Airports in Malheur County, Oregon: Private, Municipal, Regional(All)

Airports in Malheur County, Oregon

Malheur County, Oregon, covers 9,888 square miles of high desert rangeland in the southeastern corner of the state, making aviation infrastructure critically important for its 31,700 residents. Spanning one of the largest counties by area in the continental United States, Malheur County relies on a network of public-use airports anchored by Ontario Municipal Airport and supported by Miller Memorial Airpark in Vale to connect its rural communities, serve its agricultural economy, and provide access to regional air services.

Ontario Municipal Airport (KONO)

Ontario Municipal Airport, identified by FAA code KONO and IATA designator ONO, is the primary aviation gateway for Malheur County. Located approximately three miles west of Ontario — the county's largest city — the airport sits at an elevation of 2,193 feet above mean sea level and occupies 480 acres of land just north of the Snake River plain. Its primary runway, designated 15/33, stretches 5,006 feet in length at 100 feet wide on an asphalt surface, accommodating a broad range of general aviation aircraft including light twins, turboprops, and corporate jets.

Classified as a Core, Category 3 Regional General Aviation Airport by the Federal Aviation Administration, Ontario Municipal Airport records approximately 12,930 general aviation operations per year — averaging roughly 35 aircraft movements per day. As of the most recent survey, 61 aircraft are based on the field, comprising 55 single-engine piston aircraft, 2 jets, 1 helicopter, and 3 gliders. The airport serves a vital role in the Treasure Valley agricultural corridor, supporting crop dusters, aerial survey operators, charter flights, and business aviation connecting the region to Boise, Portland, and markets across the Pacific Northwest.

Ontario's proximity to Boise, Idaho — just 55 miles and approximately 55 minutes by road — makes KONO a practical general aviation alternative for pilots operating in the Boise Terminal Control Area. Many Malheur County businesses and ranchers prefer the uncongested ramp space, straightforward pattern work, and agricultural support services available at Ontario Municipal over the busier Boise Airport (BOI), which handles commercial airline traffic. The airport's fuel services, tie-down facilities, and agricultural aviation support infrastructure make it the operational hub of Malheur County aviation.

Miller Memorial Airpark — Vale (S49)

Miller Memorial Airpark, designated S49 in FAA records, provides secondary public-use aviation access to Malheur County from its location approximately one mile southwest of Vale, the county seat. Positioned at 2,249 feet elevation, the airpark features two usable runways: the primary Runway 18/36, measuring 3,872 feet by 65 feet on a rock-asphalt surface, and a crosswind strip, Runway 10/28, at 2,100 feet by 40 feet. Miller Memorial Airpark serves Vale's 1,814 residents and surrounding Bureau of Land Management territory, supporting ranching operations, emergency medical transport, and light aircraft touring across Oregon's high desert interior.

Vale, located approximately 28 miles west of Ontario along the Malheur River corridor, experiences seasonal aviation activity related to wildfire monitoring, livestock management, and BLM land access. The airpark's two-runway configuration allows pilots to adapt to the variable desert wind conditions common across the Snake River Plain and Owyhee Plateau. For pilots flying cross-country routes through southeastern Oregon, S49 serves as a useful fuel stop and waypoint on routes connecting Boise, Burns, and Lakeview.

Burns Junction Airstrip

Deep within Malheur County's remote interior, the historic Burns Junction Airstrip sits near the junction of Oregon Route 78 and US Highway 95, at coordinates approximately 42.77°N, 117.85°W. This historic airstrip served as an essential transportation link for the county's most isolated ranching and mining communities during earlier eras of aviation. While commercial operations have long ceased, the airstrip represents an important part of Malheur County's aviation heritage and continues to be referenced in backcountry flying guides for pilots exploring Oregon's vast southeastern quadrant.

Geographic and Agricultural Context

Understanding aviation in Malheur County requires appreciating the county's extraordinary scale and economic character. With a population density of just 3.2 people per square mile across nearly 10,000 square miles, ground transportation alone cannot adequately serve the county's ranching families, emergency responders, and agricultural operators. The Treasure Valley in the county's northeastern corner — fed by irrigation from the Owyhee and Snake Rivers — produces high-value crops including onions, sugar beets, and potatoes that drive regional agribusiness aviation demand. Ontario, Nyssa (population 3,188), and Vale collectively anchor the county's developed corridor, while vast BLM-administered rangeland to the south and west remains accessible primarily by air.
