Xiamen Airlines
On 10 January 2011, Saudi Arabian Airlines signed an agreement to join SkyTeam in 2012. On 28 February the same year, Middle East Airlines agreed to join the alliance. Member airlines Delta and Air France-KLM appointed Goldman Sachs in late to advise them on a potential bid for Sir Richard Branson's 51% stake in Virgin Atlantic, which could lead to the airline joining SkyTeam and would sharply increase the alliance's footprint in London. Rivals Star Alliance and Etihad Airlines are also investigating competing options with regard to Virgin Atlantic. China Eastern Airlines joined the alliance on 21 June 2011, along with its subsidiary, Shanghai Airlines, to become the 14th member. Later in 2011, on 28 September, China Airlines joined the alliance. In the same year, Xiamen Airlines committed to be incorporated as a full member by the end of 2012, with their entry supported by China Southern Airlines.
