Ontario International Airport (ONT) anticipates a record-setting summer with 2.22 million passengers expected between May 23 and September 1—up 1.7% from last year—as airlines expand flights to 12 popular destinations in the U.S. and abroad.
The airport projects nearly 664,000 passengers in June, followed by over 672,000 in July and 671,000 in August. More than 2.85 million seats will be offered, a 3.4% increase year-over-year, with nearly 78% occupancy expected.
New and expanded domestic routes include daily service to Baltimore and Chicago O’Hare, additional flights to Dallas, Sacramento, Salt Lake City, and Seattle, and resumed daily service to New York JFK. Internationally, Volaris is adding or increasing service to Guadalajara, León, Los Cabos, and Morelia, while STARLUX Airlines will begin four-times-weekly service to Taipei on June 2.
CEO Atif Elkadi said ONT continues to build trust through a “world-class, stress-free experience,” supported by amenities such as premium lounges, duty-free shopping, convenient parking, and ride-share access. He also reminded travelers of the May 7, 2025 deadline for Real ID compliance.
Ranked California’s top mid-sized airport by J.D. Power, ONT serves more than two dozen major destinations and is reinforcing its role as a key Southern California travel hub.
