What is the definition of a charter flight?

A charter flight is defined as a flight that is operated solely for a specific group or company that leases both the aircraft and the crew. This arrangement allows the group to tailor the flight experience to their specific needs, such as selecting the departure times, destinations, and onboard services, which differ significantly from scheduled flights.

In contrast, scheduled flights are available to the general public and follow a fixed timetable, while cargo-only flights do not carry passengers at all. The option that mentions open seating also refers to a specific aspect of scheduling flights rather than the nature of charter flights. Therefore, the distinction of charter flights lies primarily in their customized nature and the exclusivity for the group that hires them.
