Quick Answer. The average cruising flight speed for commercial jets is around 540 mph. This is based on the most popular commercial jets in operation, the Boeing 747 family.
Current commercial aircraft fly with a cruise speed depending on the model and make of the aircraft that ranges between Mach 0.81 through Mach 0.86, that is a speed in the range of 900 km per hour. We call this subsonic flight. Concorde flew with a cruise speed of about 2,100 km per hour. The future generations of very fast commercial aircraft will fly with speeds of 4-5 times the speed of sound, that is in the range of 4,000-5,000 km per hour. History of supersonic flight. Development of supersonic flight started already in the early fifties of the 20 th century, initially
