Warren Buffet invested 10b into four airlines

Warren Buffet‘s Berkshire Hathaway invested nearly $10 billion into American, Delta, United, and Southwest Airlines. Surprisingly enough, in 2013, Buffet referred to the country‘s airline industry as a "deathtrap for investors", according to Business Insider. Over the past two years, the chosen airlines have reported record profits, positive post-financial crisis capacity discipline and lower labor costs. Thus, instead of picking one airline to invest in, Warren Buffet selected all four.
