Buffett says United Airlines bungled the case of the passenger dragged off a plane in April 2017, and he is criticizing the CEO’s handling of the incident. Buffett, whose Berkshire Hathaway Inc. is a major shareholder of United and other big U.S. airlines, said Monday, May 8, 2017, that the recent spotlight on poor customer service in the airline industry doesn’t change his investment strategy.
