Airline in the context of "Expropriation"

Public transport (also known as public transportation, public transit, mass transit, or simply transit) are forms of transport available to the general public. It typically uses a fixed schedule, route, and charges a fixed fare. There is no rigid definition of which kinds of transport are included, and air travel is often not thought of when discussing public transport—dictionaries use wording like "buses, trains, etc." Examples of public transport include city buses, trolleybuses, trams (or light rail), rapid transit (metro/subway/underground, etc.) and passenger trains and ferries. Public transport between cities is dominated by airlines, coaches, and intercity rail. High-speed rail networks are being developed in many parts of the world.

Most public transport systems run along fixed routes with set embarkation/disembarkation points to a prearranged timetable, with the most frequent services running to a headway (e.g., "every 15 minutes" as opposed to being scheduled for a specific time of the day). However, most public transport trips include other modes of travel, such as passengers walking or catching bus services to access train stations. Share taxis offer on-demand services in many parts of the world, which may compete with fixed public transport lines, or complement them, by bringing passengers to interchanges. Paratransit is sometimes used in areas of low demand and for people who need a door-to-door service.

Pan American World Airways, originally founded as Pan American Airways and more commonly known as Pan Am, was an airline that was the principal and largest international air carrier and unofficial flag carrier of the United States for much of the 20th century. The first airline to fly worldwide, it pioneered innovations such as jumbo jets and computerized reservation systems, and introduced the first American jetliner in 1958. Until its dissolution on December 4, 1991, Pan Am "epitomized the luxury and glamour of intercontinental travel", and it remains a cultural icon of the 20th century, identified by its blue globe logo ("The Blue Meatball"), the use of the word "Clipper" in its aircraft names and call signs, and the white uniform caps of its pilots.

Founded in 1927 by two U.S. Army Air Corps majors, Pan Am began as a scheduled airmail and passenger service flying between Key West, Florida, and Havana, Cuba. In the 1930s, under the leadership of American entrepreneur Juan Trippe, the airline purchased a fleet of flying boats and focused its route network on Central and South America, gradually adding transatlantic and transpacific destinations. By the mid-20th century, Pan Am enjoyed a near monopoly on international routes. It led the aircraft industry into the Jet Age by acquiring new jetliners such as the Boeing 707 and Boeing 747. Pan Am's modern fleet allowed it to fly larger numbers of passengers, at a longer range, and with fewer stops than rivals. Its primary hub and flagship terminal was the Worldport at John F. Kennedy International Airport in New York City.

Payload is the object or the entity that is being carried by an aircraft or launch vehicle. Sometimes payload also refers to the carrying capacity of an aircraft or launch vehicle, usually measured in terms of weight. Depending on the nature of the flight or mission, the payload of a vehicle may include cargo, passengers, flight crew, munitions, scientific instruments or experiments, or other equipment. Extra fuel, when optionally carried, is also considered part of the payload.

In a commercial context (i.e., an airline or air freight carrier), payload may refer only to revenue-generating cargo or paying passengers. A payload of ordnance carried by a combat aircraft is sometimes alternatively referred to as the aircraft's warload.

Nationalization (nationalisation in British English) is the process of transforming privately owned assets into public assets by bringing them under the public ownership of a national government or state. Nationalization contrasts with privatization and with demutualization. When previously nationalized assets are privatized and subsequently returned to public ownership at a later stage, they are said to have undergone renationalization (or deprivatization). Industries often subject to nationalization include telephones, electric power, fossil fuels, iron ore, railways, airlines, media, postal services, banks, and water (sometimes called the commanding heights of the economy), and in many jurisdictions such entities have no history of private ownership.

Nationalization may occur with or without financial compensation to the former owners. Nationalization is distinguished from property redistribution in that the government retains control of nationalized property. Some nationalizations take place when a government seizes property acquired illegally. For example, in 1945 the French government seized the car-maker Renault because its owners had collaborated with the 1940–1944 Nazi occupiers of France.

A common carrier in common law countries (corresponding to a public carrier in some civil law systems, usually called simply a carrier) is a person or company that transports goods or people for any person or company and is responsible for any possible loss of the goods during transport. A common carrier offers its services to the general public under license or authority provided by a regulatory body, which has usually been granted "ministerial authority" by the legislation that created it. The regulatory body may create, interpret, and enforce its regulations upon the common carrier (subject to judicial review) with independence and finality as long as it acts within the bounds of the enabling legislation.

A common carrier (also called a public carrier in British English) is distinguished from a contract carrier, which is a carrier that transports goods for only a certain number of clients and that can refuse to transport goods for anyone else, and from a private carrier. A common carrier holds itself out to provide service to the general public without discrimination (to meet the needs of the regulator's quasi-judicial role of impartiality toward the public's interest) for the "public convenience and necessity." A common carrier must further demonstrate to the regulator that it is "fit, willing, and able" to provide those services for which it is granted authority. Common carriers typically transport persons or goods according to defined and published routes, time schedules, and rate tables upon the approval of regulators. Public airlines, railroads, bus lines, taxicab companies, phone companies, internet service providers, cruise ships, motor carriers (i.e., canal operating companies, trucking companies), and other freight companies generally operate as common carriers. Under US law, an ocean freight forwarder cannot act as a common carrier.

A fare is the fee paid by a passenger for use of the public transport system: rail, bus, taxi, etc. In the case of air transport, the term airfare is often used. Fare structure is the system set up to determine how much is to be paid by various passengers using a transit vehicle at any given time. A linked trip is a trip from the origin to the destination on the transit system. Even if a passenger must make several transfers during a journey, the trip is counted as one linked trip on the system.
