April 3, 2025, © Leeham News: The COMAC C919 is finding its first customers outside China, which gives us a reason to examine the aircraft.

Last week, we estimated its efficiency versus its Western “look-a-like,” the Airbus A320neo. Now, we look at new variants that have been announced and how competitive these would be.

Summary:

• The C919, sized like an A320neo, is the first variant in a family of aircraft.
• The next C919 variant is a shorter model for hot and high airfield operation.
• The following variant is an A321neo-sized aircraft.
