On 10 November 2009, Oneworld welcomed Mexicana and its subsidiaries, MexicanaClick and MexicanaLink, after the airline accepted a formal invitation to join the alliance on 9 April 2008. Mexicana and its affiliates added 26 destinations to the alliance map. Mexicana was a former member of Star Alliance, leaving the group in March 2004 when it terminated its codeshare agreement with United Airlines and opted for bilateral agreements with Oneworld members American Airlines and Iberia. On 2 August 2010, Mexicana filed for insolvency proceedings in Mexico and bankruptcy protection in the United States with its financial situation deteriorating. The airline suspended all operations from 28 August 2010. With the group under Mexican court protection, it has remained an inactive member of Oneworld since then.
