They're interesting, but due to limited numbers of seats might have more appeal to businessmen who are also pilots. One huge advangtage of them is being able to fly directly to smaller airports with limited commercial service nearer the destination.
I had a friend who flew a Mooney prop plane with a maximum speed of about 200 knots, and he bragged that it was faster to fly the plane than to sit and wait for the big jets at the airport.
That was before 9/11, so it’s probably doubly true today that a prop plane can actually beat a big commercial jet for convenience.
It sure was nice to determine our flight time by when we wanted to leave, and he could load an amazing amount of stuff on the plane for trade shows and the like.
I always looked wistfully at the private jets, though - there’s something very glamorous about them that his Mooney seemed to lack.
I’m afraid I was better at using the navigation gadgets and flipping the frequency on the radios than I was at flying the plane, though!
