Leaving the aircraft after a flight is referred to as what?

The term "deplaning" specifically refers to the process of passengers exiting an aircraft after a flight has arrived at its destination. This term is commonly used in aviation and is distinct from other terms. It emphasizes the action of leaving an aircraft, particularly in a travel-related context, which makes it the most appropriate choice.

While "deboarding," "disembarking," and "departing" are related terms in the context of air travel, they can imply slightly different actions. "Deboarding" is less commonly used and can sometimes refer to the act of leaving any type of vehicle, not just an aircraft. "Disembarking" generally refers to leaving a mode of transport, including boats and ships, and is not exclusive to airplanes. "Departing" simply denotes the action of leaving in a broader sense and does not specifically refer to leaving an aircraft.

In aviation terminology, "deplaning" is the preferred term, aligning specifically with the activity of leaving the airplane after a flight, which clearly distinguishes it from the other options.
