St Clair County International Airport (PHN)

St. Clair County International Airport (PHN) is a premier general aviation and international entry point located in Kimball Township, Michigan, approximately 5 miles southwest of Port Huron. The airport features a dedicated passenger terminal and Fixed-Base Operator (FBO) facility that serves as a critical hub for cross-border travel between the United States and Canada. It acts as a vital infrastructure link for the region, specifically supporting an adjacent 80-acre business air industrial park and regional logistics operations.

The terminal infrastructure provides a variety of specialized amenities for travelers and flight crews, including comfortable crew lounges, private 'snooze rooms' for rest, and on-site shower facilities. Passengers have access to functional waiting areas and free high-speed Wi-Fi throughout the building, ensuring a professional environment for both business and private aviation. As an official 'International Airport of Entry,' the facility features 24-hour on-site U.S. Customs and Border Protection (CBP) services to streamline the processing of international arrivals.

Technical services at the field are comprehensive, managed by the on-site FBO which provides both full-service and self-service fueling for 100LL Avgas and Jet A fuel. The airport features two substantial asphalt runways, including a 5,103-foot precision instrument runway (04/22) capable of handling a wide variety of corporate jet aircraft. Ground transportation is well-supported by pre-arranged rental car services and local taxi ranks, providing a quick 10-minute link to the Blue Water Bridge and the diverse business districts of Port Huron.
