We fly both a CJ1 and CJ2 in our 135 dept.
We also have a King Air 90, King Air 200, Hawker, and both CJ's. Out of all of them, the CJ's seem to get chartered the most. Mostly business men going out and back for a meeting, or a couple days stay somewhere. The low hourly-cost for being able to charter a jet seems to be very appealing to most people that fly in the CJ's. Seating is comfortable with 6 seats, and decent legroom for a jet its size.
The baggage space area leaves a lot to be desired. By the time you get on three travel bags, and two sets of golf clubs, your out of space! You learn quickly how to efficiently use all available space. Minus the golf clubs, or any fairly large items like that, its not too bad. But we rarely fly anyone without them bringing along golf clubs! And if you ever need overflow, you do have minimal room in the nose compartment, and also some are configured for extra storage space in the back of the cabin.
Hope this helps you out some!
