I believe he went to Island Air Express, which is why I posted my original question. After watching early adopter Caravan operators crash left and right I can't believe those things are operating in SE. I'm probably not up on anything either, so probably the answer is that a guy with a slug of Alaska time can pull that off safely if working at a careful and conscientious company.
And dust, it's funny you mention Metro because I'm currently in Oregon and those are the guys that got me thinking. They had an opening in Klamath Falls for a PC-12, so I applied but crickets so far. I have no PC-12 time, but plenty of hours and multi-turbine PIC. Maybe its the damn 121 time. I should omit that from a resume. I'd be interested in asking your friend about them.
