What is the fastest speed a passenger airplane flies at?
How fast does the world's currently fastest passenger plane fly (cruise speed)? Do any passenger planes fly faster than the speed of sound?
Best Answer
No, there is none and there will be none (until a new supersonic jet comes out). The reason is once supersonic speed is reached the drag resistance of the airplane increases enormously because shock waves are created and maintained. So you need much more fuel for a neglible increase of speed.

Jet fighters with supercruise still have an increase of drag, but first they are modeled to minimize the impact and second they are moving with Mach >1.2 to leave the so-called transsonic regime of Mach 0.8-1.2.
"Transsonic" means that the air around the plane moves in some regions with subsonic speed (slowest under the wings) and in some regions with supersonic speed (highest above the wings). In fact a normal jet has a small shock wave above the wings during the flight.
If every air molecule of the plane moves with supersonic speed, the drag decreases again because the interaction of the sub- and supersonic areas increase the drag.

How fast do passenger planes go mph?
Most commercial aircraft typically fly at around 460-575 mph, or 740-930 km/h, according to Flight Deck Friend. But private jet speed can vary depending on a variety of factors, such as the weight onboard and the weather conditions.What commercial airline flies the fastest?
Tupolev TU 144 is the fastest commercial airliner that has taken the skies at up to 1,510 mph or 2,430 kilometres per hour speed until now. Although the aircraft is not used for commercial flights, it is still used by the military of Russia for various missions and space programs along with the training as well.Can anything go Mach 10?
On November 16, 2004, NASA made history by launching the X-43A, the first-ever air-breathing hypersonic vehicle, into the atmosphere, achieving Mach 10 speed. The X-43A separated from its booster and accelerated on scramjet power at nearly ten times the speed of sound (7000 MPH) at roughly 110,000 feet.10 Fastest Passenger Planes In The World
