Vinton County Airport (ICAO: K22I) is a small general aviation facility located near McArthur, Ohio, the county seat of Vinton County. It serves private pilots, recreational flyers, and light aircraft operations in one of Ohio's most rural and sparsely populated counties. The airport operates without scheduled commercial airline service and functions primarily as a public-use general aviation field. It provides basic infrastructure for small aircraft, including a single runway and limited on-site amenities typical of rural county airports. Vinton County itself is known for its forested terrain and low population density, making the airport an important resource for air access to a region with limited transportation infrastructure.
