According to the study when all annual spending related to airports, airport tenants, capital investment and air visitors is considered, the study estimates Wyoming airports support $1.4 billion in total annual economic activity or output.

The study also found that visitors who arrive in Wyoming on commercial airline flights spend $547.2 million in the state annually, and that spending supports 8,438 jobs with an annual payroll of $318 million. The airports themselves account for 283 jobs in administration, operation and maintenance, with an annual payroll of $13.7 million.

The study completed by consultants ICF-SH&E, Kramer Aerotek and Jviation estimates the airports and the activities they support also generate $55 million in state and local tax revenues each year.
