An airline is a company that provides air transport services for traveling passengers and freight. Airlines lease or own their aircraft with which to supply these services and may form partnerships or alliances with other airlines for mutual benefit. Generally, airline companies are recognized with an air operating certificate or license issued by a governmental aviation body.
Airlines vary from those with a single aircraft carrying mail or cargo, through full-service international airlines operating hundreds of aircraft. Airline services can be categorized as being intercontinental, intra-continental, domestic, regional, or international, and may be operated as scheduled services or charters. Over the last couple of decades many new airlines have come into business which have helped people travel to various parts of the world easily. The large influx of airlines and passengers have also resulted in reducing the prices for airline tickets. These days reduced ticket prices attract a lot of passengers and it is a ploy that is used by most of the leading airlines around the world. The revenue of an airline also depends on their network for which they often make alliances so that a portion of the revenue can be shared among the airlines for development and maintenance.
