Is C919 fuel efficient?
Summary: The C919 consumes more fuel as the airframe is larger for the same seating capacity as the A320neo. Due to a lack of airframe maturity, the maintenance costs will also be higher. One report estimated the C919 to be in the range of US$90-100 million. This is lower than US$111 million for the Airbus A320neo and US$121 million for the Boeing 737 MAX. That said, the price for the C919 is steeper than the US$50 million estimated previously.
