Airport Overview & History
Chicago O'Hare International Airport (KORD) opened to commercial traffic in 1955 on the site of the former Orchard Field — the origin of the 'ORD' code — and grew into one of the planet's busiest airports. It is a primary hub for United Airlines and American Airlines, with eight runways and four passenger terminals owned and operated by the City of Chicago. For private aviation it remains a fully capable but congestion-heavy option in a metro area rich with dedicated business-jet alternatives.
Runway Capability
KORD's eight runways are anchored by 10L/28R at 13,000 ft, with three additional runways over 10,000 ft (10C/28C, 10R/28L, 14R/32L). This easily accommodates the entire business-aviation fleet — light jets through ultra-long-range types like the Gulfstream G650/G700, Global 7500, and Boeing BBJ — at full payload and fuel. Field elevation is a modest 672 ft MSL, so density-altitude penalties are minimal year-round.
Charter & FBO Considerations
Private flights at O'Hare are handled exclusively by Signature Aviation, the field's only FBO, which sits apart from the airline terminals — passengers never touch the main concourses. Although ORD is not an FAA slot-controlled airport like JFK, LaGuardia, or Reagan National, it is intensely busy, and prior permission (PPR) plus advance handling arrangements through Signature are strongly recommended. Expect to be sequenced into heavy commercial traffic, with the associated landing fees and potential ground delays.
Safety & Planning
All primary runways are ILS-equipped with CAT II/III capability and backed by RNAV (GPS) approaches, keeping KORD usable in Chicago's frequent winter fog and low ceilings. Operators should file IFR, plan for airline-flow sequencing, and build schedule buffers around peak arrival and departure banks. Coordinate ground handling, fuel, and any customs needs with Signature well in advance.
Seasonal & Operational Factors
Chicago winters bring snow, freezing precipitation, and extended IFR conditions; de-icing at O'Hare is routine and can add 15-45 minutes to a departure during storms. Summer afternoons see convective activity that triggers ground stops and arrival delays across the airline flow. Morning departures generally offer the smoothest, most predictable operations.
Regional Context & GA Alternatives
Because O'Hare is congested and carries airline-grade fees, most Chicago-bound private travelers prefer a dedicated reliever. Chicago Executive (KPWK) in Wheeling is the regional favorite for business jets, roughly 18 miles northwest of downtown with multiple FBOs and lower fees. Chicago Midway (KMDW) on the South Side offers strong FBO options and fast downtown access, and DuPage (KDPA) in the western suburbs is an executive favorite. The Jet Finder can compare KORD against PWK, MDW, and DPA on fees, runway needs, and drive time to your destination.
