Los Angeles World Airports on Monday projected a $647.6 million operating budget for the fiscal year that begins July 1, according to preliminary figures.  The operating budget covers day-to-day expenses at Los Angeles International Airport and the agency’s smaller airports in Ontario and Van Nuys.  On its own, LAX’s operating costs during the 2010 fiscal year are expected to increase 1.8 percent to $565 million, while revenue is projected to increase 5.8 percent to $705 million.  LA/Ontario International Airport is expected to see a 14.6 percent budget cut, while Van Nuys Airport will experience 10.9 percent in operating reductions, according to the proposed budget.  The Board of Airport Commissioners is expected to consider a final draft the LAWA’s budget on June 7, said Gina Marie Lindsey, executive director of the airport agency.  Art Marroquin/Torrance Daily Breeze
