As Chairman of the Chicago Executive Airport Board for eight years, D. Court Harris played a significant role in the airport's growth and modernization. His leadership saw the update of the CEA Master Plan, focusing on sustainable development and generating self-sustaining revenue.
Under his guidance, the Sky Harbour development was initiated, marking the largest project in the airport's history. The airport also constructed a $3 million U.S. Customs facility to enhance its appeal to international travelers.
Harris emphasized community partnership as one of his top achievements. He expanded "Run the Runway," an annual 5K event, and extended partnerships with local business chambers.
