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.
A political machine is a political organization in which an authoritative boss or small group commands the support of a corps of supporters and businesses (usually campaign workers), who receive rewards for their efforts.
The key to a political machine is patronage: holding public office implies the ability to do favors (and also the ability to profit from graft). Political machines generally steer away from issues-based politics, favoring a quid pro quo (something for something) with certain aspects of a barter economy or gift economy: the patron or boss does favors for the constituents, who then vote as they are told to.
