United Airlines is set to introduce a new nonstop service between Chicago and Ontario, California, starting in May 2025. This marks the airline's fourth route to the southern California airport. Additionally, United will launch two more routes from Chicago to Billings and Halifax, operated by SkyWest Airlines.

The Chicago O'Hare International Airport (ORD) to Ontario International Airport (ONT) service will commence on May 22 with daily flights using the Boeing 737-800. The flight schedule includes UA1032 departing ORD at 19:55 and arriving at ONT at 22:26, while UA2144 leaves ONT at 07:00 and reaches ORD at 13:03. Alan Wapner, President of the Ontario International Airport Authority Board of Airport Commissioners, commented on the new service saying, "We are thrilled that United has chosen to add service from Ontario to its home base in Chicago."

Ontario Airport saw over seven million passengers in 2024, marking significant growth compared to previous years. Currently, United offers up to 28 weekly flights to Ontario from Denver, Houston, and San Francisco.
