What is the definition of a direct flight?

A direct flight is defined as a flight that has no scheduled stops between the departure and arrival points. This means that passengers board the aircraft at the origin and disembark only after reaching their final destination without having to change planes or make layovers. While direct flights may occasionally involve the same aircraft being used for another route, it is crucial to understand that they do not involve scheduled stops at other airports.

In contrast, options that mention layovers, meal inclusions, or multiple airlines do not pertain to the core definition of a direct flight. A flight that allows layovers may be convenient, but it doesn’t meet the criteria of a direct flight if it requires changing planes or stopping at other airports. Similarly, meals may enhance the travel experience but are not a defining characteristic of the flight type. Lastly, a flight operated by multiple airlines refers to code-sharing relationships or partnerships but does not indicate whether the flight is direct or not. Thus, without scheduled stops, a direct flight remains distinctly defined.
