I pulled historical flight schedule data from the USDOT to produce this basic chart of United DEN operations by time of day during peak summer 2022.
The primary hub bank times are easy to see.
8 AM is small but omnidirectional, mostly fed by close in regional destinations in the Mountain West
10 AM is larger and mostly eastbound.
11:30 AM ~ is mostly westbound
1:30 PM is mostly eastbound (and growing in Summer 2023)
3:45 PM is smaller and more westbound and regional.
5:30 PM is large and mostly eastbound.
7:00 PM is mostly westbound.
8:40 PM is small, more regional, and more omnidirectional. (This one is growing a bit in 2023)
