Airline Delays
Every airline tries to launch it's airplanes on a predictable schedule. But delays happen. This application will examine departure delays at major Florida airports during January 2008.
Dependent Variables
- Delay time: Can remove extremely long delays as they are statistically very rare.
- Departure Airport: Only the 5 major airports in Florida are listed.
- Airline: All airlines with flights at the 5 airports are listed.
Data Preparation
Original flight data for 2008 downloaded from http://stat-computing.org/dataexpo/2009/the-data.html
Pre-Processing:
- Only January flights are considered. In general, the weather in Florida in January is mild and therefore less weather-related delays should be in the data set.
- Removed Cancelled and Diverted flights
- Filter to only the following airports: “JAX”,“MCO”,“MIA”,“FLL”,“TPA”
- Restricted to only delays of less than 120 minutes
- Airline name is shortened to only the first word for display

Additional months should be studied to determine if January is the best choice for comparisons.
