Cruise Speed (Normal). Compared to the average Turbofan-powered Narrow-body Commercial Passenger Plane, which cruises at a maximum of 472 knots, or 543 mph, the Airbus A320: 1  Can reach a 42 knot (48 mph) higher maximum cruise speed (a 8.9% margin).
Best Answer: The average commercial airliner flies at around 35,000 feet. Boeing 737,747,757,767,777. Airbus 320,380. A private luxury jet would fly at about the same, though the higher-end ones, like Gulfstreams, often fly at 40,000 feet. (The higher the altitude, the more efficient the plane is due to low air pressure/friction)
