Print reporters who have to work the dead week between Christmas and New Year's are always scratching for news to fill the time and the papers, so here's a live possibility. A source with connections at Los Angeles World Airports says that executive director Lydia Kennard hopes to leave in January and has put a rush on the search for her replacement. Inside candidates and experienced airport executives from elsewhere were interviewed on short notice last week, the source says, reportedly by a subcommittee of airport commissioners that included chairman Alan Rothenberg, Walter Zifkin and Michael Lawson. The second round of interviews has begun, he says, speculating that Kennard, the city's second-highest-paid department head, may be headed north to be Secretary of the Business, Transportation and Housing Agency in Gov. Schwarzenegger's next term.
