Which type of planes are most susceptible to delays?
Source of Data
Data was gathered from the Department of Transportation's web site On-Time Performances table, for all flights departing from the top 50 busiest US airports in 2017. We chose to look at trends for the 7 most common types of aircraft.
Two charts are below.
The first is a stacked bar chart which indicates percent occurrence of delay, categorized into 5 levels. For this, we filtered down just to flights that were departing Boston. This chart is interactive, so you can click on each delay category in the legend to see a subset of the data. This chart was made with Plotly.js
