From what I’ve heard from a current employee Alpine is slowly displacing Ameriflight from Salt Lake. Billings, Denver and Salt Lake are in the process of having 4 day weeks for schedules. Their Sioux Falls hub is actually 3 weeks on 1 week off. 2 weeks on a typical UPS schedule fly out morning come back home at night, 3rd week is a reserve run so out and back by 11 am if you fly at all. 4th week is a fulll paid week off. Must be dual qualified to fly the 1900 and 99. Finally if you don’t have thick skin and get irritated easily avoid Denver at all cost. Not because of Alpine but because of UPS. Hope that helps
