Ontario Municipal Airport

Ontario Municipal Airport (KONO) is a medium airport in Oregon, OR. Pilots and dispatchers reference it by ICAO code KONO or IATA code ONO. It sits in North America.

Ontario Municipal Airport is a regional airport primarily serving general aviation, charter, and corporate flight departments. The 5,006-foot runway means it is well-suited as a dedicated bizjet field, free from airline scheduling pressure.

The longest runway measures 5,006 ft (1,526 m), a light-jet-class field. Representative aircraft that operate comfortably here include the Phenom 300, Citation CJ4, and Learjet 75. In practice this limits operations to light jets, turboprops, and short-field-capable aircraft.

Ontario Municipal Airport lies at 2,193 ft elevation.

Local operations run on America/Boise. Without scheduled airline traffic, the field tends to be quieter and more flexible for charter and corporate operations — a useful characteristic for early morning, late night, or short-notice flights that would be impractical at a hub.

SkyAccess inventory for KONO updates continuously as operators publish new empty legs and one-way repositioning trips. Pricing on each leg is available with a free account, and an inventory alert will email you the moment a leg appears on the route you care about.

Regional fields like KONO are a meaningful share of US private aviation — closer to the trip's actual origin or destination than the nearest major hub, with shorter ramp-to-cabin times that are the main reason owners and brokers prefer them.

Ontario Municipal Airport is three miles west of Ontario, in Malheur County, Oregon. The National Plan of Integrated Airport Systems for 2011–2015 categorized it as a general aviation facility.
