How Fast Do Different Types Of Commercial Aircraft Fly?

How fast do commercial aircraft fly? Unlike fighter jets, commercial aircraft are built for safety and commercial viability. The cost of operating supersonic jet aircraft is generally prohibitive (especially as overland routes are typically banned), meaning that the famous Concorde remains the only example of a successful supersonic passenger flight. Commercial jet-powered aircraft all fly at similar speedsbetween 550 and 600 mph or Mach 0.79 to Mach 0.855, with narrowbodies flying a little slower than widebodies.
