Passage: Airline alliance -- In 2010 Richard Branson, chairman of the Virgin Group, announced his intention to form a fourth alliance among Virgin branded airlines (Virgin Atlantic; Virgin America; and the Virgin Australia Holdings group of airlines). Then in September 2011, Branson said that Virgin Atlantic would join one of the existing alliances; this idea was repeated in October 2012. In December 2012, Delta Air Lines purchased Singapore Airlines' 49% stake in Virgin Atlantic for 224 million. Virgin America was absorbed into Alaska Airlines, which is not a member of any alliance, in April 2018.
