It isn't very convenient to end up somewhere without your car. And if you factor in the time it takes to go to the airport (even if your not going through the commercial BS) and then leaving the airport when you arrive short hops don't make much sense. I used to commute from Telluride to Phoenix for a couple of years,mostly flying in puddle jumpers until I got fed up with the hassle and just drove all the time. When I factored in driving to and from and the hassles of the airport (pre 9/11, but still sucked back then too) I only saved a couple of hours on the 9 hour drive. Also, the part about people hiring private flights to move illegal things is very real. If you start flying random unknown people around you might find yourself in a world of shit. This also reminds me of Telluride. The radio station there (KOTO) runs a ride board for people to hook up with riders to share costs, and I know of at least one case where a rider was indeed carrying drugs and got busted, getting the unknowing driver in serious deep shit. I think that was eventually resolved for the driver, but not until after getting tossed in the slam and a lengthy legal battle. I used to take riders now and then on those trips until that happened and opened my eyes up.
