At both airports scenes, the plane shown is a Boeing 737. However, when it starts its take-off run, an Airbus A-320 is seen instead.
At the Yaoundé airport scene, a RwandAir's Boeing 737 is seen at the platform. RwandAir doesn't fly (and has never flown) to Yaoundé. The only destination it serves in Cameroon is Douala.
