Long delays on Monday mornings at Heathrow: Misconception

In this post, I examine flight departure delays out of Heathrow by weekday and time. To my surprise, those long and frustrating waits on the tarmac on Monday morning could not be back up by statistics.

We have used Tableau in our analysis. To get the most of this insight click on the visualisation below to bring the data to life.

The average departure delay from Heathrow is 38.2 min and the busiest hour is Friday at 9am (55.75 min delays). Monday morning delays average around 26min well below the average.

Dhaka and Colombo have on average the highest departure delay with 137 and 123.9 minutes respectively.
