“As we head into another record-setting summer travel season, ONT is proud to serve as Southern California’s fastest-growing and most convenient airport. We’re not just connecting travelers to more flights and more destinations than ever before, we’re connecting our community to the world. ONT continues to grow as a vital gateway for Southern California,” said Atif Elkadi, chief executive officer of the Ontario International Airport Authority.
Airlines are introducing new flights or expanding existing service to a dozen destinations from ONT this summer, including Baltimore/Washington, Chicago O’Hare, Dallas-Fort Worth, New York JFK, Salt Lake City and Seattle, as well as Taipei and four destinations in Mexico.
Ontario International expects 2.2 million air travelers over the summer, an increase of 1.7% compared with last summer.
The growth in 2025 comes on the heels of a banner year in 2024, when Ontario reported more than 7 million passengers, an increase of 10.2% over 2023 and 27% higher than pre-pandemic 2019. These achievements have made ONT the fastest-growing among medium- and large-size airports in California, and the 2024 count represented a 67% increase since 2016, when the airport was transferred to local control from the City of Los Angeles.
