How fast do commercial airplanes fly? Commercial airliners, such as those operated by major airlines, often travel at speeds ranging from 500 to 600 mph (800 to 960 kph). These speeds, obtained at cruising altitudes of roughly 35,000 feet, enable airplanes to travel large distances in relatively short periods. Airplane manufacturers such as Boeing and Airbus design their aircraft to maintain these speeds for fuel economy and passenger comfort. However, weather patterns, air traffic control, and specific flight paths can all have an impact on the plane's actual speed at various points along the way. While takeoff and landing need slower speeds, once in the air, these aircraft cruise at extremely high speeds, ensuring speedy and efficient travel.
