What defines a 'Non-stop' flight?

A non-stop flight is clearly defined as a flight that travels directly to its final destination without making any stops along the way. This means that once passengers board the aircraft, they do not disembark until reaching their destination, making the travel experience more straightforward and generally quicker compared to flights that involve stops or layovers.

In contrast to the other options, a flight making several stops would be classified as a multi-stop flight, while a flight with one layover suggests that passengers will have to change planes, which also does not fit the non-stop definition. Lastly, a flight that circles back to the departure city would be considered a round trip, but it does not fit into the category of direct travel to a planned destination without interruptions. Therefore, the definition aligns perfectly with the characteristics of a non-stop service.
