturer is known, added 300 new orders in November from undisclosed buyers, on top of 815 already booked for the narrowbody, mostly from Chinese lessors.

Comac has struggled to drum up interest for the C919 overseas, not helped by 14 years of planning, testing and missed deadlines. The plane was awarded a production certificate in November, but Comac hasn’t provided details on how many it will roll out a month, an industry benchmark to gauge demand.

The C919 delivered to China Eastern has 164 seats in two cabins, including eight in business class, and 20 drop-down screens to play videos. The middle seat in each row is 1.5cm wider than the neighbouring ones. According to Comac’s website, the C919 is designed to carry 158 to 192 passengers.

China Eastern previously disclosed the aircraft is US$99 million at the list price. Costs aren’t published for the similar-sized Airbus 320neo series and Boeing 737 Max family, but they’ve previously listed equivalent aircraft at US$111 million to US$122 million. China’s four major airline groups have about 2,200 Airbus and Boeing planes between them.

While the C919 delivery is significant, the plane faces an uphill battle to challenge the European and American manufacturing duopoly. Airbus received one of its biggest orders ever from China over the summer and Boeing planes are widely used in the country, even though its 737 Max has yet to return to commercial service.

Comac’s suppliers include General Electric Co, Honeywell International Inc and CFM International Inc, a joint venture between GE and Safran SA. China Eastern had a fleet of 750 jets at the end of June, including 357 A320s and 288 Boeing 737s.
