AirShares Elite president David Lee says that he will occasionally have a prospect ask him what's stopping him from rounding up a handful of partners, buying an airplane, managing it himself and saving a lot of money in the process? The short answer is, nothing's stopping him. The longer answer, Lee says, is that people who've been involved in partnerships before know just how complicated they can be and how much work they require to keep things going smoothly. Management service is both the best thing about shared ownership and the most expensive. It's easy to fall in love with management done right. Why is that? Try this experiment: Make a list of everything that's time consuming, annoying, painful, confusing and, when there are partners, a source of rancor among friends. We're talking about things including, but not limited to, scheduling oil changes and annual inspections, ferrying the airplane to maintenance, maintaining databases, getting insurance, making sure you're current and the airplane is too, and much, much more. Then cross out every item on that list, because you don't have to do any of it. It's that sweet.
