What term represents a collaboration of multiple commercial operators for transportation?

The term that accurately represents the collaboration of multiple commercial operators for transportation is commonly referred to as "Interline." This concept involves agreements between different airlines that allow them to handle passengers traveling on itineraries that involve multiple carriers. When airlines interline, they coordinate ticketing and baggage handling and can link schedules to facilitate smoother connections for passengers.

This arrangement is crucial in the aviation industry as it allows airlines to offer more extensive route networks and improve customer convenience by streamlining travel processes across different carriers. In contrast, while "Airline Alliance" refers to formal agreements between airlines to cooperate in areas such as marketing and scheduling, "Joint Venture" typically denotes a more integrated business partnership often involving shared revenues and costs. "Partnership Flight" is not a widely recognized term within the airline industry.
