Los Angeles World Airports is set to name its No. 2 executive as interim chief executive to replace current Chief Executive Deborah Flint, who moved up her previously announced departure date to the end of this month. LAWA, which operates Los Angeles International and Van Nuys airports, said Thursday that current chief operating officer Justin Erbacci had been put forward for the interim chief executive post by Board of Airport Commissioners President Sean Burton. LAWA’s full board will consider the appointment at its next meeting on Dec. 19. If approved by the board, Erbacci would become interim chief executive on Jan. 1. The announcement also said Flint’s departure would now take place at the end of December. She had originally agreed to stay on until March to give more time for an executive transition. Flint has accepted the chief executive post at Toronto’s airport system.
