Commercial planes typically cruise at speeds ranging from about 480 to 575 mph (770 to 930 km/h), which corresponds roughly to Mach 0.74 to Mach 0.85 depending on the aircraft model and conditions

. For example:

• Boeing 737 cruises around Mach 0.74 to 0.79 (567 to 606 mph)
• Boeing 747 and Airbus A380 cruise near Mach 0.85 (about 570 mph)
• Boeing 787 and Airbus A380 also cruise near Mach 0.85 (around 562 to 650 mph)

The average cruising speed for long-haul commercial jets is typically between 547 and 575 mph (880 to 926 km/h)

. Speeds vary by phase of flight:

• Takeoff speeds are usually between 160 and 180 mph
• Landing speeds range roughly from 130 to 160 mph

Other types of planes fly at different speeds:

• Private jets: 400 to 700 mph
• Military jets: can exceed 1,500 mph for fighters like the F-22
• Small single-engine planes: around 140 to 200 mph

In summary, commercial airliners generally fly at about 500 to 600 mph during cruise, optimized for efficiency and passenger comfort, while other aircraft types can be much faster or slower depending on their design and purpose
