What is an Airline?

An airline is a company that provides air transport for either passengers or freight usually with a recognized operating certificate or license. Airlines either rent or buy aircraft to operate routes. There are many different kinds of airlines. There are international airlines which operate larger fleet of bigger aircraft like the Boeing 747, 777, 787, Airbus A380, A340, and A330 mostly across the world. Some of the these airlines are Lufthansa, Northwest airlines, Singapore airlines, Emirates, KLM, British Airways, and Air France. Then there are Intercontinental airlines which operate routes within a continent with midsized planes like the Boeing 757,767, Airbus A300 and A310. These airlines are United and American airlines. Last but not least there are domestic airlines which operate routes within a country. They use smaller short range jets like the Boeing 737, Airbus A318, A319, A320 and A321. They mostly operate within the U.S and are Southwest airlines, Spirit airlines and Jetblue airlines. These are called "Low Cost Airlines" because they offer low fares in exchange for eliminating many passenger services like complimentary drinks and snacks. They also usually operate the same planes to reduce operating costs.
