I'll add my corporate schedule for the last couple of months to the mix for comparison's sake. Like JetPilot500, I alternate legs and seats on all trips ... when I fly, it is from the left seat. I fly a King Air 200 for a small department with a fairly seasonal schedule.
I am based in North Carolina ... here's our last couple of months.
8/3: Day trip (IAD, pax drop)
8/4: Day trip (PDK, pax drop)
8/7-12: Vacation (the airplane did a two-day to IAG and a PDK turn while I was out)
8/17: Day trip (IAD, pax drop)
8/20-22: Three-day to DAL (18 hour l/o) and HOU (20 hour l/o)
8/30: Day trip to FFT (Frankfort, KY)
9/10: Day trip to INT (Winston-Salem, NC)
9/16: Day trip to GYH (Greenville, SC) for MX
August was a fairly typical month for us (10 flying days) but a little slower than usual, and September (2 flying days) was much slower than usual. Our department usually stays busiest November/December and July/August ... like I said, our company's travel tends to be somewhat seasonal.
In between trips, I had maybe a half-dozen "hangar days" ... cleaning and stocking the airplane, keeping Jepps updated, trip planning, and one day where we were at the airport ready to go when a trip canceled at the last moment due to some change in the company's plans. When I'm at the hangar on a non-flying day for these responsibilities, it is usually for no more than two hours or so.
In smaller corporate departments such as mine, the variation can be much greater than in larger, multiple-aircraft departments.
