Air charter Air charter is the business of renting an entire aircraft (i.e., chartering) as opposed to individual aircraft seats (i.e., purchasing a ticket through a traditional airline). While the airlines specialize in selling transportation by the seat, air charter companies focus on individual private aircraft and itineraries, urgent or time-sensitive cargo, air ambulance service, and other forms of "ad hoc" air transportation. Some air charters brokers have been given economic authority to sell seats on private jets with mixed success. Some air charter companies offer a large variety of aircraft, such as helicopters and business jets. Charter jet categories include turbo props, light jets, mid-size jets, super mid-size jets, heavy jets, long-range jets and VIP airliners.
