Airport Overview
Oakland County International Airport (KPTK), in Waterford just west of Pontiac, MI, is one of the busiest general-aviation airports in the United States, ranking 17th nationally with roughly 155,000 annual operations and second only to Detroit Metro within Michigan. Owned and operated by Oakland County, it serves as the principal corporate and private-aviation reliever for the Detroit metropolitan area and the surrounding automotive corridor.
Runway Capability
The field's primary instrument runway, 9R/27L, spans 6,521 feet of grooved asphalt and is supported by an ILS plus RNAV (GPS) and LOC back-course approaches. Crosswind runway 9L/27R adds 5,676 feet and a third runway, 18/36, offers 2,582 feet. This infrastructure supports the full range of light, midsize, and super-midsize jets, with larger-cabin types possible after standard performance planning for weight and temperature.
FBOs and Ground Services
KPTK is served by several business-aviation FBOs. Pentastar Aviation is the marquee operator, a multiple-award-winning, 24/7 facility with about 130,000 sq ft of heated hangars (including the only hangar on the field large enough for a Boeing 737) and in-house Fivestar Gourmet catering. Michigan Aviation, PremierFBO, Maven Aviation, and Royal Air provide additional fuel, handling, hangar, and maintenance options.
Customs and International Arrivals
Unlike many relievers, KPTK offers on-field user-fee U.S. Customs and Border Protection service, available 0700-2200 Monday through Friday and on-call at other times with advance notice. Customs user fees apply to aircraft over 10,000 lbs. This makes Oakland County a practical port of entry for international business-jet arrivals without diverting to Detroit Metro (DTW).
Safety and Planning
KPTK is a towered field (120.5/123.7) operating around the clock, with a precision ILS to 9R that allows low instrument minimums. Field elevation is 980 feet MSL, keeping density-altitude effects modest even on warm summer days. Crews should account for Michigan's Great Lakes weather and confirm approach minimums and runway conditions during winter operations.
Seasonal and Operational Factors
Southeast Michigan experiences cold, snowy winters with periodic lake-effect snow and fog, plus summer convective activity that peaks in the late afternoon. Morning departures generally encounter smoother, clearer conditions. The airport's three-runway layout provides crosswind flexibility, and its 24/7 tower and de-icing-capable FBOs support reliable year-round operations.
Regional Context
Oakland County sits in the heart of Detroit's affluent northern suburbs, roughly 8 miles from Bloomfield Hills, 10 miles from the Auburn Hills/Chrysler corporate corridor, and about 30 miles from downtown Detroit. For business travelers heading to Oakland County's corporate centers, KPTK is materially closer and faster than Detroit Metro (DTW), making it the default choice for private aviation in the region.
