Ontario International Airport Sees Remarkable Growth in March

Ontario International Airport (ONT), a key transportation hub in Southern California, has once again demonstrated its growing significance, with a notable rise in passenger traffic and freight shipments in March 2026. The airport reported an impressive increase in passenger volumes for the fourth straight month, with overall traffic reaching 574,819 travelers. This marks a 2.7% increase compared to the same month last year. The rising numbers reflect both domestic and international travel trends that have positively impacted ONT's operational landscape.

Passenger Volumes and International Travel Surge

Breaking down the passenger statistics, domestic travelers accounted for 514,777 while international travelers made up 60,042. The latter segment experienced a staggering growth of 55.2% year-over-year, underscoring a substantial recovery in international travel. Throughout the first quarter of 2026, Ontario International Airport catered to over 1.5 million passengers, which translates to a 4.1% increase from the same period in 2025.

Domestic vs. International

Interestingly, domestic passenger volume remained relatively stable, with only a slight decline of 1.2% compared to March 2025, totaling 1.3 million domestic passengers. In contrast, the international travelers nearly doubled, increasing by 58.4% compared to the previous year.

Atif Elkadi, the Chief Executive Officer of the Ontario International Airport Authority (OIAA), attributed this growth to the trust of airline partners and passengers in the airport's commitment to delivering an exceptional travel experience. Elkadi emphasized the collaborative efforts with airline partners to ensure reliable schedules and high service levels even amidst challenges, particularly concerning rising fuel costs.

Freight Shipments Experience Significant Growth

In addition to passenger growth, ONT also experienced a significant uptick in freight shipments. Overall cargo tonnage rose by 9.2%, highlighting the airport's role as a vital hub for freight services. Specifically, freight shipments surged by an impressive 15.3% in March, a trend that aligns with the airport's strategic emphasis on enhancing its cargo operations. Notably, the postal mail segment saw a decrease of 8.6%, revealing shifts in the parcel delivery landscape.

Year-to-Date Statistics

For the year thus far, ONT has handled over 208,000 tons of cargo, with commercial freight making a significant contribution to this figure. The steady growth in air freight activity is viewed favorably, and Elkadi believes it positively impacts the economic contributions of the airport to the region.

The leading air carriers at the airport for March included Southwest Airlines, American Airlines, and Alaska Airlines, reflecting diverse options for travelers and continued support from major airlines.

Conclusion

As Ontario International Airport continues to strengthen its position within the aviation landscape of Southern California, the upward trends in both passenger and air freight numbers are promising indicators of its resilience. The airport's strategic focus on improving service quality and expanding international routes plays a critical role in fostering this growth. The journey ahead may present challenges, but the commitment from all stakeholders within the ONT community will be essential for continued success. With further innovations and efforts to enhance traveler experience, ONT is well-poised to tackle the future with confidence.
