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.
Instead, a political party is a group of dedicated people who come together to win elections, operate the government, and determine public policy. So, you can see that this is anything but the fun type of 'party' that we usually think of when we hear the word.
