I left a regional for a start-up corporate department. Single plane (King Air 200 at the time) and single pilot. It's still single pilot, but we've grown into a CJ2. Great plane that works exceedingly well for us. I don't ever see us needing anything bigger and have no aspirations to fly anything bigger.
I'd pretty much quote RI380's post word for word for the positives. I typically know my schedule several weeks to a month in advance, sometimes further out. I fly and manage the aircraft and all aspects of the flight department and am compensated accordingly. I stay where I want, have a rental car everywhere I go, and put all my expenses on the company card. I'm family to the aircraft owners and the aircraft is a source of pride for the company.
I've never looked back and wouldn't leave if SWA called tomorrow.
