Does anyone have any statistics showing the overall load factors for an airline for each day of the week? I have always had a feel for which days are busiest with some vague reasons. Mondays and Fridays should be busy since the business travelers are returning and leaving home, right? Saturdays and Sundays should be light since business travelers don't travel, right? But then at the same time, the airline usually cuts frequencies on Saturdays to make up for this.
Let's assume no holidays and travel only within the 48 contiguous U.S.
