Does the time of flight affect the chances of it being delayed? Is there a preferred day or month to fly if you want to minimize the chances of your flight being delayed?
Data was gathered from the Department of Transportation's web site On-Time Performances Table, between November 2016 and October 2017 (inclusive).
The data was processed in order to create a histogram of late flights by different time periods. Delay is considered when a flight arrived more than 15 minutes after its planned time. The data includes all domestic flights and delays for all reasons (security, weather, etc.)
For any available graph (day of week, day of month, and month of year) the percentage of delayed flights is shown. The category with the most delays is marked with a red bar, while the category with the least delays is marked with a green bar.
