An airline is a company that provides air transport services for traveling passengers or freight. Airlines use aircraft to supply these services and may form partnerships or alliances with other airlines for codeshare agreements, in which they both offer and operate the same flight. Generally, airline companies are recognized with an air operating certificate or license issued by a governmental aviation body. Airlines may be scheduled or charter operators.

A decade later it had acquired Piedmont Airlines and Pacific Southwest Airlines (PSA), and was one of the U.S.'s seven transcontinental legacy carriers. In 1997, it rebranded as US Airways.

A regional airline is a general classification of airline which typically operates scheduled passenger air service, using regional aircraft, between communities lacking sufficient demand or infrastructure to attract mainline flights. In North America, most regional airlines are classified as "fee-for-departure" carriers, operating their revenue flights as codeshare services contracted by one or more major airline partners. A number of regional airlines, particularly during the 1960s and 1970s, were classified as commuter airlines in the Official Airline Guide (OAG).
China Southern Airlines is a major airline in China, headquartered in Guangzhou, Guangdong. It has one of the three major airlines in the country, along with Air China and China Eastern Airlines.

An airline hub or hub airport is an airport used by one or more airlines to concentrate passenger traffic and flight operations. Hubs serve as transfer points to help get passengers to their final destination. It is part of the hub-and-spoke system. An airline may operate flights from several non-hub (spoke) cities to the hub airport, and passengers traveling between spoke cities connect through the hub. This paradigm creates economies of scale that allow an airline to serve city-pairs that could otherwise not be economically served on a non-stop basis. This system contrasts with the point-to-point model, in which there are no hubs and nonstop flights are instead offered between spoke cities. Hub airports also serve origin and destination (O&D) traffic.
