What is the definition of a charter flight?

A charter flight is defined as a non-commercial flight where an aircraft and its crew are leased or hired by a group or organization for a specific journey. This arrangement allows the hiring party to customize various aspects of the flight, such as the schedule, route, and even on-board services, based on their specific needs. Unlike scheduled flights, which operate on fixed routes and timetables, charter flights provide flexibility and can cater to various travel demands, such as corporate events, private group travel, or special occasions.

The other options focus on aspects that do not accurately define a charter flight, such as scheduled flights that serve multiple destinations or a service model where individual tickets are sold to the general public. Additionally, specifying a schedule limited to weekends does not encapsulate the broader and more flexible nature of charter flights.
