When I started flying more than a dozen years ago and started to talk about buying an airplane someday, my father-in-law asked me to name some of the economic advantages of traveling via general aviation instead of driving, taking a train, or using the airlines.
I had to break the news to him that, as far as I know, there are no pure monetary savings to be found in private aviation. If you consider time, convenience, and self-determination among your forms of currency, however, you can begin building a strong case for getting around in your own airplane.
