The Ontario International Airport Authority (OIAA) welcomed news that Delta Air Lines will launch daily, roundtrip service between the Inland Empire and Atlanta in 2019. Delta is the third carrier to announce new transcontinental flights from Ontario International Airport (ONT) in recent months.

"We are thrilled to add Delta’s nonstop service to its Atlanta hub, a key development in Ontario’s evolution as a gateway airport," said Alan D. Wapner, president of the OIAA. "The world’s busiest airport, Atlanta offers Southern Californians a world of opportunities for air travel through Delta's extensive global network."
"In just two years since the airport’s transition to local control, we've made tremendous strides in improving our facilities, services and amenities and, as a result, airlines and air travelers are bullish on Ontario,” Wapner added.
According to Delta, ticket sales for flights between Ontario and Hartsfield-Jackson Atlanta International Airport will begin Saturday, Oct. 20, 2018, with flights starting April 22, 2019, using Boeing 737-900 aircraft.
Delta, which currently flies to Salt Lake City from Ontario three times a day, is the third carrier to announce plans for nonstop flights to the East Coast this year. Frontier Airlines began service to Orlando in August while JetBlue Airways launched daily flights to New York's John F. Kennedy International Airport last month.
“The new Delta service is truly a feather in our cap,” said OIAA Commissioner Jim W. Bowman. “We are going to great lengths to show Ontario is a first-rate airport with the infrastructure and know-how to deliver a world-class customer experience, not to mention ample capacity for future growth.”
Ontario is on pace to handle five million passengers this year, its highest total since 2008. The airport’s capacity is estimated to be 30 million total annual passengers.
Ontario recently completed a multi-million dollar upgrade of its dining and retail concessions featuring popular national brands and Southern California-based enterprises which cater to local tastes. In addition, app-based ride hailing services including Uber and Lyft were added to ONT's ground transportation program last year.
