Commercial planes deliberately fly below the speed of sound (Mach 1, about 767 mph). Breaking it creates a sonic boom—a loud, window-rattling crack. That’s bad for naps, bad for buildings, and bad for your ears.
Only two commercial aircraft ever broke the sound barrier: the Concorde and the TU-144. The Concorde zipped at Mach 2.04—over 1,350 mph. That’s faster than a bullet from a handgun. You could fly from London to New York in under three hours. Champagne never tasted so fast.
Sadly, the Concorde retired in 2003. Now we’re back to “slow” 600 mph flights. But don’t pity us—pity the guy stuck in a 747 restroom during turbulence.

Why Does Speed Vary by Plane?
Not all planes are built equal. A little Embraer E175 regional jet cruises at about Mach 0.78—around 515 mph. Meanwhile, a Boeing 787 Dreamliner hits Mach 0.85, or 561 mph. The difference? Wings, engines, and aerodynamics.
Shorter planes? They feel slower because you’re closer to the ground. Longer flights? They climb higher, where the air is thinner and drag drops. That’s why a cross-country flight from LA to New York averages about 560 mph—yet you feel like you’re floating in a metal tube.
And then there’s the Airbus A380. This massive double-decker beast cruises at Mach 0.85, same as a fighter jet from the 1960s. Size doesn’t mean slow—it means more snacks.
