Sure you can prevent it...you can buy or lease a jet and decide exactly who gets to ride on it.

But no, if you're going use mass transit, you have to deal with...you know...other people who use mass transit. *shrug*

Frankly, I'd prefer an inflight experience that is solely me, one flight attendant ensuring that my glass of Glenfarclas is never empty, one really good sushi chef making sure I don't get hungry, and two pilots. But until someone can manage to arrange this for $99 each way to either coast (with a nice serving of bonus miles good towards future free trips), I guess I'll have to deal with other people...
