  "connection_tips": "St. Clair County International Airport (PHN) is a premier general aviation and corporate hub serving Port Huron, Michigan, and the Canadian border. It handles NO scheduled commercial airline flights. Ground transport is straightforward; on-site car rental agencies (Enterprise) and local taxis are readily available on call.\n\nA significant tip: the airport is a designated U.S. Customs Port of Entry with 24/7 staffing, making it a critical 'Technical Stop' for aircraft crossing between the USA and Ontario. The facility is located just 10 minutes from the Blue Water Bridge to Sarnia, Canada Customs staffing makes the airport valuable for technical stops and cross-border aircraft movements, so the ramp often feels more like a working entry point than a leisure field.\n\nMajor FBOs provide high-quality executive lounges and pilot services. If you need a commercial connection, Detroit Metropolitan (DTW) is approximately 1 hour and 15 minutes to the south via I-94 That mix of customs access and FBO service is what makes Port Huron straightforward for general aviation crews who need a clean U.S. entry point. A bridge or customs stop should already be understood, because the real use of the airport is the technical stop for Sarnia or Ontario crossings there.",
