Airport Overview
DuPage Airport (KDPA), in West Chicago about 29 miles west of downtown Chicago, is among the busiest general aviation airports in Illinois and a cornerstone corporate reliever for the metro area. Owned and operated by the DuPage Airport Authority, the field combines multiple runways, a 24-hour FAA tower, ILS approaches, and on-site federal Customs, giving business operators a full-service alternative to O'Hare (ORD) and Midway (MDW) without airline congestion or commercial terminal delays.
Runway Capability
The primary 7,570 ft asphalt runway (10/28) supports light jets through large-cabin aircraft such as the Gulfstream G650 and Bombardier Global 7500 under standard conditions, while secondary runways of 5,100 ft and 3,400 ft provide outstanding wind coverage. The 759 ft elevation keeps density altitude manageable, so most charter aircraft depart at or near full payload even in summer heat.
Customs & International Access
KDPA is a genuine international gateway. A dedicated U.S. Customs and Border Protection facility opened in 2022 on the first floor of the DuPage Flight Center, allowing private aircraft to clear inbound international flights on-field. Customs clearance should be coordinated at least 24 hours in advance through the FBO; this makes DuPage a convenient port of entry for transborder business travel into the western suburbs.
Charter Considerations
DuPage Flight Center is the single, airport-operated FBO, which simplifies handling and keeps fuel pricing competitive relative to downtown-adjacent fields. The terminal offers crew lounges, conference space, rental cars, and concierge ground transportation. For Chicagoland charter, KDPA is often the best balance of runway capability, customs access, and quick highway connections to the western and northwestern suburbs.
Safety & Planning
A 24-hour FAA control tower and dual ILS-capable runways make KDPA reliable in low ceilings and winter weather. Flight planning should account for seasonal frontal passages that can drop the field to IFR minimums and for summer convective activity that builds after early afternoon. Morning departures typically offer the smoothest, most schedule-reliable conditions on this corridor.
Regional Context
DuPage sits within the dense Chicago-area airport network alongside Aurora Municipal (KARR), Chicago Executive (KPWK), and the airline hubs at O'Hare and Midway. For travelers headed to the western suburbs of the DuPage and Kane County corridor, KDPA frequently offers shorter ground times and faster ramp access than the commercial airports, while still providing tower service, instrument approaches, and customs.
