Portland Hillsboro Airport (KHIO) is a medium airport in Portland, OR. Pilots and dispatchers reference it by ICAO code KHIO or IATA code HIO. It sits in North America.
Portland Hillsboro Airport is a regional airport primarily serving general aviation, charter, and corporate flight departments. The 6,600-foot runway means it is well-suited as a dedicated bizjet field, free from airline scheduling pressure.
The longest runway measures 6,600 ft (2,012 m), a midsize and super-midsize-class field. Representative aircraft that operate comfortably here include the Citation Longitude, Challenger 350, and Gulfstream G280. In practice this comfortable for most midsize and super-mid charter equipment.
Portland Hillsboro Airport sits near sea level at 208 ft.
Local operations run on America/Los_Angeles. 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 currently tracks 173 departing and 15 arriving private-jet legs at KHIO across the next six months of operator inventory. 2 aircraft from 7 operators are based here or fly through regularly, so most empty-leg supply originates from a local fleet rather than out-of-town repositioning.
Regional fields like KHIO 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.
