Air Service Enhancement Program (ASEP)

Legislative Air Service Enhancement Program


Recognizing the need for reliable and enhanced commercial air service, in 2004, the Wyoming Legislature enabled the Air Service Enhancement Program, which is funded through Senate File 120.  Since the bill’s inception, 8 Wyoming communities have participated in the Air Service Enhancement Program with over $21 million being granted towards improving or retaining air service.


Today, the ASEP program is the only one of its kind in the nation and puts Wyoming at a competitive advantage in retaining and attracting air service. However, given the current climate of the airline industry, it has become increasingly difficult to provide assistance to airports and communities given the escalating costs of providing commercial air service. Regional airlines are suffering from increasingly limited crew resources from new and regulation regulations straining airlines and the small communities they serve.

Currently, there are four airports participating in the program:

  • Cody - Yellowstone Regional Airport in support of seasonal service on United Airlines to Chicago O'Hare International Airport (ORD).
  • Gillette - Campbell County Airport - For their continued jet service to both Denver International Airport (DEN) on United Airlines and Salt Lake City International Airport (SLC) on Delta Airlines.
  • Jackson Hole Airport - For expanded winter service to New York/Newark (EWR) and Washington D.C. via Dulles (IAD) on United Airlines.
  • Rock Springs - Sweetwater County Airport in support of United Airlines jet service to Denver International Airport (DEN) on United Airlines.
