Part 91 Corporate/individual owner. Small flight department (ie, one airplane, and I'm the chief pilot, chief maintenance coordinator, and chief belly scrubber). My flight schedule varies month to month, but is pretty consistently about 450 hours per year for the last 4 years. No hard days off, but I have 3 weeks paid vacation per year. Typical month has me flying 10 days, averaging maybe 1 or 2 overnights per month. I probably work another 5 to 7 days a month with non-flying duties (flight planning, trip coordination, maintenance tracking, etc), but I do those duties from the comfort of my home office. Paid on salary plus annual performance bonus.
Most flights are scheduled at least a week in advance. There are usually one or two pop up trips a month, meaning that I'm asked to fly with only a day or two notice. Only once in the last 4 years I was asked "what are you doing in 2 hours?" And they are genuinely asking when it comes to pop ups; I am within my rights to decline any trip with less than 2 days notice, although I never have. Most flying is during the week, although we might occasionally leave on a Sunday night if a meeting is early Monday at a distant location. Also, some occasional personal trips on weekends - total weekend flying averages maybe 10 weekends a year, centered mostly in the summer months.
I should probably mention that I'm a career changer - I spent about 10 years as an engineer after college. By way of comparison, as a field and project engineer, I worked a five day work week (usually 20-22 days a month), 10-14 hours per day, not including my 45 minute commute home each day. I slept in my own bed pretty much every night, but honestly, I felt like that was all I was doing...going home to go to sleep. QOL was dismal, and i made less than i make now. Just a little perspective.
