JALways became a wholly owned subsidiary of Japan Airlines on March 9, 2001 through an exchange of shares. The change in ownership enabled JAL to consolidate and improve management and operational efficiency in the JAL Group's international passenger operations, part of the JAL Medium Term Corporate Plan 2000-2002.[5] The airline introduced new uniforms for its cabin crew on April 1, 2005, and retired its last McDonnell Douglas DC-10 on October 31.[2] JALways became an affiliate member of Oneworld on April 1, 2007, together with four of its sister airlines, in the alliance's biggest expansion in its young history.[6]
