An airline is a company that provides air transport services for traveling passengers and freight. Airlines utilize aircraft to supply these services, and may form partnerships or alliances with other airlines for codeshare agreements. Generally, airline companies are recognized with an air operating certificate or license issued by a governmental aviation body.
Airlines vary in size, from small domestic airlines to full-service international airlines with double decker airplanes. Airline services can be categorized as being intercontinental, domestic, regional, or international, and may be operated as scheduled services or charters. The largest airline currently[when?] is American Airlines Group.
Airports serving domestic flights only are known as domestic airports.
Domestic flights are generally cheaper and shorter than most international flights. Some international flights may be cheaper than domestic ones due to the short distance between the pair of cities in different countries, and also because domestic flights might, in smaller countries, mainly be used by high paying business travellers, while leisure travellers use road or rail domestically.
Some smaller countries, like Singapore have no scheduled domestic flights.
