What the data says
Departure time hasn't mattered much.
On-time rates stay between 91% and 92% across the day.
Sunday scaries are real for this one.
LAX–MSO flights arrived on time 100% of the time on Mondays and just 77% on Sundays. That gap is worth planning around.
It basically never cancels.
Out of 109 scheduled flights, only 0.0% were cancelled.
