Slightly OT - Talked to ORD gate agent a couple days ago, she said there is a small 7am bank, a big 9am bank, a big 2pm bank, a big 6-ishpm bank, and a small 8pm bank of flights. Guessing you're there during the slow time. She also added, UA had originally hoped to add more flights for August, but with demand going back down again doubts they will.
