United, Southwest and Delta add new flights at nation’s fastest growing airport

(Ontario, California – June 6, 2019) – The rapid expansion of commercial air service at Ontario International Airport (ONT) continues today with the inauguration of United Airlines nonstop flights serving Houston’s George Bush Intercontinental Airport (IAH). ONT now reaches 21 domestic and international destinations with nonstop service.

United’s new flight is scheduled to arrive from IAH at 10:55 p.m. (PDT), with return service to Houston departing at 11:45p.m. United already provides daily nonstop service to San Francisco and Denver from Terminal 2 at ONT, the nation’s fastest-growing airport.

“We firmly believe that by providing the exceptional customer service that airlines and air travelers have come to expect from world-class airports, Ontario Airport will be an excellent choice for travel to or from Southern California,” said Mark Thorpe, chief executive officer of the Ontario International Airport Authority. “The additional flights by some of our longest-committed airline partners reaffirm that ONT is indeed a viable aviation gateway for the region.”

The air service development wave began at ONT in April with the start of Delta Air Lines’ daily, non-stop service to its Atlanta hub. A second roundtrip will be added later this month.

Beginning next week, Southwest Airlines will add new daily service to San Francisco with four flights a day Monday through Friday, three flights on Saturday and two on Sunday.

Southwest, which operates from Terminal 4, will also add to its current service to Denver with a mid-morning departure Monday through Friday.

Summer travel through ONT is forecast to increase by nearly 14% this summer, more than four times the expected increase nationally. More than 1.6 million air travelers are expected to arrive and depart ONT between Memorial Day weekend and Labor Day.
