Flight duration refers to the total time taken for an aircraft to travel from its departure point to its destination. This time includes the period spent in the air, as well as any delays during takeoff and landing. Factors such as weather conditions, air traffic, and the specific flight path can influence the overall duration. Airlines often provide estimated flight durations when booking tickets, which can help passengers plan their travel. For example, a flight from New York to Los Angeles typically takes about 6 hours. However, actual flight times may vary based on the aircraft type and operational circumstances.
