In the airline industry, it was originally intended as an intermediate level of service between economy class and first class, but many airlines now offer business class as the highest level of service, having eliminated first class seating. Business class is distinguished from other travel classes by the quality of seating, food, drinks, ground service and other amenities. In commercial aviation, full business class is usually denoted 'J' or 'C' with schedule flexibility, but can be many other letters depending on circumstances.
Economy class, also called third class, coach class, steerage, or to distinguish it from the slightly more expensive premium economy class, standard economy class or budget economy class, is the lowest travel class of seating in air travel, rail travel, and sometimes ferry or maritime travel.

They are seen as a strategy for market segmentation.
