Once again, the numbers tell the story. Passenger numbers are up at LAX, down at Ontario International Airport. LAX enjoyed nearly a 5 percent increase in May, compared to May 2012. ONT suffered a 9.33 percent drop, the biggest month-over-month decline since 2011. Last summer, a spokeswoman said the Inland airport had reached a “stable low.” No. It has continued its downward trajectory since 2007. When you compare the first five months of this year to the same period last year, LAX is up 3.62 percent, ONT down 7.99 percent.
