American Airlines Launches Daily Ontario-Chicago Service in December

The daily service will utilize a Boeing 737 configured with 172 seats, split across First Class, Main Cabin Extra, and standard Main Cabin cabins. Travelers can book the flights starting July 6 via the airline’s website. The schedule features a 6:00 a.m. departure from Ontario, arriving in Chicago at 12:15 p.m., with the return leg departing O’Hare at 6:15 p.m. to reach Southern California by 8:48 p.m.

Alan D. Wapner, president of the Ontario International Airport Authority, characterized the move as a reflection of growing regional demand. The new route adds competition to an existing market currently served by United Airlines and deepens the airport’s connectivity to American’s global network, which already includes hubs in Dallas-Fort Worth, Charlotte, and Phoenix. This addition coincides with the tenth anniversary of the airport’s transition to local ownership, a period during which seat capacity on American Airlines flights out of Ontario has surged by 66%.
