A list of all Air Charter Service Airlines. This list focuses on charter airlines including international, intercontinental, intra-continental, domestic, and regional services. While air travel was once seen as a symbol of luxury and wealth, today it is the preferred method of travel by nearly everyone for great distances. That said, air charter services continue to be an exclusive perk of corporations and the very wealthy. A charter airline is a service in which instead of reserving a seat, one reserves an entire plane. Airplanes are the safest way to travel, and while commercial space flight is currently in the works, the plane will continue to be the method-of-travel of choice for many decades to come.
