Originally constructed as an auxiliary flight training facility for the U.S. Navy, the airport was converted to a municipal facility after World War II. It is jointly owned by the City of Newton and Harvey County, and a seven-member Aviation Commission acts as an advisory group to the City and Harvey County Commissioners. Today, EWK primarily serves Harvey County as a transport facility, but has been designated by the FAA as a general aviation reliever airport for Wichita’s Mid-Continent Airport. Open 7 a.m. to 10 p.m. daily. After-hours service available at no charge with quantity fuel purchase.
