What is the definition of a non-stop flight?

A non-stop flight is defined as the most direct route making no stops between the departure and arrival locations. This means that the flight travels directly from the origin city to the destination city without pausing at any intermediate airports. This type of service is preferred by many travelers for its convenience, as it minimizes travel time and eliminates the complexities and potential delays associated with layovers.

In contrast to a non-stop flight, other options involve additional stops or layovers. For example, the longest possible route with multiple layovers refers to flights that may take a longer path involving several stopovers, which complicates the travel process and increases total travel time. Additionally, a flight with intermediate stops for refueling also does not qualify as non-stop, since it would require at least one stop that disrupts the direct travel. Finally, a flight that only departs from the airport does not encompass the entire concept of what defines a flight, as it does not address the destination or whether any stops are made.
