How fast does a commercial air liner go?

Commercial airliners typically cruise at speeds ranging from 450 to 550 miles per hour (720 to 890 kilometers per hour). This speed range allows for efficient flight operations, fuel consumption, and passenger comfort. However, the actual cruising speed of an airliner can vary depending on several factors, including aircraft type, weather conditions, air traffic control regulations, and airline operational procedures.

Here is a general overview of the cruising speeds of different types of commercial airliners:

1. Narrow-body airliners: These are smaller passenger planes commonly used for short- to medium-haul flights. Examples include the Boeing 737, Airbus A320, and Embraer E-Jets. Narrow-body airliners typically cruise at speeds around 450-480 mph (720-770 km/h).

2. Wide-body airliners: These are larger passenger planes used for long-haul flights. Examples include the Boeing 747, Airbus A380, and Boeing 777. Wide-body airliners generally cruise at higher speeds compared to narrow-body planes, ranging from 520-550 mph (840-890 km/h).

3. Regional jets: These are small commuter planes used for short-distance flights. Regional jets typically cruise at speeds around 400-450 mph (640-720 km/h).

It's important to note that the cruising speeds mentioned above are approximate values and can vary slightly based on specific aircraft models and operational conditions. Additionally, during takeoff and landing, airliners fly at lower speeds to ensure safety and passenger comfort.
