United airline CEO apologizes for miss treating passenger

After two days of conflicting corporate statements, falling stocks, and swelling outrage, United Airlines entered full-scale mea culpa mode Tuesday afternoon, as its chief executive announced an internal investigation into a Sunday-evening flight in which a man was dragged violently from his seat so a crew member could have it.‘‘I continue to be disturbed by what happened on this flight,’’ United chief executive Oscar Munoz said in a prepared statement.

‘‘I deeply apologize to the customer forcibly removed and to all the customers aboard. No one should ever be mistreated this way.’’

‘‘We are going to fix what’s broken so this never happens again,’’ Munoz wrote — promising a report on the beleaguered airline’s policies on calling police, transferring crew, and ‘‘how we handle oversold situations.’’
