Ontario International Airport

Ontario International Airport (KONT) is a large airport in Ontario, CA. Pilots and dispatchers reference it by ICAO code KONT or IATA code ONT. It sits in North America.

Ontario International Airport is a commercial-airline hub that also handles a steady stream of private and corporate traffic. Private operators share airspace and ground infrastructure with airline movements, which can mean longer taxi times during scheduled banks and the need to book FBO ramp space ahead of major events.

The longest runway measures 12,197 ft (3,718 m), a ultra-long-range-class field. Representative aircraft that operate comfortably here include the Gulfstream G650, Bombardier Global 7500, and Dassault Falcon 8X. In practice this transcontinental and transoceanic operations without performance penalties.

Ontario International Airport sits near sea level at 944 ft.

Local operations run on America/Los_Angeles. Because the field hosts scheduled airline operations, private operators should expect a defined slot environment, possible CDM coordination at peak banks, and limited ramp availability during major event weekends. Booking FBO ramp space in advance is normal practice.

SkyAccess currently tracks 520 departing and 417 arriving private-jet legs at KONT across the next six months of operator inventory. 13 charter operators have run trips through this field in our recent inventory window.

For high-volume bizjet markets like Ontario, KONT is typically the default for international arrivals and large-cabin departures, with quieter satellite fields nearby that operators use to avoid peak-weekend congestion.
