Here is the latest article from the Aspen Times By Scott Condon
When United Express switched its aircraft that serves Aspen, it essentially dumped a gas guzzler for a fuel-efficient model, according to research by an Aspen businessman.
Bill Tomcich, president of Stay Aspen Snowmass, a central bookings office, figured the shift from BAE-146 aircraft to the CRJ-700 could improve fuel efficiency by about 40 percent.
Air Wisconsin used the BAE-146 when it operated United Express flights between Aspen and Denver. Sky West took over operations in April and switched to the CRJ-700.
