What's Happening?
Ontario International Airport (ONT) is leveraging record traffic growth and new services to enhance its role as Southern California's second international gateway. Recent developments include United Airlines' daily nonstop service to Chicago O'Hare and Southwest Airlines' service to Baltimore-Washington, marking ONT's first connection to the U.S. capital region. Starlux Airlines has initiated flights from Taipei, complementing existing services from China Airlines. Volaris has expanded its presence with new routes to Los Cabos, Morelia, and Leon/Bajio. These additions have contributed to ONT recording its second-highest passenger total in July 2025 and its busiest month for international traffic. The airport aims to further grow its international footprint, particularly in Latin America and the Asia-Pacific region, supported by its facilities and space for long-haul services.
Why It's Important?
The expansion of Ontario International Airport's network is significant for Southern California's air travel market, which is the second-largest in the U.S. The airport's growth strategy aims to accommodate the region's nearly 20 million residents, providing an alternative to Los Angeles International Airport. This expansion could enhance economic opportunities in the Inland Empire region, which has experienced job and income growth. Despite macroeconomic concerns and tariff announcements affecting travel demand, ONT has maintained consistent passenger growth, outperforming peer airports across California and the U.S. The airport's development could attract more international carriers, boosting local tourism and business travel.
What's Next?
ONT plans to continue expanding its international services, focusing on Latin America and the Asia-Pacific region. The airport's facilities are prepared to handle additional growth from international carriers. However, recent macroeconomic concerns and tariff announcements may pose challenges to travel demand. ONT's ability to maintain its growth trajectory will depend on its capacity to attract new carriers and manage economic headwinds. The airport's strategic position and infrastructure readiness will be crucial in achieving its long-term expansion goals.
