An airline provides air transport services for passengers or freight, generally with a recognized operating certificate or license. Airlines lease or own their aircraft with which to supply these services and may form partnerships or alliances with other airlines for mutual benefit.
Airlines vary from those with a single airplane carrying mail or cargo, through full-service international airlines operating hundreds of airplanes. Airline services can be categorized as being intercontinental, intra continental, domestic, or international and may be operated as scheduled services or charters.
DELAG, Deutsche Luftschiffahrts-Aktiengesellschaft was the world's first airline. It was founded on November 16, 1909 with government assistance, and operated airships manufactured by The Zeppelin Corporation. Its headquarters were in Frankfurt. (Note: Americans, such as Rufus Porter and Frederick Marriott, attempted to start airlines in the mid-19th century, focusing on the New York–California route. Those attempts foundered due to such mishaps as the aircraft catching fire and the aircraft being ripped apart by spectators.) The five oldest non-dirigible airlines that still exist are Australia's Qantas, Netherlands' KLM, Colombia's Avianca, Czech Republic's Czech Airlines and Mexico's Mexicana. KLM first flew in May 1920 while Qantas (for the Queensland and Northern Territory Aerial Services Limited) was founded in Queensland, Australia in late 1920.
