Airport Overview
Green Bay Austin Straubel International Airport (KGRB), owned by Brown County, is northeast Wisconsin's primary airport, situated in Ashwaubenon about 8 miles southwest of downtown Green Bay and roughly 4 miles from Lambeau Field. It blends scheduled airline service with a robust general and business aviation operation, handling about 47,000 aircraft movements a year, the majority general aviation and air taxi.
Runway Capability
Two grooved concrete runways, 18/36 at 8,700 feet and 6/24 at 7,700 feet, both 150 feet wide, support the entire business-aviation fleet from light jets through heavy and ultra-long-range types. The generous lengths provide comfortable margins for hot-day and high-gross-weight departures, and the intersecting layout offers crosswind options in all seasons.
Charter Considerations
KGRB is fully jet-capable with two competing full-service FBOs, Jet Air Group and Avflight Green Bay, both offering Jet-A, hangar space, and crew amenities. Demand spikes around Green Bay Packers home games and corporate travel to the region's paper, packaging, and manufacturing base. Booking ramp and hangar space well ahead is advisable on game weekends.
Customs & International Arrivals
U.S. Customs and Border Protection service is available at Green Bay, handled through the FBOs, making KGRB a viable port of entry for international business-jet arrivals. Operators should arrange CBP clearance in advance through their FBO to confirm staffing and timing for the inbound flight.
Safety & Planning
An FAA control tower operates 118.7 from 0530 to 2330 local; outside those hours the field is non-towered with CTAF procedures. Approaches include ILS/LOC to Runways 06 and 36, RNAV (GPS) to all runway ends, and a LOC back-course to Runway 24, supporting reliable IFR access in marginal weather. There are no published weight, noise, slot, or curfew restrictions.
Seasonal & Operational Factors
Lake Michigan's influence drives winter weather variability, and de-icing is available on field through Jet Air Group; crews should budget added time during frontal passages that can hold IFR ceilings for a day or more. Summer convective activity tends to peak in late afternoon, so morning departures generally see smoother, clearer conditions.
Regional Context
KGRB anchors the Fox Valley corridor and is the closest jet-capable, customs-equipped airport to Green Bay, Lambeau Field, and the surrounding manufacturing region. Appleton International (KATW) lies about 22 nautical miles south as an alternate, but Green Bay's two long runways, tower, and dual FBOs make it the preferred choice for most corporate and charter missions to the area.
