Buffet adds 4 airlines including United to Berkshire's portfolio
 

Berkshire Hathaway just released SEC filings show that the company has taken a stake in three of the four major airline companies — American Airlines, United Continental Holdings and Delta Air Lines.
But CNBC can report exclusively that Berkshire also has taken a stake in the fourth major carrier, Southwest Airlines.
The move into airlines is a shocking reversal for Warren Buffett, who has shunned the industry for decades following a volatile investment he made in US Airways back in 1989. He bought $358 million in preferred shares of US Airways, which almost immediately dropped in value.
