上海航空
On 11 June 2009, it was announced that China Eastern Airlines would merge with Shanghai Airlines. The merger of China Eastern and Shanghai Airlines was expected to reduce excess competition between the two Shanghai-based carriers while consolidating Shanghai's status as an international aviation hub. In February 2010 the merger was completed. Shanghai Airlines became a wholly owned subsidiary of China Eastern Airlines. However, Shanghai Airlines retained its brand and livery. The new combined airline was expected to have over half of the market share in Shanghai, the financial hub of China. China Eastern Airlines also acquired China United Airlines in October 2010.
