The October 28 post, Pratt & Whitney, stated that the Boeing 737 Max and the Airbus 320neo use the Pratt & Whitney engine.
The Boeing 747 Max uses the CFM International engine, also quieter and more fuel-efficient.
The Airbus 320neo uses and will use the Pratt & Whitney engine on its launch. The Airbus 320neo is also available with the CFM International engine.
The original post has been corrected to identify the launch version of the Airbus 320neo as the competing aircraft with the same model Pratt & Whitney engine.
