Like others have said, flying for a private individual can go either way. Some of the owners are very nice, treat their crews like friends (if not family), let the crews tag along on the fancy vacations and trips. I worked at an FBO with a large charter and management department, one of the aircraft owners kept a convertible Porshce for his pilots to use when they were in town, and they (crew, owner and his family/friends) partied like rock stars together when they weren't on business trips.

There are also the high maintenance owners who think the world belongs to them and other people are only around to serve. I've seen plenty of crews bring the boss in for what was supposed to be a week long stay, only to be called the next day to go somewhere else because the boss was bored. But hey, that's why they have their own plane, to do whatever they want, whenever they want.

So it just depends on the owner. Finding those jobs is all about being in the right place at the right time, making the right friends, and networking.

Sorry for the long post, for some reason I felt like typing tonight.
