Flew through IAD this weekend ---- BUF-IAD-PVD and then PVD-BUF-IAD. All I can say is wow...A gates for UA ( gates 1-6 to be more specific) are like a cattle call when boarding. Felt like I was in a third world country. Poor boarding practices and confusion all around. Off course flight delays on either end of my trip didn't help. But that's for another post.
