Average Speed of Commercial Flights
Most commercial airplanes travel at an average speed of 800–900 km/h (500–560 mph).
This means a flight between two cities can be estimated by dividing the distance between them by the aircraft speed.
For example:
800 km distance → about 1 hour flight
2400 km distance → about 3 hours flight
However, actual flight time may vary due to weather conditions, air traffic, and flight routes.
