JSX is a small airline with smallish planes (30 seat capacity) that flies to about 10 cities in the West (unfortunately not SLC). I flew from Vegas to Oakland a couple of weeks ago for the 49ers/Vikings game and it has forever spoiled me on air travel. Hands down the best flying experience I have ever had. The price about what you'd get with many of the other standard airlines (my tickets were cheaper than they would have been on Southwest).

It flies out of a private hanger at each airport, so you don't have to actually enter the airport. It was about 10 minutes from my car to the plane.
