Airline service was subsidized by the Essential Air Service program until May 2004,[5][6] when subsidies ended due to federal law not allowing a subsidy over $200 per passenger for communities within 210 miles of the nearest large or medium hub airport (Eppley Airfield, a medium hub serving Omaha, Nebraska).
