The number of travelers using Ontario International Airport has taken of tumble.
In April, numbers dropped 4.6 percent compared with a year ago. For months, traffic at Ontario International has suffered minor losses while LAX has had more passengers than previous years.
Airport officials point to fuel prices, weather and overall economic conditions as reasons for the drop in passengers.
Several flights at the airport were canceled in the first few days of April after the roof of a Southwest Airlines aircraft ripped open on a flight en route to Sacramento from Tucson. Southwest though still accounted for the majority of all passengers, about 54 percent traveling through Ontario between January and April.
