air marketing liveries Alliance brands Three multinational worldwide airline alliances have grown and developed their own aircraft liveries and corporate identities which encompass and transcend major carriers, mainline carriers, legacy carriers, and flag airlines' individual airline identities along with any ties to regional, geopolitical, national boundaries, and government heritages. Oneworld, SkyTeam, and Star Alliance are the mutually agreed upon "airline alliance liveries" of large numbers of independent and separately owned airlines working together as one through a system of codeshare agreements, rather than the colors of any one certificated airline.

They may carry sub-branding such as Airlink, Connection, Eagle, or Express juxtaposed with the more widely recognised carrier name. A recent trend, in North America is for the regional airline d/b/a Express, Eagle, or Connection, is to operate the aircraft in full mainline airline markings, leaving the operating regional airlines name in only very small letters, close to the forward entry door. Such brandings noted to cause confusion among travelers, as in the case of the Colgan Air Continental Connection Flight 3407 crash in which people identified the flight with Continental Airlines, although it was actually flown by Colgan Air. Non airline liveries Government Air transports of heads of state and government are often painted in unique color schemes. The US President's aircraft, Air Force One, uses a light-blue and sky-blue color scheme, with the Seal of the President of the
