The F Gates in ORD are deplorable. I always dread when I have to make a transfer there because the whole area is a dump.
If UA spends money on any gates the IAD Lower A Gates are easily the pit of any of the hub gates, much worse than even the F ones in ORD. I put on my noise canceling headphones, a Five Brothers single bacon cheeseburger and try to avoid eye contact. It's dark, it's loud. Maybe more lights, and an RCC... one can dream.
Whatever, close IAD send everything to CLE.
