Frequently asked questions
What runways are available at KONT?
Ontario International operates two parallel concrete runways. Runway 08L/26R measures 12,197 feet long and 150 feet wide, making it the longest surface on the field. Runway 08R/26L measures 10,200 feet long and 150 feet wide. Both runways are paved and support the large-cabin and heavy jet traffic that uses KONT. The airport is towered, and air traffic control manages sequencing across both parallel runways.
Is fuel available at KONT?
Ontario International carries both 100LL and Jet A fuel. The airport operates on an ALL / ALL / ALL attendance schedule, meaning services are available year-round. KONT is a towered, public-use airport with substantial business aviation traffic, which supports consistent fuel availability. Crews should still coordinate ground handling in advance given noted parking and ground service limits for unscheduled operations. Confirm specific fuel arrangements with airfield operations ahead of arrival.
Are there noise abatement procedures at Ontario International?
Yes, KONT has active noise abatement procedures. Full-length turbojet departures are encouraged, and a nightly preferential runway usage program applies between 2200 and 0700 local time. Operators should plan departure routing and runway selection with these hours in mind. The airport also maintains a wildlife hazard management plan, noting potential bird activity including large flocks of starlings and crows on approach to Runway 26L and 26R, along with occasional raptors. Both programs affect how flight planning should account for arrival and departure timing at Ontario International.
What are the taxiway restrictions at KONT?
Ontario International restricts several taxiway segments by aircraft size and access. Taxiway F south of Taxiway S is restricted to aircraft with a wingspan of 117 feet or smaller, and the section south of Runway 26L is restricted to aircraft with 180 feet of wingspan. Aircraft access to Taxiway R from Runway 26R is prohibited. Taxiway Y east of Taxiway W is a non-movement area, requiring all aircraft to contact ramp control for access. Portions of Taxiway S near Taxiway F are not visible from the tower, so pilots are advised to use caution in that area.
Does KONT have customs processing for international arrivals?
Ontario International has onsite customs. CBP inspection services are available according to the FAA registry, supporting international arrivals directly at the airport. This is relevant for business aviation operators planning trips that require a federal inspection stop in Southern California. KONT also handled 9,165 business aviation operations in 2025 per FAA TFMSC data, reflecting a facility built to support consistent turbine traffic. Coordination with ground handling is still advised given noted parking limitations for unscheduled operations.
