Frequently asked questions
What is the longest runway at KGYY?
Gary / Chicago International's primary runway, 12/30, is a 8,859-foot concrete surface with a width of 150 feet. This length supports business jet operations at all weights typically seen at this facility. A secondary asphalt runway, 02/20, measures 3,604 feet by 100 feet and serves lighter traffic. Runway 02/20 carries a use restriction for larger scheduled and non-scheduled passenger operations, so dispatchers planning larger aircraft should default to 12/30. KGYY is a towered airport, and runway assignment follows ATC coordination during operating hours.
Can Part 121 or Part 380 flights use runway 02/20 at Gary / Chicago International?
Runway 02/20 at Gary / Chicago International is restricted for certain commercial passenger operations. It is not available to Part 121 or Part 380 scheduled passenger-carrying flights with more than nine passenger seats, nor to non-scheduled passenger operations exceeding thirty passenger seats. Operators falling into those categories must plan on runway 12/30 instead, which carries no such restriction. This distinction matters for dispatchers scheduling regional or charter passenger flights into KGYY. The restriction applies specifically to the shorter 3,604-foot asphalt runway, not the primary paved surface.
Is customs available at KGYY for international arrivals?
Gary / Chicago International has CBP inspection services available onsite, along with a USDA compliance agreement. This allows international arrivals to clear customs directly at the airport rather than diverting to a nearby port of entry. The airport also operates as a towered field with air traffic control coverage. Dispatchers handling international business aviation traffic into KGYY should confirm current CBP hours and any advance notice requirements directly with the inspection office, since the compliance agreement structure can affect scheduling. No nearest alternate customs airport is listed, reflecting the onsite service.
What taxiways at KGYY are restricted to military use?
At Gary / Chicago International, taxiway F is designated for military use only, per airport remarks. Separately, an arranged ramp area supports military fixed-wing or rotary-wing parking and servicing, available on a prior permission required basis, with operations noted between 1230Z and 2330Z or later Tuesday through Friday. Dispatchers supporting military traffic into KGYY should coordinate ramp access in advance given the PPR requirement. Civilian and business aviation traffic should plan to use the general taxiway system, excluding taxiway F, for movement around the airfield.
When does KGYY see its highest volume of business aviation traffic?
Business aviation traffic at Gary / Chicago International concentrates in the fall months, with September recording the highest monthly total among the 2025 FAA TFMSC figures. Traffic builds through the spring and summer, peaking between September and October before tapering into winter. January and February show the lowest monthly volumes of the year. This seasonal pattern is worth noting for dispatchers planning ramp space or fuel logistics at KGYY during peak months. The airport's annual business aviation total for 2025 stood at 9,502 operations out of 11,888 total operations.
