More bad news for the Inland Empire’s favorite airport: Passenger traffic at Ontario International Airport continues to nosedive, according to figures released by its owner, Los Angeles World Airports. In June, ONT saw 8.5 percent fewer travelers than in June 2012. At the same time, Los Angeles International enjoyed a healthy increase in passenger traffic. In June, LAX hosted 6.5 percent more passengers than in June 2012. Want the hard numbers? ONT flew 341,967 passengers in June, 31,685 fewer than last June. LAX flew 6,114,514 passengers in June, 374,610 more than last June. Thanks, LAWA.
