Could Delta or Southwest be targets for a Warren Buffett acquisition?

No. 3: Warren Buffett | Net worth: $74.5 billion | Once dubbed the ÒOracle of Omaha,Ó Buffett is one of the most successful investors. He is the chairman of Berkshire Hathaway, which owns major companies like Dairy Queen, Duracell, and Geico.

After billionaire investor Warren Buffett said last month he wouldn’t rule out buying an entire airline, one analyst is exploring the possibility that Delta Air Lines or Southwest Airlines could be targets.

Buffett's company Berkshire Hathaway has stakes in Delta, American, United and Southwest. "I wouldn't rule out owning an entire airline," Buffett said on CNBC in late February. Atlanta-based Delta is the largest carrier at Hartsfield-Jackson International, while Southwest is the second-largest.

According to Wolfe Research senior analyst Hunter Keay in a Friday note to investors, most analysts appear to be focusing on Southwest and Delta "as the most likely two candidates, which seem like logical choices due to cash flow, balance sheet, brand reputation, and general overall quality." Keay wrote that Southwest "has the characteristics of a typical" Berkshire Hathaway acquisition candidate, but noted that Berkshire took interest in a presentation by American Airlines CEO Doug Parker, according to media reports.
