What is an important aspect of a "Charter" flight?

An important aspect of a charter flight is that it is typically booked for specific groups or events. Charter flights are often arranged for particular organizations, parties, or special occasions, allowing a customized travel experience that meets the specific needs of the group involved. This can include tailored itineraries, flexibility in scheduling, and travel to destinations that may not be well-served by commercial airlines.

While charter flights can sometimes be less expensive than commercial flights depending on the circumstances and timing, that is not a defining characteristic. Similarly, charter services are not restricted to peak travel seasons; they can operate year-round. Additionally, although there are cargo charter flights, the primary use of charter flights is for transporting passengers, not solely for cargo transport. Hence, the focus on group or event bookings is what makes this aspect essential to understanding charter flights.
