575 mph.
It would depend on the make and model of the plane
There is no certain cruising altitude for a commercial airline. it depends on where they are flying and how long they fly. most airlines fly above 10,000 ft. the max altitude is around 41,000 ft.
A commercial airliner, such as a Boeing 747, can reach speeds of around 700 MPH at cruising altitude.
Cruising speed is about 150 mph.
Yes, the Concorde was one of the fastest commercial airplanes ever made. It had a cruising speed of around 1,350 mph (2,180 km/h), which allowed it to fly at supersonic speeds, faster than the speed of sound.
Max cruising speed is 487 knots, economy(most efficient) cruising speed is 454 knots.
The Aerospatiale/BAC Concorde has a cruising speed of 1,350 m.p.h. (Mach 2.04) t 49,200 ft.
the max speed is over 300 possibly 350 mph. Really depending if the plane is using flaps or the wind speed is at its greatest.------------------------------------------------------------------------------------------------------------------Wikipedia shows the typical cruising speed as Mach 0.77, 570 mph or 917 kph.Typical cruising speed 570-580 mph. -
Cruising speed was 68 mph, with a maximum speed of 81 mph.
No, the Tupolev Tu-144 was the only other commercial plane to date to fly faster then the speed of sound.
The Lockheed SR-71 Blackbird, with a cruising speed of Mach 3.2.
