Passenger volume at Ontario International Airport (ONT) grew by more than 18 percent in August, with arriving and departing passengers totaling 458,029 travelers, compared with 387,351 for the same month in 2017.

The August figure included 435,690 domestic passengers, up 16.2 percent from 375,109 a year ago, and 22,339 international travelers, 82.5 percent more than the 12,242 in August 2017.

“The consistent increases in passenger volume affirm what we are doing to develop Ontario into a world-class gateway and create a firstrate airport experience,” said Alan D. Wapner, president of the Ontario International Airport Authority (OIAA).

In the first eight months of 2018, more than 3.3 million travelers moved through ONT, an increase of 13.2 percent over the same period a year ago.

August saw the start of Frontier Airlines’ daily, non-stop service to Orlando. Earlier this month, JetBlue launched nonstop service to New York’s JFK Airport.

ONT also recently completed multi-million upgrades of the airport’s dining and retail concessions.
