August was another high-flying month for Ontario International Airport (ONT) where passenger volume increased by 13.4%, fueled by strong demand for summer travel in Southern California.

According to airport officials, 643,472 travelers chose the Inland Empire airport last month, including 608,360 domestic passengers and 35,112 international customers. The number of domestic travelers was 15.4% higher than August last year while the international count was 12.6% lower.

Over the first eight months of the year, ONT welcomed 4.6 million passengers, 11.9% more than in the same period in 2023.

The January through August total included 4.3 million domestic fliers and 305,267 international travelers, increases of 11.5% and 17.5%, respectively.

“Demand for travel through Ontario International Airport remained strong in August, particularly among domestic passengers,” said Atif Elkadi, chief executive officer of the Ontario International Airport Authority (OIAA). “The population and economy of the Inland Empire continue to flourish as many Southern Californians along the coast move inland seeking lower cost of living and enhanced quality of life. Airlines are responding to this favorable trend by adding more flights and destinations from our airport.”

The air carriers with the greatest passenger shares in August were:

  1. Southwest Airlines (33.9%)
  2. Frontier Airlines (16.6%)
  3. American Airlines (15.2%)
