Flew out of CLE two weeks ago and back into CLE last week. Very interesting airport. Forgive me if this repeats an earlier point (I haven't read all 643 comments on the thread) but apparently they're trying to hurry up construction to get the renovations complete before the Republican National Convention is held in Cleveland this July. I will say, I got to the airport earlier than usual (1 hour before a domestic F flight) for this reason, but I didn't need to. Despite the construction, I was able to get to my gate in ~15 minutes. I will give the airport HUGE props for having ample staff around directing passengers through the construction to security checkpoints, gates, etc. More than needed, probably. Made it extremely efficient and effective despite the renovations.
