For the mini-project we use a public data set, the Airline On-Time Statistics and Delay Causes
data set, published by the United States Department of Transportation at
http://www.transtats.bts.gov/. The On-Time Performance dataset records flights by date, airline,
originating airport, destination airport, and many other flight details. Data is available for flights
since 1987. The FAA uses the data to calculate statistics such as the percent of flights that depart
or arrive on time by origin, destination, and airline.
