Wings Alliance

Wings (for clarity the Wings Alliance) was the working name of a proposed airline alliance to be anchored by the American carriers Northwest Airlines and Continental Airlines of USA with the European flag carriers KLM of the Netherlands and Italy's Alitalia. Although these airlines cooperated with one another through code-sharing and frequent flyer program coordination, no formal association was ever announced. It was rendered superfluous in September 2004 when most of its participants joined the SkyTeam alliance.

Northwest and KLM had begun cooperating in 1989, but the formation of the Star Alliance in 1997 led by United Airlines and Lufthansa represented a new direction for airline marketing. Passengers could book seamless itineraries across the coordinated schedules of member carriers, accrue and redeem frequent flyer miles in their preferred program, and enjoy reciprocal lounge access and other elite flyer privileges. In September 1998, American Airlines, British Airways, Qantas, Canadian Airlines and Cathay Pacific announced the creation of a rival alliance, Oneworld.

Non-aligned airlines maneuvered to form their own partnerships. Swissair and Sabena built a network around the Qualiflyer program and Air France and Delta Air Lines announced a partnership that would grow into the SkyTeam alliance. Northwest and KLM, which had begun cooperating with Continental in 1998, did not immediately reorganize their tripartite relationship into a third, competing alliance; however, industry analysts widely expected the move would come in 1999. Indeed, in the spring of that year, leaders of the labor unions representing the airlines' pilots met to coordinate negotiations. KLM had merged its cargo operations with those of Alitalia, and with Northwest extended its partnership to Alitalia effective November 1, 1999. In December, Continental received regulatory approval to partner with Alitalia, bringing membership of the nascent alliance to four.
