Alright. If you're expecting 5 star service and a conceirge to whisk your stuff away to a waiting plane.... you really shouldn't be flying through CLE. You should be sitting comfortably on chaise lounges sipping champagne (or your drink of choice) as the private plane is dusted off, bought out to the runway (AKA your driveway) and you a chauffered golfcart arrives to take you the 20 feet from said chaise lounge to the plane stairs.
For the rest of the world, airports are a midway point between stops. A place where you should be able to get a decent bite to eat, satisfy the urge to pee at really inconvenient times, and where you should be expected to be prodded, poked, scanned etc and indeed stand in unbearably long lines to do so. And when you think about that, the Cleveland Airport is definitely A-OK!
No Long lines. Decent amenities. Great connectivity to Cleveland (Admit it... Traffic means it's going to take you 35 mins from downtown instead of 20). Ok Connections (fine... it's a bit of a stretch... but good connections to NYC, Chicago and Boston... ALL of which have great connections!)....
This place gets a 3 star as far as airports go in my book (and to be clear here... there aint no such thing as a 5 star airport, unless it's the private jet scene I described above)
