China Airlines will fully restore daily round-trip service between Southern California's Ontario International Airport (ONT) and Taipei beginning March 26, 2023, ONT officials announced.

The return of daily service connecting ONT and Taoyuan International Airport (TPE) marks a major milestone in Ontario's recovery of international air service, all of which was suspended at the onset of the COVID-19 pandemic nearly three years ago.

After suspending service in March 2020, China Airlines resumed ONT-TPE flights in June 2021, gradually increasing service levels as demand returned. The resumption of daily service occurs at the same time that China Airlines marks its five-year anniversary at ONT.

The first carrier to offer nonstop, transoceanic passenger service to ONT after its transition to local ownership, China Airlines will upgrade the aircraft operating the route from an Airbus A350-900 to a larger Boeing 777-300ER, increasing seat capacity from 306 to 358 across premium business, premium economy and economy classes. The service is also scheduled to provide customers with seamless one-stop connections to additional destinations throughout Asia.

TPE is the primary international gateway to northern Taiwan's more than 9 million residents, while ONT is the closest and most convenient international gateway airport for more than 10 million Southern California residents in San Bernardino, Riverside, northern Orange and eastern Los Angeles counties.

Domestic air travel through ONT surpassed pre-pandemic levels in 2022, a milestone achieved by few other airports in California.
