When I was still an assistant working at LATCC, one of my colleagues thought to ask why the LAX flights never filed LAX as destination, always Seattle. He was told they would file to Seattle with LAX as first diversion, then if they had the fuel after crossing the ocean they would carry on to LAX and miss SEA.
