LONDON—The chief executive of Ryanair Holdings PLC, one of Boeing biggest customers, took aim at the planemaker’s sales team and its 737 MAX delivery schedule and said the company needed to reboot its commercial-aircraft division.
Michael O’Leary also questioned Boeing’s pending shift of its headquarters from Chicago to Virginia. While the move “may be good for the defense side of the business, it doesn’t fix the fundamental underlying problems on the civilian aircraft side in Seattle,” Mr. O’Leary told analysts on a conference call after the company’s earnings release Monday. “And Seattle needs a reboot. It needs a reboot quickly.”
