History is being made at Ontario International Airport, thanks in large part to a new slate of international flights that debuted in recent weeks.

On Monday, airport officials announced that July was its second-busiest month in the airport's history, with the largest total number of international travelers ever recorded.

ONT reported 681,912 total passengers in July, surpassing the previous high mark set for that month, which was set in 2007. July 2025 was also 2.3% higher than July 2024.

Last month's passenger total includes nearly 625,000 domestic travelers, which is slightly down from the previous July. But a 53% increase in international travelers (56,954) propelled July 2025 into the airport's history books.
