Casper-Natrona County International Airport (CPR/KCPR) is the largest commercial airport in Wyoming by passenger volume, serving the city of Casper and the surrounding region. Situated at an elevation of approximately 5,350 feet above sea level on the high plains, the airport handles both commercial and general aviation traffic. The airport is owned and operated by Natrona County and serves as an important access point for Wyoming's energy industry, tourism, and government travelers. Despite its 'international' designation, scheduled international service is not regularly offered, and the name reflects its infrastructure capability rather than routine international operations.
