What characterizes a 'Non-stop' flight?

A 'Non-stop' flight is characterized by a direct route to the destination without any scheduled stops along the way. This means that once passengers board the aircraft, they remain on it until it arrives at the final destination. Non-stop flights are designed to be the most efficient option for travelers, allowing them to reach their destination quickly without the inconvenience of changing planes or waiting at layover airports.

In contrast, a flight that involves multiple layovers indicates that passengers would have to change planes or wait at different airports, which does not align with the concept of non-stop travel. Similarly, routes with scheduled diversions or a midway stop for refueling involve interruptions in the journey, which also contradicts the definition of a non-stop flight. Thus, the essence of a non-stop flight is its uninterrupted travel from origin to destination.
