US airline delays

For my visualization project at Udacity’s dataanalyst nanodegree I have chosen to use airline traffic data.  I have a particular interest in flying (did my minor in aerospace) so I was curious about what data I could use regarding flying. The Bureau of Transportation Statistics provides all kind of data regarding US airlines including delays. Because a common source of frustration for travellers is delay, I decided to analyze airline delays.

In my visualization, I have aggregated the delays per year for the largest US carriers for which data was available for the years 2007-2015.
