United Airlines is set to enhance connectivity from Chicago O’Hare International Airport (ORD) with new domestic and international routes launching in May 2025. The additions reflect a commitment to expanding travel options for both business and leisure passengers.

New Domestic and International Routes from Chicago

Starting May 22, United will introduce daily flights to Ontario, California (ONT) and Billings, Montana (BIL), strengthening its domestic network. The Ontario service will be operated using a Boeing 737-800, while the Billings route will utilize an Embraer E175 regional jet.
