Although CLE is not the nicest airport in the world it has improved in the last couple years. The addtion of Concourse D, The new and longer runways, new signage throughout the entire airport, lower landing fees, new restaurants Max & Ermas, Cleveland Brews etc, addtional baggage claims, The new front area of the airport. More improvements to come are new carpet throughout the entire airport, more restaurants in the rotunda area of Concourse C, the entire ramp is going to get new concrete, Customs to be re-done, a new ATC tower...So I think the new airport director Jon Mok has done alot since he has come to CLE..
