I have been taking Salt Lake Express since the began service to Pocatello many years ago. They have continually increased their geographic coverage and scheduling offerings since then. I feel that they have made air travel affordable for those of us who do not live in major air transportation hubs who have experienced decreasing air service to smaller communities over the decades since deregulation of air travel in the US. I can book flights and be sure that I can get to the airport without the hassle of driving my own car. They also are very accommodating when flights are delayed and the dispatcher will call your cell phone and will wait for you if you are running through the airport!
